Revolution in irrigation: SWEEP and nanobubble

Priya Chauhan, Bhavya Akotiya

Index Institute of Dental Sciences, Indore, Madhya Pradesh, India

There is continuous innovation in irrigation technology aiming to achieve complete disinfection of the root canal system including the minutest ramifications of the pulp canal space. A recently introduced Novel SWEEPS (shock wave enhanced emission photoacoustic streaming) technology using Er. YAG. laser has been developed to improve the cleaning and disinfecting efficacy of laser assisted endodontic procedures. It is based on the emission of a couple of consecutive laser pulses, where the second subsequent laser pulse shoots into the liquid at an optimal delay time from the first pulse, when the initial bubble is in the final phase of its collapse. This phenomenon produces an acceleration in “Laser induced bubbles” collapse leading to the emission of shock waves in narrow root canal. Another contemporary technique uses Nanobubbles (NBs) which are gas filled cavities within the liquid with a diameter of 1-200 nm. Due to their minimal size, these bubbles will not burst quickly after formation at the liquid surface, but rather remain in the liquid and burst in it. They are stable and can maintain their size in liquid for months. NBs water can potentially be added to endodontic irrigants and medicaments to enhance their tubular penetration capacity and in isolation, they do not have any direct bactericidal properties. This poster aims to highlight the avant garde technologies in irrigation which have brought about a paradigm shift in the approach towards root canal sterilization.

Seal the deal with SealBio

Gaurav Rawat

Government College of Dentistry, Indore, Madhya Pradesh, India

For the management of pulp and periapically involved teeth, “SealBio,” a novel, non-surgical endodontic treatment protocol based on “regenerative concept,” has been developed. The closure of the root canal system at the apical and coronal ends of a disinfected root canal is thought to be one of the crucial requirements for the successful completion of endodontic treatment. The ultimate goal, even with traditional gutta percha obturation, is to create a cemental/fibrous barrier at the root apex. A unique therapeutic strategy was developed to handle non-vital adult teeth with periapical disease by utilizing this method of promoting tissue healing and regeneration and combining it with comprehensive root canal system disinfection. As a result, “SealBio” should be preferred over an artificial barrier made of sealer and gutta percha cones at the apical end of the root canal system in order to achieve a biological seal.

Specialized pro-resolving mediators: Novel approach for reprogramming of pulpal inflammation

A. Jinesh

Government Dental College, Thiruvananthapuram, Kerala, India

Endodontic treatment success is linked to the prevention and healing of apical periodontitis. The most common factors implicated in the persistence of apical periodontitis are operatives. However, systemic factors such as an impaired immune response or a proinflammatory state may also be to blame for the lack or delay in resolution. Proresolving lipid mediators are endogenous inhibitors of particular stages of the inflammatory process (specialized molecules-SPM). They function as immune response modifiers, moderating and reducing the host response in a targeted manner while also promoting the healing of inflammation. Here is mounting evidence that SPMs are critical for the removal of debris and infectious agents, the alleviation of pain, and the prevention of infection. These substances have been researched in the context of systemic diseases. Treatment of pulpitis with topical SPMs within 24 hours of contamination was beneficial in controlling inflammation. Furthermore, SPMs administered within the root canals after disinfection were found to promote periapical healing. SPMs have the potential to play a role in the onset and treatment of pulpal-periapical diseases, and they should be considered for future research into developing new therapeutics to be used in conjunction with endodontic treatment.

Teflon: Tech with tact

Sanjana Jayakumar Nair

Sri Aurobindo College of Dentistry, Indore, Madhya Pradesh, India

PTFE (Teflon), also referred to as thread sealing tape, stands for polytetrafluoroethylene. The chemical nature of PTFE is [CF2-CF2] n. It is a linear polymer of tetrafluoroethylene [TFE]. PTFE has common uses outside of dentistry. Recently its use has been amplified in the field of conservative dentistry and endodontics because of its properties. PTFE is relatively inert, as such it is capable of resistance to solvents and acids, therefore will not degrade when used with dental etchants. This protects adjacent teeth during surface conditioning of treated teeth and also prevents the unwanted closure of approximal areas with luting agent. It has low static and kinetic coefficient of friction. It has high break elongation so it can be manipulated without the fear of tearing. It has a high melting point which allows the tape to be sterilized for dental purposes in an autoclave. So, teflon tape technique creates superb lucidity and visibility, assuring a reliable and easy workflow. This provides the adhesive working dental practitioner with an additional and efficient technique that can be easily included in daily practice.

Conserve dentition with endodontics rather than replace them with implants

Megha Ghosh

Triveni Institute of Dental Sciences, Hospital and Research Centre, Bodri, Chhattisgarh, India

Endodontic treatment helps in maintaining natural dentition associated with pulpal and periradicular diseases. Whereas, Dental Implants are therapeutic advancement in the replacement of lost dentition. Controversies regarding endodontic treatment of compromised teeth to preserve natural dentition or extraction and replacing it with dental implant is a clinical dilemma. Privileges of conserving natural dentition hints at preserving damaged natural tooth with endodontic treatment which helps in maintaining physiologic biting forces, alveolar ridge integrity, natural physiology, better mechano-reception of teeth and esthetics. However, with implants currently showing impressive rates of success, some clinicians aggressively indulge in extracting compromised teeth followed by implant placement as easy shortcut mainly due to excessive commercial emphasis on dental implants even for endodontically treatable teeth. But extraction has detrimental effects on human psychology so patients tend to delay the treatment. As natural is always superior to artificial, implants tend to lose bone support over years. Though dental implants are an excellent treatment modality, but it must be kept in mind that it is associated with the risks of biological and technical complications. Implants are supposed to replace the missing teeth; not replace teeth. Thus, judicial decision and systematic treatment planning should be made to favour predictable and long-term prognosis of treatment. Thus, the purpose of this poster is to enlighten the rationale of conserving, restoring and preserving the natural dentition through endodontic treatment of compromised teeth, rather than to deliberately overlook the prospects of saving the teeth by opting for extraction followed by an implant.

Sweeps to sweep the canal

Debarun Pal

Haldia Institute of Dental Sciences and Research, Haldia, West Bengal, India

During root canal therapy, complete removal of soft tissues and debris and complete eradication of bacteria remains a difficulty. Due to the complex nature of root canal morphology, canal preparation leaves untouched areas and develops hard tissue debris, which can become trapped in root canal irregularities, fins and isthmuses, preventing proper cleaning and disinfection. Irrigation is an essential part of root canal treatment as it allows for cleaning beyond the instruments. No irrigating solution, individually or in combination till date has proved to be 100% efficacious. Thereby, to bring the irrigants with direct contact of the root canal walls, various irrigation activation devices have been proposed. Laser Activated Irrigation (LAI) has become a potent activation technique of irrigants which involve the formation of vapor bubbles at the fiber tip that expand and then collapse. Recently, a novel Shock Wave Enhanced Emission Photoacoustic Streaming (SWEEPS) technology was developed to increase the cleansing and disinfection efficiency. The SWEEPS irrigation process amplified pressure waves more than the traditional Photon-Induced Photoacoustic Streaming (PIPS) irrigation process, which only emitted a single Er:YAG pulse. The aim of this review poster is to offer the most relevant data on a novel SWEEPS technology, its relative advantages, with an emphasis on single-pulse SSP laser assisted irrigation and dual pulse SWEEPS technology, as well as to provide recommendations for the use of SWEEPS technology in Endodontics based on current evidence.

Pulp for a pulp

Suman Bhattacharya

Haldia Institute of Dental Sciences and Research, Haldia, West Bengal, India

Autotransplantation is defined as the extraction of an erupted tooth from one part of the mouth and its placement into an extraction site or a surgically prepared recipient site in the same individual. Entire tooth autotransplantation of the third molar is a well-known and established procedure for the replacement of defective molars requiring extraction. Similarly, pulpal autotransplantation has been attempted in recent times where healthy pulp collected from erupted tooth has been placed in the instrumented nonvital tooth to regenerate pulp-like tissue with vascularity. Several advantages are included when performing pulp tissue autotransplantation, such as no risk of transplant rejection, having the same DNA and RNA, the presence of completely mature connective tissue and a formed neuronal network with previously built vascularization. These factors may enhance the success of pulp regeneration using minced pulp as a source of mesenchymal stem cells to provide odontogenic differentiation. Furthermore, in vivo clinical regeneration of pulp tissue would be faster than using only scaffolds, mesenchymal stem cells, and growth factors. For a successful clinical procedure of pulp autotransplantation, atraumatic extraction of a third molar is of prime importance. The Doppler ultrasonic evaluation is used to confirm apical revascularization. Future studies should focus on the possible assessment of pulp transplantation among people from different families and a feasible test to confirm the gene compatibility for such a novel form of transplantation. This poster aims to summarize these concepts and their recent development to be applied in clinical practice.

Human three-dimensional dental pulp organoid model for toxicity screening of dental materials on dental pulp cells and tissue

Kranti Rajesh Khadse

New Horizon Dental College and Research Institute, Bilaspur, Chattisgarh, India

For new biocompatible materials used in Restorative Dentistry and Endodontics, cytotoxicity screening as says are required to assess their biological safety before clinical use. Cytotoxicity screening assays provide a measure of cellular reactions to materials or their extracts. In vitro monolayer cell cultures have been utilized extensively as an efficient and economical tool in screening dental materials. Biocompatibility evaluation using in vitro monolayer cell culture models is not always consistent with results from in vivo animal biocompatibility evaluation. These interpretational difficulties have provided the impetus for improving the current use of in vitro cytotoxicity assays. Three - dimensional (3D) cell culture systems seen more promising due to higher levels of cell differentiation and tissue organization, closely resembling human tissue and organisms, where cells are anchored in a complex 3D extracellular matrix (ECM). The advanced 3D models are organoids, which are 3D miniaturized representations of selected tissues within a dish. The 3D organoid technique has been used in tissue engineering for many types of organs and drug screening. In addition, 3D functional organoids can also be used for studying dental pulp disease or regenerative endodontic therapy. Compared with monolayer dental pulp cells, 3D dental pulp organoids can establish intercellular interaction and are more resistant to external stimuli.

Digital impression in operative dentistry

Tanaya Badyakar

Haldia Institute of Dental Sciences and Research, Haldia, West Bengal, India

Digital technology now offers an alternative approach to conventional impressions for appliance fitting and manufacture. In digital impressions digital image of the patient's teeth can be created with the use of intraoral scanners. Hence the need for making impressions is eliminated. Therefore, less chairside time is required. Clinical studies have proven that the fit of the indirect restorations is more accurate with digital impression compared to traditional impression. Main drawback of the technology is high investment cost for hardware and the implementation requires time. The digital image of the prepared tooth is recorded intraorally with a scanner wand. After scanning, the dentist can review the digital image to confirm that the required areas are captured and sufficient occlusal clearance is present. The data can be electronically transmitted to a dental lab along with instructions once the dentist is satisfied with the prepared tooth and scanned digital images. The dental laboratory or its manufacturing partner receives the scanned images, later utilizes a specialized software to identify the margins of the prepared tooth, then digitally marks and does die trimming. Computer-aided design/computer-aided manufacturing (CAD/CAM) is a technology that enables single session indirect restorative procedure. A 3-dimensional (3D) printed or milled model is obtained by the laboratory, which can be used for fabricating the desired restorations. The rapid milling process minimizes the waiting time between the preparation and cementation of restoration.

Newer advances in dental matrices – Temporary walls for permanent solution

Vaishali Shukla

Triveni Institute of Dental Sciences, Hospital and Research Centre, Bodri, Chhattisgarh, India

For long-term survival of dental restorations functionally and esthetically, certain considerations are very critical for maintaining the health of the tooth and periodontium; thus due importance is needed to maintain a proper contact and contour of restorations without gingival overhangs in clinical restorative practice. But, achieving tight anatomical and proximal contacts remains difficult when placing restorations. In this context, the choice of the matrix systems becomes an very important factor. Dental matrix systems are used for 3 things; Recreating the interproximal contacts for natural tooth shape and contour, Sealing the gingival and proximal walls of the preparation and Overcoming the thickness of the matrix band. Dental matrix systems are placed to establish a temporary wall of a tooth during the restorative procedures. To overcome some of the disadvantages of Conventional matrix systems, Various modifications are done in improving their design and precision, thus making them easier and quicker to place, great at conforming to the size, shape and contours of the teeth, easy to burnish, better adaptability and comfortable to the patient and most importantly, these newer modifications in matrix systems helps in establishing natural tooth contact and contours. Selection of a proper matrix system is essential for successful proximal restorations. The choice of matrix systems by the clinician reflects to their level of knowledge and skills about the placement techniques of these newer matrix systems. The objective of this Poster presentation is to apprise about the Newer advances in Dental matrices.

Guided endodontics – Paving its way through the obstacles

K. Sushma

D A Pandu Memorial R V Dental College, Bengaluru, Karnataka, India

The aim is to discuss the use of guided technology in endodontics, particularly in calcified canals and also the amount of tooth structure loss by the use of this technology. Endodontic treatment of teeth with canal obliteration poses a challenge given the higher chances of procedural errors and complications during treatment. This is possible by a combined approach of Cone Beam Computed Tomography (CBCT) and intra-oral scan which can be used to design a personalized 3-D printed intra-coronal guide for the patient. Although, at present, conventional access cavity preparation combined with CBCT in cases of pulp canal obliteration is followed, it leads to high loss of dental hard tissues. Hence, guided endodontics provides a highly accurate technique for the preparation of minimally invasive cavities. This poster concentrates on the clinical applications, the operative steps in endodontic cases, the recent techniques and also gives a perception about the current and future aspects of this guided access technique in endodontics.

Biomimetic restorative dentistry – The nature inspired way

Saloni Sinha

D A Pandu Memorial R V Dental College, Bengaluru, Karnataka, India

Biomimicry involves studying nature's most successful developments and then imitating these designs to create new materials. Biomimetic dentistry is the art an science of restoring damaged teeth with restorations that mimic natural teeth in appearance, function and strength. Although commercially available restorative materials have great esthetics and good mechanical properties, the durability of restoration is threatened by the occurence of inadequate strength, increased solubility and weaker adhesion to tooth structure. The biomimesis seems to be a promising approach for both enamel and dentin remineralisation. Biomimetic dentistry is an interdisciplinary approach and has potential for transforming everyday dental practice. This poster concentrates on different biomimetic materials, their recent advances, the mechanism of biomimicry and give an insight about the current and future perspectives of the biomimetic dentistry.

Simulation of human intelligence: Artificial intelligence in endodontics

Gaurav Deore, Mohammed Ahmed Ali Khan

Rungta College of Dental Sciences and Research, Bhilai, Chhattisgarh, India

Artificial intelligence (AI) is a branch of applied computer science that was first described by John McCarthy in 1956. AI uses computer technology to simulate intelligent behavior, critical thinking, and decision making similar to humans. AI can assist in the development of algorithms that can learn from information provided and make predictions. Two types of AI are available, physical and virtual. Physical applications are represented by sophisticated robots or automated robotic arms. Virtual components are software-type algorithms that support clinical decision making. AI have been used in endodontics mostly by virtual employment such as the detection of periapical lesions, crown, and root fractures; working length determination; and morphology detection. These procedures describe the virtual aspect of AI. AI systems have the potential to revolutionize the field of Endodontics by identifying solutions in managing multiple clinical problems that have also made Endodontist's tasks easier. There is a need for high quality evidence to evaluate the performance of AI regarding its reliability, applicability, legal and ethical considerations, and cost effectiveness before widespread adoption into routine clinical practice. Artificial intelligence can help make considerable advances in providing better health care to patients, but it will never be able to replace human knowledge, skills, or judgement.

Pregnancy in endodontics

Sariya Varun Damodarbhai, Chitroda Bhargav Yogeshkumar

Government Dental College

The purpose of this poster is to update general dentists and endodontists in the perioperative management of the pregnant patient. Odontogenic pain affects up to 54.9% of pregnant women. This pain is often associated with pulpal and/or periapical infections which pose risks to women and their foetus. A recent survey reports that up to 43% of pregnant women experience oral health problems including odontogenic pain and infections. These infections pose a risk to women and their foetus; for example, spread of infection from a mandibular second molar may result in Ludwig's angina, a known risk factor for maternal and foetal morbidity. It states that dental treatment can be rendered safely to pregnant women during all trimesters. However, many dental providers avoid delivering oral health care during pregnancy. This can be partly attributed to lack of consensus about the safety profile of medications, as well as fear of litigation. Lack of clarity of the FDA risk categories and limited knowledge of the safety of medication, Radiograph, Ergonomics, Local Anaesthetic, & other pregnancy related conditions may result in avoidance of endodontic treatment during pregnancy. The taboos and myths regarding dental care during pregnancy are still present among pregnant women and health professionals, including dental professionals. It is necessary to continue spreading knowledge for the development of new health policies that increasingly include dentistry during pregnancy, favouring the health of women and their children.

Magnification in endodontics

Kalantri Sarika Sunil

Saraswati Dhanwantari Dental College and Hospital, Post Graduate Research Institute, Parbhani, Maharashtra, India

Dentistry has become more sophisticated and complex thus requiring precised motor skills and visual acuity. Optical magnification has expanded the horizons of dentistry. The advent of micro dental treatments has made necessary that dentists improve the visual acuity of the operating field to diagnose early and to treat those areas with greater accuracy. The use of magnification devices in dentistry enhances visualization and improves ergonomics. Various alternatives in the use of magnification exist for all clinicians from introductory magnification systems, like single lens loupes, to high powered dental operating microscopes. A tremendous opportunity exists for all the clinicians to drastically improve their vision by use of magnification and illumination. Traditional endodontics has been based on feel not sight. Since the endodontic surgical field is measured in millimeters, endodontic therapy has always been very dependent from the tactile sensation of the operator and its anatomic knowledge. The use of magnification in dentistry appears to be of increasing interest. With the recent advances of magnification devices with increased magnification and illumination there is improved technical accuracy and performance. Now the use of such magnification systems is a very popular practice in dentistry as well. There are three principal reasons for adopting magnification for operative dentistry and endodontics: to enhance visualization of fine detail, to compensate for the loss of near vision (presbyopia) and to ensure maintenance of correct posture.

To crown or not to crown root canal treated teeth?

Ejaz Ahmed

SDM College of Dental Science and Hospital, Dharwad, Karnataka, India

Endodontic therapy has a success rate up to 86-98%. However, a successful endodontic treatment does not depend only on a good root canal therapy, but good restorative treatment is crucial. Completing the root canal treatment is not the end of the story, the tooth needs to be restored back to normal function, form, and aesthetic. The quality of the final restoration has its effect on the survival and success rate of endodontically treated tooth. Root canal treatment through cleaning, shaping and apical sealing are crucial for periapical healing. Moreover, Coronal restoration of the root canal treated tooth is required to prevent coronal leakage and to provide function and aesthetic. The quality and timing of the final restoration has its effect on the survival and success rate of endodontically treated tooth. It has been found that full coverage restorations show a higher long-term survival rate than direct restorations. Long term survival is the main criteria of successful endodontic treatment. Full coverage restorations show a higher survival rate than direct restorations. The definitive restoration should be placed as soon as RCT completed. It has been shown that time of crown placement after endodontic treatment affect the survival rate of endodontically treated teeth. Finally, no need for a post if the remaining tooth structure can withstand the core material. This poster is intended to add light on whether to crown or not to crown endodontically treated teeth.

Separated root canal instrument – Leave, bypass or retrieve?

Thanima Chandran

Dr. Rajesh Ramdasji Kambe Dental College, Akola, Maharashtra, India

With an increased practice of rotary endodontics in recent years separated rotary nickel-titanium (NiTi) files in root canals is the most commonly reported mishap, causing lot of stress and anxiety among clinicians and patients. No clear guidelines can be drawn from the literature available, because there are either too few studies about the effects of broken files on prognosis or few studies that have been performed on patients. The prognosis is also dependent on file location, prior condition of the pulp, presence or absence of periapical lesion and many other factors. Intracanal separation of endodontic instruments may hinder cleaning and shaping procedures within the root canal system with a potential impact on the outcome of treatment. The incidence rate of instrument separation for stainless steel instrument ranges between 0.25% and 6%. The purpose of this poster is to put an insight on whether to bypass or retrieve a separated instrument and the management of separated intracanal instruments. The main objective of root canal treatment is complete debridement and uniform shaping of the root canal system.There are many procedural errors commonly faced by the clinician in a day-to-day endodontic practice. However, separated endodontic instruments serves as a stumbling block in achieving this objective. It is an unfortunate occurrence that may hinder root canal procedures and affect the treatment outcome.

Endodontics requires radiographic imaging for diagnosis, treatment planning, therapy and follow-up. Dental radiography allows for the identification of pathologic changes in the periradicular tissues that cannot be visualized by clinical inspection. For precise execution of endodontic therapy, regular radiography verification of individual treatment steps in necessary. It is important to evaluate the normal and pathologic findings relevant to endodontics for the clinicians. Key radiographic imaging techniques, as well as horizontal and vertical eccentric radiography are discussed in this poster. The increasing utilization and impact of CBCT providing 3-dimensional volume imaging are also discussed in the present poster.

Microleakage says, “who will make me more invisible?”

Stuti Aggarwal

National Dental College, Dera Bassi, Punjab, India

Aim: Impetus of this study is to assess and compare microleakage of different composite restorative materials. Introduction: Resin based composites are undoubtedly the materials of preference in contemporary restorative dental practices, due to their mounting quest for superior esthetics. However, the main problems associated with composites is their stress concentration & polymerization shrinkage. Errors encountered in placing manifold layers can result in shrinkage & hence microleakage, which results in seepage of oral microbes, saliva & other organic components through the tooth restoration interface resulting in dentinal hypersensitivity & pulpitis. Materials and Methodology: Standardized class 2 cavities will be made on 30 sound molars having approximately 4 mm of width & 2 mm gingival extension below CEJ. Samples will be categorized in group of three (n=10) based on composites used. Prepared cavities will be filled with respective composites. Post thermocycling, specimens will be absorbed in 0.5% methylene blue for 8 hours & then soaking in tap water for 12 hours. Later the samples will be split in mesiodistal direction with a diamond disk at the center of restoration. The samples will be later viewed under stereomicroscope. Statistical Analysis: One way ANOVA & post HOC test will be used to derive statistical data. Results: Study in process.

Resin infiltration

Taha Siddiqui

Government Dental College, Raipur, Chhattisgarh, India

Fluorosis is an endemic disease characterized by excess deposition of fluorides in hard and soft tissues of the body. Dental fluorosis is a specific esthetic disturbance, which is described as a chronic condition, in which the ameloblast are disturbed leading to defective enamel formation which results in Enamel hypoplasia. Dental fluorosis is characterized by the presence of mottled enamel, brownish discoloration of teeth, pitted enamel, bilateral diffuse thinhorizontal white striations which are stained with plaque. The esthetic perception of mottled enamel across young patients may have considerable psychosocial effects and may impact their quality of life. Young pateints have a life expectancy of many decades hence, minimal-invasive, hard-tissue sparing restorative approaches such as microabrasion, external bleachingor resin infiltration have gained momentum. A novel technique for white spot lesions is recently developed which is infiltration of low-viscosity light-cured resins, whichcan inhibit demineralization and mask white-spot lesions showing good clinical applicability for clinicians and very high acceptance by pateints. These low-viscosity resins reduces visibility of white-spot lesions as they have a refractive index similar to that of enamel. Studies have proventhat resin infiltration with increased infiltration time or resin infiltration followed by bleaching or resin infiltration alone will provide a better esthetic results. The resin infiltration technique is a conservative approach that improves the esthetic appearance of white spots from mild to moderate fluorosis, masking them in a short interval of time with having a considerable stability.

Restoration of endodontically treated teeth with extensive coronal loss has always followed a strict protocol, with the fabrication of total crowns supported on metal cores and/or glass fiber posts. However, it has been observed that the use of intracanal retainers only promoted retention of the prosthetic crown. Removal of healthy dental structure to enable the placement of rigid elements devoid of mechanical behaviors similar to those of the tooth, will weaken the remaining tooth structure. Endocrowns are an appealing alternative, as restorative dentistry stands against the wastage of tooth tissue. Pissis was the forerunner of endocrown restoration. Endocrown are anchored to the internal portion of the pulp chamber and on the cavity margins, obtaining macromechanical retention by the axial opposing pulpal walls and microretention attained with the use of adhesive cements. The main advantage of endocrowns is related to the fact that it does not require root dentin removal in order to gain retention. The saddle shaped pulp floor in molars along with the quality of the adhesive materials provide good stability. The monoblock nature of endocrowns supports more stress loading than the multiinterfacial nature of conventional restorations. The supragingival margins facilitate plaque control, clinical inspection and preservation of periodontium with minimal involvement of the biological width.

Water expandable obturation system

Yash Motwani

Government Dental College, Raipur, Chhattisgarh, India

The sole purpose of obturation of root canals is to prevent re-infection of the canal space and ultimately prevent periradicular disease. This may be achieved by three-dimensional filling of the instrumented canal, accessory canals, and dead spaces. While different techniques are currently available to achieve this goal, there is on-going interest in developing simplified obturating materials/techniques for filling irregular-shaped canals and to minimize voids created during obturation procedures which may act as niduses for growth of residual biofilms. The CPoint system is a point-and-paste root canal filling technique that consists of pre-made, hydrophilic endodontic points and an accompanying sealer. The deformable endodontic point (CPoint) is available in different tip sizes and tapers and is designed to expand laterally without expanding axially, by absorbing residual water from the instrumented canal space and that from naturally-occurring intraradicular moisture. The lateral expansion of CPoint is claimed to occur non-uniformly, which depends on the contact of the hydrophilic polymer to the canal wall, expansion reduces as the polymer contacts the wall. This nonisotropic lateral expansion is said to enhance the sealing ability of the root canal filling, thereby reducing the possibility of re-infection, and potentiating the long-term success of root canal treatment.

Nanotechnology in endodontics

A. M. Sumayya Beevi

Government Dental College, Raipur, Chhattisgarh, India

Nanotechnology is defined as the study and use of structures between 1 nanometer and 100 nanometers in size. It is an emerging field that is undergoing rapid development and has brought enormous changes in the field of medicine and dentistry. Nanomaterial-based design is able to mimic some of the mechanical and structural properties of native tissue and can promote biointegration. Studies have demonstrated that nanoparticle-based materials have superior physical, chemical and biological properties compared to conventional ones. This leads to the addition of nanoparticles into the dental materials with the aim to enhance its various properties for predictable clinical outcomes. It has various application in the field of Endodontics. One of the common mishaps during endodontic therapy is instrument separation. It can be prevented up to a certain limit by modifying the surface of the endodontic instruments using nano particles. Nanoparticles based irrigants and medicaments have superior disinfecting capacity compared to the conventional ones. The smaller particle size of nanoparticles allows better diffusion into the unapproachable areas of root canals, which results in efficient disinfection. Nowadays, to improve the quality of endodontic therapy manufactures have started to incorporate nano particles into sealers, obturating matertials and retrograde filling materials. Polymeric nano-biomaterials can be used as nano-scaffolds for the regeneration of the pulp. These scaffolds provide mechanical support to stem cells. Nano hydroxyapatite can be used as a substitute for direct pulp capping agents. It produces complete dentinal bridges and has favourable cellular and vascular response.

Ozone in aerosol free endodontics – Post COVID-19

Riddhima Chauhan, Abhishek Kumar

Faculty of Dental Sciences, PDM University, Bahadurgarh, Haryana, India

On January 30, 2020, the WHO designated the Corona virus outbreak a public health emergency of global concern. The danger of cross infection between patients and dental professionals can be substantial due to the peculiarities of dental environments. To reduce aerosol discharge and lower patient and dentist exposure, many treatment option adjustments have been researched.

Modern endodontic access cavity design

Siddhi Alok Dhadda

Mahatma Gandhi University of Medical Sciences and Technology, Jaipur, Rajasthan, India

Every endodontic treatment aims to eradicate all organic substrates from the complex root canal system and to obturate the root canal system. After the establishment of a diagnosis and treatment plan, the next step is access cavity preparation. Access cavity preparation is of paramount importance as it is the vital stage that governs the success or ease of the subsequent treatment stages. With enhanced magnification and the availability of flexible nickel-titanium rotary instruments, there has been a paradigm shift in endodontics from conventional to conservative access preparation. The application of conventional access cavity preparations became questionable as it is invasive and may lead to structural failure of a tooth. It is found to be one of the largest causes of failure of root canal treatment. The critical zone is the pericervical dentin which is irreplaceable as it plays a critical role in the maintenance of long-term survivability and optimum function of endodontically treated tooth and also helps in the prevention of fracture, and preservation the ferrule. So, a reduced endodontic access design would reduce the failure of root canal treatment. With unparalleled advancements in technology and materials over the past decades. This era has witnessed remarkable development in endodontic technologies, bringing about various modifications in all phases of endodontic treatment, including access opening.

Dental composites: Challenges and upcoming strategies: An insight


Educare Institute of Dental Sciences, Chattiparamba, Kerala, India

The increasing demand in the field of aesthetics and advancements in restorative materials has made widespread use of dental composites, an inseparable part of restorative dentistry. The trend of using resin-based dental composites instead of amalgam is increasing in dentistry due to its minimally invasive intervention, adhesive property, ease of manipulation and command set. Despite many signs of progress in the performance of resin based composites, their durability and longevity as dental restorations are limited. One of the major limitation of resin composite restorative materials is the polymerization shrinkage which leads to marginal leakage, secondary caries and discoloration of the tooth. Other limitations which are of major concern include the human exposure to monomer residues (bisphenol-A, a carcinogen), C-factor and placement technique which can affect the microtensile bond strength of the adhesive system. To overcome these problems many methods like incremental technique, staged cure techniques had been implemented. This poster will enlighten on newer methods for enhancing the properties by modifying the organic resin matrix like methacrylate monomers having bulky bicycloaliphatic rings, vinyl monomers utilizing allyl group, click chemistry-based resin system using thiol-X reactions, and ring-opening polymerizing monomer systems containing spiro-orthocarbonates and siloranes which enhances longevity due to reduction in bullk/marginal fracture and secondary caries by reduced polymerization shrinkage related stress and strain. The introduction of bio-based monomers with new structures for the replacement of conventional monomers is of great importance to limit the health-related risk of dental composites.

Guided endodontics

Avneet Kaur

Mahatma Gandhi University of Medical Sciences and Technology, Jaipur, Rajasthan, India

Endodontic treatment with pulp canal obliteration is challenging as firstly the search for a calcified root canal can be very time-consuming and is associated with an increased risk of technical failures including alterations of root canal geometry and extensive loss of dental hard tissue, which may cause weakening of tooth or creating a perforation. With the current traditional armamentarium of management of obliterated canals using burs, orifice openers etc under magnification, a novel approach such as 'Guided Endodontics' has been introduced as an alternative to conventional access cavity preparation. It is beneficial in producing a minimally invasive access cavity and locating calcified root canal, using a special software alignment with CBCT and surface scans for virtual planning. Subsequently, a template is produced by means of a 3D printer for guiding a minimally invasive drill to calcified or narrow root canal to achieve predictable and safe results. This concept could help clinicians during treatment by avoiding unnecessary tissue removal, iatrogenic errors and post-operative inconveniences of endodontic microsurgery, therefore, improving the prognosis of treatment. The purpose of the poster is to introduce a new surgical endodontic technique by using a three-dimensional printed template for various surgical procedures. In this poster, the indications, procedure, merits and demerits of 'Guided Endodontics' will be highlighted.

G Pulla Reddy Dental College and Hospital, Kurnool, Andhra Pradesh, India

Separation of root canal instruments is a common incident during root canal procedures. This complication can have an enormous impact on the outcome of the treatment, can be an obstacle for the proper cleaning, shaping and definitive obturation of the Root Canal System, therefore can be the reason for a future endodontic failure. When an instrument fracture occurs during root canal preparation procedures, the clinician has to evaluate the treatment options with consideration for the pulp status, root canal infection, root canal anatomy, the position and type of fractured instrument and the amount of damage that would be caused to the remaining tooth structure. The removal of the broken fragments with traditional methods is time consuming, risky and has limited success. The fractured instrument was successfully and safely retrieved using different procedures and techniques including bypassing the fragment to loosening the fragment using ultrasonics. One of the recent advances in broken instrument retrival is micro dental tweezers. This poster will highlight how micro dental twezzer is effective in removal of broken instruments.

Revive your restoration with a hint of tint

Ashna, Nireksha Nirmal

Buddha Institute of Dental Sciences and Hospital, Patna, Bihar, India

Creating lifelike restorations that harmoniously complement existing dentition is every dentist's goal. Considering the major role composite restorations play in clinicians' daily practice, mastering this technique is vital. Simply using the resin is not enough—it also is essential to characterize the restoration through the artful application of additional colors or tints. Tints helps us to successfully mimic nature to produce realistic and esthetically pleasing results that meet patients' needs and desires. A slight tint can go a long way. We look at the advantages of using tints, the indications for their use, and some dos and don'ts with this less-is-more material. We can mimic surface defects like pit and fissure staining, recreate craze lines to match the patients' other teeth, match unusual colors, or imitate cervical darkening. Tints are also excellent for recreating incisal translucency. Using tints is comparable for artistic effects in esthetic restorative work to applying women's makeup. When you don't notice all the work that the makeup artist has done with all the different colors and materials on their face, that's when the makeup makes the person look amazing. Avoiding too much symmetry and adding faint enhancements and characterizations so that tint work is not noticeable is what required. When something looks too symmetrical, and everything looks the same across the smile or a tooth, it looks artificial. Recreating these subtle imperfections is essential to this realism and that is what tints do.

Micro-RNA – An innovational approach?

Lekshmi Chandran

Government Dental College, Vijayawada, Andhra Pradesh, India

Root canal therapy aims to reduce microbial infection and restore an aseptic environment to minimize apical lesions and promote bone healing. However, persistent apical periodontitis occurs when endodontic treatment has not adequately eliminated the infection or when reinfection occurs because of inadequate coronal seal or microleakage. Recent research advances have provided numerous molecular targets and endodontic techniques that may ease the development of biomarkers in early diagnosis and the translation of novel therapeutic tools to promote apical tissue regeneration. Among these targets, microRNAs as a class of novel molecules have recently emerged as essential regulators of these processes, and their therapeutic values have just begun to be appreciated. MicroRNAs are small, noncoding RNA molecules that play pivotal roles in the post-transcriptional modulation of gene expression. Based on their abundance, prolonged stability, and relative ease of sampling, miRNAs may be a useful tool to be developed as diagnostic biomarkers in apical periodontitis and also for predicting the prognosis for vital pulp therapy. This concept can also be used for non-surgical and surgical treatment planning, this will greatly enhance the informed decision-making process. Similar to the idea of biomarkers, miRNAs can also be designed as therapeutic targets. Micro-RNA products may be distributed via intracanal delivery using a microcannula or by local infiltration using a syringe during non-surgical root canal treatment or by direct application during apical surgery. Currently, several miRNA-based therapeutics are undergoing clinical trials targeting dental stem cells which could revolutionarily change the future of regenerative endodontics.

Bonding mechanism of metal free restorations

Nayanika Chatterjee

Buddha Institute of Dental Sciences and Hospital, Patna, Bihar, India

Metal free restoration has emerged as a substitute to Ceramic restoration, in response to patients' esthetics growing demand. Due to inherent brittleness, the behaviour of ceramics in the oral cavity under functional stress is very different from metals. Excessive forces and surface damages may lead to fractures and cracks. Adhesive bonding with composite resins and proper treatment of the abutment tooth and the ceramic bonding surface increase fracture resistance of ceramic restorations, improve retention, and reduce microleakage. Clinical and laboratory bonding protocols depend on the type, composition, and properties of the ceramic. Silica-based ceramics (eg, feldspathic, leucite-reinforced, and lithium silicate) should always be resin-bonded and treated with acid-etching and silane coupling-agent application, combined micromechanical and chemical pretreatment is necessary for long-term durable resin bonds to zirconia. Air-particle abrasion has to be done with Al2O3 and then treated with 9%hydrofluroic acid for 60 seconds which is then air dried. After etching with phosphoric acid then adhesive system are applied to the preparation and ceramic surface. The light-cured cement is inserted and spread all over the fitting surface of the veneer and pressed digitally. Finally, finishing and polishing with abrasive strips and rubbers are done. This poster provides an insight into the benefits and technique of bonding procedure as they provide the best possible long-lasting esthetic and functional outcomes.

Challenges in vital pulp therapy

Jayanti Prabha

Dr. R Ahmed Dental College and Hospital, Kolkata, West Bengal, India

Vital pulp therapy (VPT) is defined as “a biologic and conservative treatment modality which aims at preserving and maintaining the vitality and function of the coronal and remaining radicular pulp tissue in permanent teeth that has been compromised but not destroyed by extensive dental caries, trauma, restorative procedures or for iatrogenic reasons.” VPT offers beneficial advantages over the conventional root canal treatment such as protective resistance for mastication forces or to prevent the loss of ability to sense environmental changes, that later leads to unnoticeable progression of caries and fracture. VPT procedures involve removal of local irritants and placement of a protective material directly or indirectly over the pulp to promote the pulp tissue healing. Pulpotomy has long been the most indicated vital pulp procedure in primary molars with extensive caries. The query about the exact indications and contraindications of VPT in permanent teeth has never settled down because it involves multiple factors such as understanding the complex nature of the carious disease, knowing the pathological state of the pulp and recognizing the capabilities and limits of biomaterials in stimulating repair. The presence of microorganisms with subsequent infection, in?ammatory status of the pulp tissue, the size and duration of carious pulpal exposure pose challenges to VPT. Location and quality of the dentin bridge, the type of pulp therapy material used and the technique employed are the criteria used to determine success and prognosis of VPT.

Vishnu Dental College, Bhimavaram, Andhra Pradesh, India

Guided endodontics (GE) is an innovative approach to managing challenging treatment modalities like obliterated root canals, minimal invasive root-end surgeries and conservative access cavity preparations. Static-guided endodontics involves the fabrication of computer-generated 3D printed guides using CBCT images, digital surface scans and virtual planning software. Static guides have limitations, such as difficulties being employed in posterior teeth due to restricted inter-occlusal space, despite the great accuracy. The dynamic navigation system (DNS), a distinct technique adopted from implant dentistry, has been used for both surgical and non-surgical endodontic therapies. Using an optical tracking device managed by a special computer interface, DNS combines CBCT and spatial positioning technologies. Based on the pre-operative plan, clinical real-time navigation directs the clinician to provide a specified path for the target site. With the introduction of Augmented reality in neurosurgery, clinical execution in endodontics has been advocated but has not yet been implemented on the clinical side. AR navigation might be the next step in simplifying and enhancing the clinician experience with dynamic navigation. The AR approach overlays virtual images such as radiographs and navigation paths on the user's vision of the real world with a view of the operative field in a head-mounted display or a dedicated microscope. This poster aimed to provide brief information regarding the evolution of GE from static guided endodontics to AR through a dynamic navigation system aided to preside over challenging treatment procedures in the field of endodontics.

Nanotechnology describes the science and technology related to the control and manipulation of matter and devices on a scale less than 100 nm.The practical application of nanotechnology in endodontics has led to the future prospectus in research in this field. As a result of their nanoscale dimensions, nanoparticles possess several properties that may enhance the treatment of endodontic infections such as heightened antibacterial activity, increased reactivity and the capacity to be functionalized with over reactive compounds. Effective disinfection and sealing of the root canal system are the hallmarks for successful endodontic treatment. However, the presence of bacterial biofilms and resistance to endodontic disinfectants pose a significant challenge to this goal. This has encouraged the investigation of antibacterial nanoparticle-based irrigants and intracanal medicaments, which may improve the elimination of endodontic infections. In addition, photosynthesizer –functionalized nanoparticles could also serve as a trust worthy adjunct to root canal disinfection strategies. Various experimental nanoparticle-incorporated obturation materials and sealers that exhibit a range of favorable physicochemical properties including enhanced antibacterial efficacy and bioactivity have been discovered. Nanoparticle applications also show promise in the fields of regenerative endodontics, such as supporting the release of bioactive molecules and enhancing the biophysical properties of scaffold.

Over instrumentation during root canal treatment is one of the cause for iatrogenic enlargement of the root apex. It leads to, thinning of the dentinal walls and makes the tooth susceptible to fracture. Another difficulty arises are control of obturation material within the canal and proper three dimensional seal of obturation material. This all factors along with microbial, mechanical, or chemical invasion contribute to pulpal and periradicular pathosis. So, the goal of the treatment is to obtain a fluid-tight seal at the apical extent to preserve from the irritants. Currently there is a paradigm shift in the management of such cases from traditional surgical procedures towards non-surgical apexification procedures using artificial apical barriers. This case report describes the treatment and a year follow-up of the teeth with large periapical lesion using MTA as apical filling material.

Direct and indirect composite techniques

Dineshkumar Chavhan

Dr. Hedgewar Smruti Rugna Seva Mandal Dental College and Hospital, Hingoli, Maharashtra, India

Increase in demand for esthetics has led to the development of tooth-colored, nonmetallic restorations such as direct composite restorations, indirect composite inlays, and ceramic inlays or onlays. Recently, there has been increase in the use of resin composites in dentistry. In addition to being esthetic, these materials are relatively less expensive, induce lesser wear of opposing tooth structure and are based on the principle of minimally invasive procedure. There are different techniques for placement of composite resin restorations. It includes direct and indirect technique. In direct technique, following etching and application of bonding agent to the prepared cavity, composite restoration is built up in increments, curing one layer at a time. Indirect technique refers to fabrication of the restoration outside the oral cavity in the laboratory following which it is luted to the tooth with resin cement.

Neelam Chandwani Bajaj

All India Institute of Medical Sciences, Nagpur, Maharashtra, India

Objective: To compare the in vitro antimicrobial efficacy of babul, Sodium hypochlorite and Chlorhexidine on E-faecalis, S. aureus and C. albicans and assess their efficacy in disinfecting contaminated GP cones. Secondary objective was to verify the sterility of sealed GP cones.

Materials and Methods: The antimicrobial efficiency of 3% sodium hypochlorite, 2% Chlorhexidine, Babul and Saline was assessed against E-faecalis, S. aureus and C. albicans using agar well diffusion technique (Kirby-Bauer method). Total 120 GP cones were cut into 3 parts with a sterile GP cutter. The upper part of gutta percha cone was directly placed into nutrient broth to assess its sterility by checking turbidity. The second part of GPcone was first contaminated for 30 seconds and then placed into nutrient broth to evaluate turbidity. The third part of GP cone was contaminated and then placed into experimental disinfectants for 5minutes. Antimicrobial effect was evaluated by observing turbidity. Statistical analysis was performed using unpaired t test and chi square test at a significance level of p< 0.05.

Results: 2% Chlorhexidine showed maximum antibacterial action against E. faecalis and S. aureus followed by Babul herbal extract. 2% Chlorhexidine was found to be more effictive in decontaminating GP cones followed by Babul and 3% Sodium hypochlorite in 5 minutes. Conclusions: Babul extract showed antibacterial action and comparable efficacy in decontaminating gutta percha cones. Hence itcan be considered as alternative to chemical disinfectants for disinfection of GP cones.

File dissolution via an electrochemical process

Saakshi Agarwal

Rama Dental College, Kanpur, Uttar Pradesh, India

The retrieval of fractured instruments from root canals has been largely reported in the literature. Mechanical methods to remove fractured instruments are strongly dependent on professional ability, and most of the time the use of an operating microscope is necessary. However, a less complex retrieval method that causes minimum damage to the dental structures is needed. In this poster, a new concept of retrieval of fractured instruments from root canals based on an electrochemical process will be discussed. The method includes filling the root canal with a solvent (electrolyte) and dipping two electrodes: anode & cathode. An anode is placed in contact with a separated instrument. The voltage difference between the electrodes causes the flow of electrons from the anode to the cathode, resulting in the progressive release of metallic ions from the separated instrument to the electrolyte & hence, its dissolution.

Minimalist approach to access cavities

Minimalist approach to the access cavities: Less is the new more

Sonal Sonawane

Dr. Hedgewar Smruti Rugna Seva Mandal Dental College and Hospital, Hingoli, Maharashtra, India

Access cavity preparation is the key step during a successful endodontic procedure. Inadequate access cavity preparation may interfere with the goal of the endodontic therapy which is complete disinfection, cleaning & shaping, and obturation of the root canal. Traditional access cavity designs have been established several decades ago based on the objectives which include removal of caries, deroof the pulp chamber, locating all of the canal orifices, and establishing straight-line access to the canals while also conserving the remaining tooth structures. Minimal invasive access cavity preparation has become a new trend topic in endodontics with advancements in the technologies. The trend began based on publications from Clark and Khademi which states that “the traditional approach to endodontic access is fundamentally flawed”. It is proposed in the field of endodontics with the aim of preservation of the pericervical dentin. Preservation of the pericervical dentin may improve the fracture resistance of the endodontically treated teeth. Minimally invasive access cavity preparation for the preservation of the tooth structure may compromise one or more objectives of the access cavity preparation which have been achieved by the traditional access preparation over the decades. So the vision of this poster is to present the recent advances in minimally invasive access cavity preparation and compare them with traditional access cavity preparation.

Newer modalities for managing the curved trajectories to reach the terminus

Drisya D. Nambiar

Mahe Institute of Dental Sciences and Hospital, Mahe, Kerala, India

Instrumentation of straight canals have always shown better results. Unfortunately, most of the canals in human dentition are curved. Shaping of these canals increased the risk of procedural errors which includes transportation, ledges, perforation, instrument separation, asymmetrical dentine removal and alteration of internal anatomy all of which effects the prognosis of the treatment. In the absence of curvature, conventional stainless steel files have shown favourable results, later the innovation of newer Ni-Ti files provided greater security and adaptability for handling curved canals. The mechanical properties of Ni-Ti alloys varies according to their chemical composition and manufacturing method, beneficial for handling these clinical situations. Despite having numerous instrument designs and metallurgy developing an appropriate technique is really important. Several instrumentation techniques have been adovocated in literatures for preparing curved canals. Among those various techniques; the zone technique, Reciprocating technique, Tactile controlled activation technique and Arithmetic crown down dynamic tactile instrumentation technique have shown more promising results without procedural errors. This poster depicts various specialized engine driven instrumentation considerations opted to deal with the challenging canals.

Occlusion – As viewed through the T-SCAN

N. Thejashree

D A Pandu Memorial R V Dental College, Bengaluru, Karnataka, India

OCCLUSION is defined as “Any contact between the incising or masticating surfaces of the maxillary and mandibular teeth” –GPT. Restorations are replacement of diseased or defective tooth structure in order to reestablish their appearance, function and integrity. Conventional way of assessing the occlusion post restorations is by using articulating paper. Though the restoration looks appropriate clinically; there are many chances of restoration being underfilled or overfilled leading to fracture, pain in the restored tooth, tooth fracture, tooth mobility, food lodgement eventually leading to failure. Hence, here we use T-scan for preoperative and postoperative occlusal analysis so as to further improvise on the restorative quality. T-Scan is a digital occlusion analysis system that records and measures tooth contact, force and timing in real-time using a thin, flexible, pressure-sensitive bite transducer embedded in a dental arch-shaped recording sensor. This is a comparative study, where-in a qualitative assessment of occlusion is carried out using two different restorative techniques - direct restorative technique and indirect restorative technique. Pre-treatment and post-treatment data are obtained and compared to derive the inference. Limitations of this technique include -cost and inability to measure absolute bite force value where only a qualitative analysis of improvements is realized using T-Scan. The sensors might get damaged when forces are concentrated over a small area, such as a sharp tooth cusp.

Nicolau syndrome: A downside of calcium hydroxide

Shalvi Purushottam Wadighare, Monika Vidhani

Rungta College of Dental Sciences and Research, Bhilai, Chhattisgarh, India

Calcium hydroxide has been used in endodontics since several years. Due to its antimicrobial properties, ability to dissolve tissues it is a choice of intracanal medicament. Although it has many benefits, there are some disadvantages too. One of the most common placement techniques for calcium hydroxide is delivery with needle and syringe. One such rare condition caused by pressurized application of calcium hydroxide in bleeding canal is Nicolau syndrome. Nicolau syndrome is a rare iatrogenic event of intramuscular or intraarterial injection of crystalloid suspension. Literature states that in endodontics it is caused by placement of non-setting calcium hydroxide via an injectable syringe into bleeding canals. Various cases of this syndrome showed signs and symptoms such as skin discoloration followed by severe pain and extensive inflammation leading to tissue necrosis. Various treatment modalities included were corticosteroids, anticoagulative regimen of heparin and antibiotic therapy. In the conclusion it can be stated that although calcium hydroxide is being used for years as intracanal medicament but its use to stanch bleeding is uncertain especially in case of pre- mixed injectable form.

National Dental College and Hospital, Mohali, Punjab, India

Introduction: In recent times, smile designing has gained popularity among adults, in which orthodontic alignment of teeth play a major role. However, the various orthodontic components like brackets and wires increase the predilection towards endodontic concerns. In certain cases, root canal therapy may be indicated, wherein determination of working length accurately prior to instrumentation plays a major role for favourable outcome. One of the methods of determining working length, Electronic Apex locators works on the principle of electrical conductivity. However, the effectiveness of apex locators is said to be hampered by presence of irrigants, saliva, intracanal medicaments and metal. Aim: To evaluate the effect of orthodontic brackets on the accuracy of electronic apex locators in determination of working length. Methodology: 20 freshly extracted mandibular incisors will be taken and access openings made, and actual working length determined using Ingle's method. Then, further divided into 2 groups of 10 each. One group will have orthodontic brackets placed on them and the other will be without brackets (Control). Each tooth will then be embedded individually into freshly mixed alginate mould, and the lip clip will be embedded into the alginate at: a) 1 cm, b) 1.5 cm, c) 2 cm, d) 2.5 cm and e) 3 cm from sample tooth. Then the electronic working length measurements will be taken and the data will be tabulated.

Greeta Sunny, Aishwarya Sanjay Awati

KLE VK Institute of Dental Sciences, Belagavi, Karnataka, India

Context: Endodontically treated teeth are more prone to fracture than vital teeth. Placement of barrier material in the canal orifice has been found to increase the fracture resistance of the teeth. Using materials with a modulus of elasticity and compressive strength close to dentin which can bond well to dentinal walls of root canal in the orifice, may provide good coronal seal along with stiffness and resistance against forces that generate root fractures. Few materials such as GIC, composites have been evaluated for their use as intraoffice barrier, but not many studies have reported the use of Biodentine and Cention-N as a barrier material. Aim: To evaluate and compare fracture resistance of endodontically treated teeth using Biodentine, Cention-N and Conventional glass ionomer cement (GIC) as intraorifice barriers using universal testing machine. Materials: Group 1- Biodentin; Group 2- Cention-N; Group 3- GIC. Methodology: 30 freshly extracted human Mandibular premolars were decoronated using diamond disk to obtain a standardised working length. Root canal was prepared using Protaper Universal, till F3. Obturation was done with F3 gutta percha using AH plus sealer. Samples were divided into 3 groups depending on intraorifice barrier used: Group 1- Biodentin; Group 2- Cention-N; Group 3- GIC. Coronal 3mm gutta percha was removed with heated hand plugger. Later the root canals were filled with different intraorifice barrier materials. All specimens were stored at 37 C and 100% humidity to allow the materials to set completely. Specimens were tested using Universal testing machine for evaluating the fracture resistance.

Intentional replantation – An innovative approach for management of separated endodontic instrument in the apical third of palatal root canal of a maxillary second molar using CBCT: A case report

Arindam Banik

Awadh Dental College and Hospital, Jamshedpur, Madhya Pradesh, India

Endodontic instrument separation is the most common cause leading to complications in endodontic therapy. The most common factors contributing to file separation are fatigue failure, torsional failure and corrosive failure. When a material is subjected to repeated stresses, it results in cyclic failure. Torsional failure occurs when an object is twisted and a portion of it gets locked and the remaining part continues to rotate till a point is reached where separation of instrument takes place. Corrosive failure is the result of combination of torsional and fatigue failure of an instrument presenting with signs of corrosion. Glossary of Endodontic terms defines intentional replantation as “insertion of a tooth into its alveolus after the tooth has been extracted for the purpose of performing treatment, such as root end fillings or perforation repair”. Bender and Rossman reported 81% success rate with the follow-up of 22 years. Intentional replantation is considered as a last resort where surgical endodontics or conventional root canal therapy cannot be performed. Factors determining success in intentional replantation are periodontal cell viability, removal of irritant, good apical seal and procedure carried out under aseptic condition with atraumatic extraction. This procedure is advantageous because it is a minimally invasive procedure and requires less operational time as compared to other treatment modalities. This case report describes a case of intentional replantation of a symptomatic maxillary second molar with non-retrievable separated instrument in the apical third of palatal root canal (extruded periapically) using CBCT imaging.

Aditee Agrawal

New Horizon Dental College and Research Institute, Bilaspur, Chhattisgarh, India

To devise a method to overcome the drawbacks of conventional matrix bands. Isomalt sugar (Anti-cariogenic) and Coconut oil were used to fabricate Isomatrix. Both ingredients offer high biocompatibility with nutritional benefits. Contact points and marginal adaptations of restorations remain appropriate. Achieving suitable interproximal contacts and contour is essential to avoid food impaction, periodontal disease, and recurrent decay. Isomatrix attains greater ease of handling and restoration than the typical matrix bands. It also requires lesser time for restoration than usual matrix bands. Furthermore, this material overcomes the trauma to the soft tissue as well as marginal breakage. Not to forget the ease of application and handling requiring no additional armamentarium and band replacement. The advanced matrix offers several advantages over the ordinary matrix band such as the absence of soft tissue trauma, lesser chances of marginal breakdown of the restoration, biocompatibility, and economical with proven feasibility of usage. It could be a worthy substitute for conventional matrix bands.

Prebiotic, probiotics and synbiotics

Nair Akshay Vasudevan

PMNM Dental College and Hospital, Bagalkot, Karnataka, India

Dental caries is a multifactorial disease that occurs because of the ecological imbalance between the inorganic components of the hard dental tissues and biofilms. The use of antibiotics seems to cause serious adverse effects, such as damage to the desired oral microbiome, pathogen resistance, and oral cavities more prone to dental caries, among other things. For this reason, a newly derived and preventively oriented method, probiotic therapy (i.e., the use of desired and harmless microorganisms) has been gaining ground for the past few years. Probiotics are defined as “live microorganisms, which when administered in adequate amounts, confer a health benefit on the host”. The term 'prebiotics', on the contrary, is used to describe “a selectively fermented ingredient that allows specific changes, both in the composition and/or activity in the resident microflora, that confers benefits upon host wellbeing and health”. The term 'synbiotic' is applied to products containing probiotics and prebiotics. In conclusion, the use of probiotics for use in oral care applications is gaining momentum. There is increasing evidence that the use of existing probiotic strains can deliver oral health benefits. In parallel, the potential of prebiotics to maintain and enhance the benefits provided by the resident oral microbiota will be investigated. However, whether considering probiotics or prebiotics, it will be essential to develop an understanding of the broad ecological changes induced in the mouth by their ingestion and the long-term consequences of their use on oral health and disease.

Biomimetic materials: Rebrith to enamel and dentin

Akshata V. Badiger

PMNM Dental College and Hospital, Bagalkot, Karnataka, India

Biomimetic materials are functional materials containing components having structural and technological similarities to natural (biogenic) prototypes. This concept also includes approaches and processes mimicking biological or natural ones reproduceing the physicochemical, mechanical, and biological properties at the nano- or macro scale. The integrity of collagen matrix structure is a prerequisite for effectively inducing biomimetic remineralization. Repeated low pH stimulation activates matrix metalloproteinase (MMPs) in dental caries. Activated MMPs cause the breakdown of collagen fibrils. Collagen stabilization is a major herdle to the clinical application of remineralization templates. Eexisting materials like bioactive glass, CPP-ACP, fluorides etc have been used to induce dentin remineralization lack the ability to stabilize dentinal collagen. Here, galardin-loaded poly(amido amine) (PAMAM)-NGV ([email protected], PNG) is constructed to induce collagen stabilization and dentin biomimetic remineralization simultaneously, in order to combat caries in dentin. PNG induces dentin remineralization in an environment with collagenase, meanwhile showing anti-caries efficacy in vivo. These findings indicate that PNG has great potential to combat dentin caries for future clinical application. A honokiol-loaded poly(amido amine) (PAMAM) dendrimer (PAMH) was constructed to combat early caries lesions in enamel. Honokiol released from PAMH was slower but more durable in a cariogenic pH environment than in a neutral pH environment. The findings indicated that PAMH had great potential to combat early caries lesions in enamel for future clinical application.

Dental materials when placed within oral cavity are fully contacted with saliva, gingival crevicular fluid and water. Most dental materials are in intimate contact with oral tissue for a long time; they must be noncytotoxic and biocompatible to have a harmonious interaction with host while performing desired functions. Nanotechnology is an art of manipulating matter on a scale of less than 100 nm to create numerous materials with various properties and functions. Graphene is a 2D single layer of sp2 hybridized carbon atoms with hexagonal packed configuration. Graphene family nanomaterials differ from each other in terms of surface properties, number of layers and size. Addition of graphene into dental cements leads to refinement of pore structure which not only strengthens the cement material but also blocks the entry for possible bacterial invasion. It could be promising reinforcing cementitious material for future dental application. The GFNs modified dental adhesive significantly inhibited the adhesion and growth of S. mutans without interfering its original mechanical performances and without producing a surplus of ROS. Graphene and its derivatives are versatile materials that present unique characteristics such as large surface area, high mechanical properties and can be transferred onto different substrates including polymers, biomolecules, DNA, and proteins. to enhance their properties. As they can be functionalized and combined with several biomolecules and biomaterials; Graphene family and materials, with superior and remarkable mechanical, chemical, and biological properties, are able to grab appreciable attention on the path of researches seeking new materials for future promising biomedical applications.

Bio markers in pulp

Divyanshu Choudhary, Shreya Agarwal

Darshan Dental College and Hospital, Udaipur, Rajasthan, India

The dental pulp can be affected by thermal, physical, chemical and bacterial phenomena which stimulate the inflammatory response as a way to eliminate pathogens and stimulate repair. The pulp tissue produces an immunological, cellular, and vascular reaction in an attempt to defend itself and resolve the affected tissue. Biomarkers are functional elements at the cellular or molecular level, playing important roles in health and disease. The dentin-pulp complex of the tooth houses several biomarkers at different stages of development, which play a very important role in the pathogenesis of dental caries, pulpal and periapical pathosis. Dental pain descriptions are subjective, clinical diagnosis alone is unreliable to accurately determine pulp inflammation severity and pulp tissue ability to respond to endodontic procedures. As a result, pulp vital therapy is usually performed following empirical decision-making criteria. Therefore, need for new pulp diagnostic tools are increasingly evident. Molecular-based strategies using the biomarkers are promising in determining appropriate clinical indications for vital pulp therapy and to optimize prognosis after pulp vitality therapy. By providing more precise diagnosis, molecular-based strategies will change the decision-making of dental practitioners and enhance patient assessment and treatment toward customized therapies. Decreasing root canal overtreatment provides both biological and socioeconomic advantages for patients. This poster presentation will highlight the various bio markers available in dentin pulp complex and their role in pathological conditions involving the dentin-pulp complex along with their role in modern day treatment planning.

Imaging always plays an essential part in diagnosing various orofacial diseases, especially various periapical lesions. Traditional radiographs help detect the lesion but cannot differentiate them. Also, it causes biological damage to patients due to ionizing radiation exposure. Recent decades have seen a revolutionary advent in Dental radiology in Computed Tomography (CT), Magnetic Resonance Imaging, Cone Beam Computed Tomography (CBCT), and Ultrasonography which are in the field of Diagnostic Endodontics. Ultrasonography (USG), also known as real-time echography or sonography, is an imaging technique where a beam of ultrasound propagates through the internal tissues and is reflected, absorbed or transmitted to form an image. Ultrasound is the sound energy with a frequency range above 20 kHz. The Ultrasonics (US) has emerged as a promising tool and gives the most reliable information. Today, almost all endodontic treatment and surgery can be done quickly with ultrasonic. It can estimate the content of periapical lesions, and vascularity helps differentiate lesions of endodontic origin. The Ultrasonics providing a better visualization with a conservative approach provides better results in access refinement, location of calcified canals, removal of separated instruments or posts. And with the use of the US, better action of irrigation solutions and condensation of gutta percha has also been noted. This poster aims at presenting various uses of ultrasound and its tips and gives importance to the broad applications in modern day endodontic practice.

One of the special materials used in endodontics, bioceramic materials help both the microbiological control phase (instruments, irrigation, intra-canal medication) and the filling phase (root and top filling) of root canal therapy go successfully. Bioceramics are biocompatible as well as bioactive materials. Alumina, zirconia, bioactive glass, coating and composite, hydroxyapatite, resorbable calcium phosphate, and radiotherapy glasses are examples of bioceramics, an inorganic, non-metallic, non-toxic, non-corrosive substance. Bioceramic materials interact well with organic tissue, form a chemical bond between dentin and filling materials, and form hydroxyapatite. They have antibacterial action, are hydrophilic in nature, and have outstanding sealing ability. They are also involved in tissue healing and pulp regeneration. The first bioceramic restorative dental cement was made of calcium phosphate. MTA was the first bioceramic material used in endodontics. Direct and indirect pulp capping and pulpectomy treatments, which are a part of endodontic therapy's purpose to maintain the vital pulp and promote a healthy periradicular periodontium, may require the use of bioceramic material. In dentistry, bioceramic materials have been employed for a variety of purposes, including root restoration, apical filling, perforation sealing, filling up bone defects, endodontic sealers, and regeneration aids. These varied characteristics make bioceramics one of the most appealing and distinctive materials utilised in endodontics.

A microinvasive approach: Resin infiltration


KD Dental College and Hospital, Kota, Uttar Pradesh, India

Resin infiltration is an advanced technology for arresting carious lesions, and for treatment of white enamel discoloration. This newer treatment modality lies between preventive and restorative therapies. Caries and white spot lesions causes alteration in chemical composition of the enamel mineral phase leading to formation of pores within the lesions. In this treatment, resin flows in the intercrystalline spaces of hypocalcified or demineralized enamel and stops the progression of caries and improves the refractive index of enamel as refractive index of this material is close to hydroxyapatite crystals. Advantages of resin infiltration are preservation of tooth structure, plugging of micropore forms in body of lesion, decreasing recurrent decay, absence of postoperative sensitivity and inflammation of pulp and also better esthetical outcome. It is available in two forms (i) ICON Resin Infiltrant Proximal- for incipient proximal dental lesions (ii) ICON Resin Infiltrant Smooth Surface- for removal of white spots and treating incipient caries on smooth surfaces of tooth. The proximal infiltration is a 4 step method consisting of separation, etching for 2 minutes followed by rinsing with water for 30 seconds, drying for 30 seconds followed by infiltration for 3 minutes. Smooth surface infiltration steps include etching for 2 minutes, visual examination in which preview of final result is shown, drying for 30 seconds and infiltration for 3 minutes. Hydrochloric acid, pyrogenic silicic acid, surface-active substances are present in etchant, 99% of the ethanol in the drying syringe, Methacrylate-based resin matrix, initiators, and additives are found in infiltrant.

Endodontic microsurgery: The betterment of traditional endodontic treatment

Prinaxy Byxyx

KD Dental College and Hospital, Kota, Uttar Pradesh, India

Endodontic microsurgery is an indispensable part of standard endodontic treatment and is undergoing major advances. Improved visibility and illumination because of operating microscope, advances in the ultrasonic instrument technology and developments in root- end filling materials have brought in technical advances which lead to higher success rates in endodontic microsurgery compared to traditional surgery. When we compare it with traditional root end surgery, there are key differences in their respective flap designs, access armamentarium, size of osteotomy, instruments used and root- end materials. Apart from the traditional Mineral Trioxide Aggregate (MTA) as a post surgery obturating material for the apical end of the root, other tricalcium silicate based biomaterials have been introduced as potential root- end filling materials because of their ability to release Calcium hydroxide in solution. These new biomaterials have better physical properties when compared to traditional MTA like exceptional dimensional stability, high mechanical bond strength, high pH, radio opacity and hydrophilic setting properties. The approach has introduced the usage of 3 D printed templates which has in return increased the accuracy and viability of guided endodontic microsurgery in predefined guided osteotomies and root resections. By using state-of-the-art equipments, instruments and materials, it can be believed that microsurgical approaches produce predictable outcomes in the healing of lesions of endodontic origin. With a high percentage of successful treatment outcomes of conventional endodontics together with high success of surgical endodontics almost all teeth with endodontic lesions can be successfully treated.

Transforming endodontics: “Simplifying the complex with 3D printing”

Arjeet Ghosh

KD Dental College and Hospital, Kota, Uttar Pradesh, India

The newly developed 3D printing in dentistry adds a fresh perspective to the formulation and delivery of treatments. The process of additive manufacturing, in which layers of material are added to construct the three-dimensional model is used in computer-aided design, is precisely the inverse of subtractive manufacturing techniques. A 3D printed model has the advantage that a range of materials can be selected depending on the application. CBCT data can be used in 3D printing to create a guide that can accurately locate calcified canals. Using guided endodontic access lessens the risk of perforations when calcified canals are attempted to be located and navigated. In osteotomy right angulation and depth of preparation are challenging where 3D printed stents can reduce the risk through avoiding damage to the neurovascular structures and adjacent teeth. In traditional auto-transplantation, the recipient location is prepared using a tooth as a guide and frequent fitting attempts, increases the risk of injuring the PDL and lengthening the appointment, both of which have a significant negative impact on prognosis. Replicas can be printed using computer-assisted rapid prototyping which lessens the potential for PDL damage and extraoral time. For preclinical, extracted teeth, and resin teeth which serves as the major tools used in dental education, 3D reconstruction of complex cases is achievable with the aid of CBCT data. The poster illustrates how 3D printing has evolved in endodontics and stand out as a novel concept in the field of dentistry.

Matrix metalloproteinases in dental caries

Nima Wangziom Mosobi

KD Dental College and Hospital, Kota, Uttar Pradesh, India

MMPs are a family of structurally and functionally related endoproteins, collectively capable of degrading most components of the extracellular matrix. According to some theories, MMPs are crucial in the demineralization of the dentin organic matrix by bacterial acids and, consequently, in the prevention or advancement of caries. Both saliva and dentin can be the source of host-derived MMPs, which may be triggered by an acidic pH caused by lactate released by cariogenic bacteria. Once active, they can digest demineralized dentin matrix once salivary buffers have neutralized the pH. The possible sources of MMPs in the carious lesion are – saliva, gingival crevicular fluid and MMPs produced by the odontoblast. During the caries process, the mineral portion of the dentin dissolves, exposing the organic matrix to degradation by host-derived and bacterial-derived enzymes such as MMPs present in the dentin. MMPs present in dentin are produced by odontoblasts during dentin matrix secretion. When mineralization of the collagen matrix occurs, MMPs remain trapped in the mineralized matrix in an inactive form and can be re-exposed and activated during caries development. The salivary MMPs frequently contribute significantly to the deterioration of the dentine matrix. Additionally, caries has a tendency to boost endogenous MMP-2 production. An acidic pH during the carious process may cause the odontoblasts to produce MMP as well as to become activated, which would increase MMP's ability to break down proteins and accelerate the breakdown of dentine matrix.

Nanopropellers: The future of the canal disinfection

Aditya Kumar

KD Dental College and Hospital, Kota, Uttar Pradesh, India

Failure of root canal treatments occur worldwide due to remnant bacteria (common species: Enterococcus faecalis) deep in the dentinal tubules located within the dentine tissue of human teeth. The complex and narrow geometry of the tubules renders current techniques relying on passive diffusion of antibacterial agents ineffective. The potential of actively maneuvered nanobots (nanopropellers) to disinfect dentinal tubules, which can be incorporated during a standard root canal procedure. The magnetically driven nanobots (nanopropellers) can reach the depths of the tubules which is not possible with current clinical practices. Subtle alterations of the magnetic drive allowed both deep implantations of the nanobots isotopically distributed throughout the dentine and spatially controlled recovery from selected regions. The integration of bactericidal therapeutic modality with the nanobots, thereby validating the tremendous potential of nanobots in dentistry and nanomedicine in general.

Tissue engineering scaffolds for dentine pulp complex regeneration

Vaishali Moryani

Mahatma Gandhi Dental College and Hospital, Jaipur, Rajasthan, India

Clinical interventions for carious lesions range from minimally invasive coronal restorations to root canal therapy. Pulp capping has the traditional approach for maintaining pulp vitality in deep carious lesions, but irreversible pulpitis and reinfection are common sequalae for this treatment. When affected pulp involvement is beyond repair, the dentist has to perform endodontic therapy. On-going research strategies have failed to overcome the limitations of existing pulp capping materials so that healthy and progressive regeneration of the injured tissues is attained. Preserving pulp vitality is crucial for tooth homeostasis and durability, and thus, there is a critical need for clinical interventions that enable regeneration of the dentin-pulp complex. The identification and development of appropriate biomaterials for dentin-pulp scaffolds are necessary to optimize clinical approaches to regenerate these hybrid dental tissues. Likewise, a deep understanding of the interactions between the micro-environment, growth factors, and progenitor cells will provide design basis for the most fitting scaffolds for this purpose. First introduce the long-lasting clinical dental problem of rescuing diseased tooth vitality, then limitations of current clinical therapies and interventions to restore the damaged tissues, and the need for new strategies to fully revitalize the tooth. Then, comprehensively report on the characteristics of the main materials of naturally-derived and synthetically-engineered polymers, ceramics, and composite scaffolds as well as their use in dentin-pulp complex regeneration strategies. Finally, present a series of innovative smart polymeric biomaterials with potential to overcome dentin-pulp complex regeneration challenges.

Cold plasma – The new cosmos in pain free and fear free dentistry

Naveen Chaudhary

Jaipur Dental College, Jaipur, Rajasthan, India

Plasma is defined as a gas in which part of the particles is present in ionized form. Thus, plasma consists of positively and negatively charged ions as well as radicals, neutral and excited atoms and molecules. Dental applications of plasma have emerged because of a new version of plasma technology, the so-called “non-thermal atmospheric” or low-temperature plasma or cold plasma which is characterised by a low ionization at atmospheric pressure. Cold plasma is highly efficient at killing bacteria in an inexpensive manner. Sterilization of metal, rubber and plastics by plasma has a promising sterilizing effect. It is effective in killing both E. coli and bacillus. A plasma needle can be used to sterilize dental cavities or root canals which is more effective than lasers or chemical and mechanical sterilization. In root canals, it efficiently killed E. faecalis without causing any painful sensation. Even in biofilms where these bacteria cannot be eliminated effectively by calcium hydroxide interappointment medication. It also increases the bond strength at the dentine/composite interface which improves composite performance, durability and longevity. Besides, it enhances the bleaching effect of the hydrogen peroxide and also increases the tensile and shear strength between post and composite. This technology enables the dentist to perform procedures without shots and pain. It operates at room temperature and does not cause bulk destruction of the tissue being superior to lasers. So, this is a valuable tool in dentistry for painless and fear-free dental treatment.

Guided endodontics: A guide to vanquish the obliteration

Vishnu Chernad

MES Dental College, Perintalmanna, Kerala, India

Primary objective of an endodontic treatment is complete disinfection of the root canal system. It is hard to achieve when the pulp chamber is obliterated. Such cases pose a challenge to the endodontist in achieving the canal access with minimal removal of the pericervical dentin. It has high risk of perforating the pulp chamber floor or walls in the attempt to find the canals. In such scenarios guided endodontics comes in handy for an endodontist which helps him find and negotiate the canals in a much lesser time. It requires CBCT and intra oral scanned data respectively in the DICOM (Digital Imaging and Communication in Medicine) and STL (Standard Triangle Language) formats. Dental lab prepares a template by using virtual sleeve and a drill path based on the provided data. Using this template the access can be prepared using a specific bur which would eventually lead to the orifices of the canals. This technique can be adopted in anteriors as well as posteriors. Its convenient usage in case of limited mouth opening and the advantage of preserving maximum amount of tooth structure as possible makes this technique a potential focus in the future endodontics.

Harshad Ramchandra Alat

Saraswati Danwantri Dental College and Hospital, Parbhani, Maharashtra, India

Root canal irrigation is considered an important procedure of root canal treatment as it involves the healing of periapical tissues after treatment. In root canal irrigation, the motto is prevention of reinfection. Standard irrigation techniques are using common irrigants like NaOCl, chlorhexidine, EDTA etc but in this study, advanced root canal irrigants are reviewed. The newer irrigants like tetraclean, MTAD, ECA ( Electronically activated solutions), ozonated water, herbal induced irrigants can all serve as an adjunct to the commonly used root canal irrigants. Potential newer/advanced irrigants serve as a substitute for traditional endodontic irrigants. With the recent studies performed and available literature, even though none of the irrigants fully satisfy the requirements of an ideal root canal treatment they can all be used as an adjunct over the commonly used irrigants.

Merging the gap – Management of horizontal root fracture in the middle third: A report of two cases

Parvathi Sudeep

JSS Dental College and Hospital, Mysore, Karnataka, India

Horizontal root fractures are quite uncommon as a result of dental trauma, which is one among the causes for permanent teeth loss. Most of these injuries occur within the middle third of the root, while a few of them result in cervical or apical third fractures. The prognosis and treatment plan in these cases depend on the reporting time, the age of the patient, the level of the fracture, and the gap between the segments. The method of treatment includes repositioning and immobilization of the fractured segments. This case report features two clinical cases of horizontal root fracture in the middle third of maxillary anterior teeth due to dental trauma. Following root canal disinfection and apical segment obturation, the fractured segments were re-approximated with the help of an intra - radicular splint (post/file). Flap surgery was done in one case to remove the granulation tissue to aid in the placement of a bioactive material (Biodentine). On one year follow up, the patients were clinically asymptomatic and radiographic evidence of healing was noted. Management of horizontal root fractures pose a challenge, as the treatment can be either simple or complicated. Teeth with poor prognosis are usually advocated for extraction and advised for the placement of implants, but in the present cases, the patients were keen on saving their natural teeth. Interdisciplinary approach along with the use of technologies like CBCT for diagnosis and bioactive materials like Biodentine add to the success of treatment. However, long term follow up is required.

“Seal and heal” - Management of horizontal middle third root fracture after previous root canal therapy using MTA – A case report

Ankita Singh

JSS Dental College and Hospital, Mysuru, Karnataka, India

Andreasen states that the root fractures in permanent teeth are relatively infrequent occurrences, implicating in 0.5-7% of all dental traumas. Horizontal root fractures occur mainly in the anterior region of the maxilla, usually owing to a frontal impact, more frequently observed in fully erupted teeth with complete root formation. Horizontal fractures occur most frequently in the middle third of the root and rarely in the apical-third. Management of horizontal root fractures presents a formidable challenge for clinicians because of the difficulty of achieving a stable reunion of fracture fragments. Mineral trioxide aggregate (MTA) is a biocompatible material with numerous interesting clinical applications in endodontic. The material appears to be an improvement over other materials for some endodontic procedures that involve root repair and bone healing. Current literature supports its efficacy in promoting the overgrowth of cementum and it may facilitate the regeneration of the periodontal ligament because of its alkaline pH of 12.5 and the presence of several mineral oxides in its composition. This case report presents the novel approach toward approximation, stabilization, and endodontic management of a horizontally fractured central incisor using splinting technique, and MTA. Short-term follow-up of the case showed promising results both clinically and radiographically.

Seal and heal

Patel Kruti Bhailalbhai, Anjali Subramanya

Ahmedabad Dental College and Hospital, Ahmedabad, Gujarat, India

Dental composites are most commonly used restorative material of choice since last few decades as they have the ability to bond to the tooth structure, have acceptable aesthetics, have satisfactory mechanical properties and ease of use. However, Composites have few downsides like: secondary caries and bulk fracture. Composite restorations often fail due to the accumulation of micro-cracks resulting from factors such as masticatory forces and thermal stresses. Hence the need to inhibit fracture and crack propagation in resin-based restorations is considered fundamental. One way to improve longevity is to repair micro-cracks. Toward this end, a new type of Self- healing dental composites (SHDC) have been introduced, made with contemporary dental components plus two additional ingredients: a healing powder (HP, strongtium fluoroaluminosilicate particles) and a healing liquid (HL, aqueous solutions of polyacrylic acids) that is enclosed within silica microcapsules As micro-cracks develop, they will break the microcapsules in their propagation path, thereby releasing HL. This liquid will then react with particles of HP exposed by the crack formation, forming an insoluble reaction product that fills and seals the cracks. Self-healing resin composites are promising materials that help to produce a stable interface, resisting secondary caries and reducing marginal gaps. Thus, self-healing composites have shown significant enhancement in extending the service life of resin composites.

Oral health is important because it can deeply affect human health and quality of life. The main common oral diseases include dental caries, periodontal diseases, tooth loss, and oral cancer. Bone defects caused by traumas, infections, or tumours are one of the most common diseases in dental field. Currently, many efforts have been taken to repair tissue defects. Tissue engineering is commonly considered as a superior treatment strategy, where scaffolds played a vital role. Nanomaterials have shown wonderful performance in improving the strength, resistance towards wear of tooth fillers and sealants and excellent antimicrobial properties in the application of restorative materials. Among various nanomaterials, graphene, is a promising two-dimensional (2D) carbon-based nanomaterial, also it is the thinnest and strongest material. Owing to perfect physical properties, electrical conductivity, and excellent biocompatibility, graphene and its derivative have attracted much attention in the field of dentistry and tissue engineering, resin additives, antibacterial application, adhesive, cements and silane primers, tooth whitening and pulp tissue regeneration. Graphene nanoplatelets (GNP), a non-toxic hydrophobic nanomaterial with antimicrobial and anti-biofilm properties are also used as filler of dental adhesives. Recently, nanographene oxide (NGO), an oxidized derivative of graphene, has earned popularity due to its high surface area, high functional groups and cost-effective large-scale synthesis. They are also used in combinations to improve anti–microbial effects against E. faecalis after photodynamic therapy. This poster presentation will highlight various uses of graphene-based nano-materials in Conservative Dentistry and Endodontics.

Nanotechnology is the study of analysing and creating materials at nano dimensions by relocating atoms to create materials with superior qualities. Currently, newer technologies are being tested in Endodontics, mainly towards overcoming the microbial challenge. A few examples of natural biomaterials include collagen fibrin, natural silk, and chitosan. When compared with bulk materials, the nanoparticles provide greater benefits as they are relatively low stability molecules having low coordination and unsatisfied bonds that allow them to interact with other particles effectively and with ease. Chitosan is a natural biopolymer that is purified mainly from chitin. It has anti-microbial, anti-oxidant, and anti-tumor effects. Bone formation is accelerated by chitosan through increasing osteoblasts formation in bone tissue, and it has also the capability of connective tissue regeneration. Chitosan-based nanoparticles can eliminate bacterial biofilm, inactivate endotoxins, improve resistance to biological degradation (resorption), and promote bone regeneration. The aim of my poster is to elaborate the application of chitosan nanoparticles in the field of Endodontics.

Every tooth has its own anatomic contour and specific relationship with adjacent supporting structure, and opposing tooth. Primary objective of restorative procedure is to establish a proper interproximal contacts and contours. The failure to attain these relationships will cause premature failure of restorations, periodontal problems as well as carious involvement of another tooth. Traditionally used matrix systems like ivory systems and Tofflemire are cumbersome to use, time consuming and also cause discomfort to the patient. So, to overcome this factor, various manufacturers have come forward to improve the design, precision of the matrices which are easy, quick, great at confirming the tooth, easy to burnish and to provide better adaptability and comfort to the patient. Bioclear Matrix System was introduced by Dr. David Clarke, has gained its traction in the recent times as it allows for a modern approach to composite dentistry.

“Hemisection”: A hope for saving tooth from abyss of despair

Ayushi Khanna, Charoo Lata

Rama Dental College, Kanpur, Uttar Pradesh, India

In multirooted teeth we do encounter cases with a guarded prognosis and saving the tooth becomes a challenge, as the pathology seldom display in isolation, hence requiring a multidisciplinary approach. One such treatment modality is “HEMISECTION” wherein molars with bifurcation/trifurcation involvements are treated. Hemisection is removal of compromised root and crown part of tooth and retain the unaffected tooth structure, surrounding alveolar bone and periodontal tissue that, otherwise, would have been lost. It is an optable solution for caries, resorption, perforation, fused teeth or periodontal damages that can no longer be restored non-surgically. Thus, these case reports describe hemisection as a successful method to preserve healthy portion of grossly carious tooth structure of molar with periodontal and periapical involvement. Hemisection followed by prosthetic rehabilitation of rightly done case selections yielded satisfactory result. With careful treatment planning and precise surgical management, undesirable consequences of tooth loss were prevented.

Artificial intelligence (AI) has the potential to replicate human intelligence to perform prediction and complex decision making in health care and has significantly increased its presence and relevance in various tasks and applications in dentistry, especially endodontics. AI models (eg, convolutional neural networks and/or artificial neural networks) have demonstrated various applications in endodontics such as studying root canal system anatomy, detecting periapical lesions, root fractures, determining working length measurements, predicting the viability of dental pulp stem cells, and predicting the success of retreatment procedures. AI demonstrated accuracy and precision in terms of detection, determination, and disease prediction in endodontics. AI can contribute to the improvement of diagnosis and treatment that can lead to an increase in the success of endodontic treatment outcomes. The future of this technology was discussed in light of helping with scheduling, treating patients, drug interactions, diagnosis with prognostic values, and robotic-assisted endodontic surgery. However, it is still necessary to further verify the reliability, applicability, and cost-effectiveness of AI models before transferring these models into day-to-day clinical practice.

Digital smile design

Debajit Sarkar

Rama Dental College, Kanpur, Uttar Pradesh, India

A fundamental objective of an aesthetic treatment is the patient's satisfaction and that the outcome of the treatment should meet the patient's expectation of enhancing his/her facial aesthetics and smile. A patient constantly doubting the end result of the treatment, which is an irreversible procedure, can be motivated and educated through Digital Smile Designing (DSD) technique. DSD is a technical tool which is used to design and modify the smile of patients digitally and help them to visualize it beforehand by creating and presenting a digital mockup of their new smile design before the treatment physically starts. It helps in visual communication and involvement of the patients in their own smile design process, thus ensuring predictable treatment outcome and increasing case acceptance. This poster reviews the aspects of digital smile designing in aesthetic dental practice pertaining to its use, advantages, limitations and future prospects.

Incorporating plasma physics with dentistry – Applications of nonthermal atmospheric plasma

Dhruvee Sharma

Daswani Dental College and Research Center, Kota, Rajasthan, India

The recent enormous progress in understanding of plasma physics and development of plasma jet has attached Focus on the application of plasma in medicine and dentistry. Plasma is an electrically conducting medium that responds to electric and magnetic field. Cold Atmospheric Plasma (CAP) is known to be nonthermal as it has electron at a hotter temperature than the heavy particles that are at room temperature. Cold Atmospheric Plasma is a specific type of plasma i.e., <40° C at the point of application. Due to the presence of reactive species at low temperature the biological effect of non-thermal plasma has been studied for application in the medical area. It could become a new and painless method to prepare cavities for restoration with improved longevity. Also it is capable of bacterial inactivation and noninflammatory tissue alteration, which makes it an attractive tool for the treatment of dental caries and for composite restorations. Plasma can also be used for tooth whitening. Plasma is beneficial for improving the quality of restoration and reducing the microbial load.

Ahmedabad Dental College and Hospital, Ahmedabad, Gujarat, India

Octenidine dihydrochloride is a type of bispyridine antimicrobial compound that carries 2 cationic active centers per molecule and has shown antimicrobial effects which are broad spectrum in nature and includes both gram-positive and gram-negative bacteria, fungi, and several viral species. It exerts bactericidal/fungicidal effects by interfering with cell walls and membranes. It is widely utilized in the medical field for skin burns and decontaminating mucous membranes and open wounds. It is also utilized in mouthwash formulations and other dental applications. Octenidine dihydrochloride used in the form of mouthrinse can be beneficial to inhibit bacterial plaque accumulation and progression of dental caries in humans. Octenidine dihydrochloride has shown relative non-cytotoxicity at the site of action and good antimicrobial activity. Octenidine Dihydrochloride is a recently investigated solution and few studies have recommended it to be used as an alternative irrigant against E. faecalis infection. Octenidine has also been tested against E. faecalis. It has demonstrated promising results in disinfecting root canal dentine after different exposure times.

EAER: Healing without drilling

Rimpy Mehra

Government Dental College, Shimla, Himachal Pradesh, India

Dental caries is one of the most common dental issues among the population irrespective of age, gender and region. Recently there is a shift from the restorative model to a more minimally interventive and patient centered approach to reduce anxiety and fear of the patient. EAER (electrically accelerated and enhanced remineralization) is a novel new clinical method of caries remineralization being developed to address the unmet clinical need identified by modern caries management strategies to keep whole enamel through remineralization of clinical caries as a form of nonoperative caries treatment for initial stage and moderate lesion. EAER attempts to restore caries lesions equivalent to healthy enamel, it works by using iontophoresis to apply a small electric field from a custom made device to drive mineral molecules from a reservoir into deepest parts of caries lesion, which have been cleaned and conditioned. This creates an environment with a surfeit of suitable minerals collecting within the subsurface lesion, that encourages remineralization to occur and that matures to give desirable hardness and mineral density. The remineralising agent that is applied to the lesion can be in the form of pastes or more fluid liquid formulations in such a way as to create a reservoir of mineral material near to or on the lesion surface. It can remineralize clinically significant caries throughout the depth of the lesion and enamel formed is harder than the healthy enamel. But there is limited evidence of success in cases of pulpal involvement.

Matrix transfer; an integral of aesthetics

Desai Prathmesh Prakash

Government Dental College, Shimla, Himachal Pradesh, India

In aesthetic dentistry direct composite bonding procedures are considered to be most conservative and minimal invasive restorative techniques for management of worn dentition and aesthetic shape forms. In anterior composite restorations to provide better aesthetics these restorations can be done employing either multilayering different shades technique or single shade technique using matrix or base. The Poster intends to present different methods of direct composite restorations using Matrix transfer techniques which are used to directly convey planned information from diagnostic wax-up to a definitive direct composite restoration. These transfer techniques have been developed to provide better control over free hand approach in maintaining anatomy as well as thickness and position of teeth. The Poster highlights advantages and disadvantages relevant to these techniques. This poster focuses on restoration of single tooth for Class ?V restoration or simultaneous restoration of multiple teeth such as during diastema closure and closure of spacing between teeth, using different impression materials in the form of part of planned partial contour or full contour matrix transfer techniques based on accessibility to cure composite.

Mystery of a butterfly tooth

Suhani Pandya, Khatri Ashi Ravindra

Karnavati School of Dentistry, Gandhinagar, Gujarat, India

The ''Butterfly'' effect is an optical phenomenon, photographed by Beust in 1931, which is observed in transverse sections of some tooth roots. It has been attributed to dentinal tubular sclerosis which differs in buccolingual and mesiodistal directions, and this difference creates a characteristic butterfly shaped appearance as sclerosed dentin appears more translucent than normal dentin. In a study by Assil A. Russell the density of dentinal tubules was significantly higher in some of the root sections when cut mesiodistally and lowest in them when cut buccolingually regardless of the age group and this trend was consistent across all age groups. The difference in the density of tubules between the mesiodistal and buccolingual aspect are seen throughout the entire length of the root. The effect may have significant clinical implications like the teeth with the butterfly effect may be weaker and are thus more prone to vertical root fracture in the buccolingual direction. Butterfly effect also affects the sealing ability of the resin-based sealers which binds to the dentin by forming resin tags in to the dentinal tubules. It can also affect the retention of fiber-reinforced composite post within root canals and its adaptation to the post space, type of endodontic cement, adhesive and cementation system, and operative procedures. Calcium hydroxide and antibiotic pastes should be used with caution in endodontic treatment in teeth exhibiting butterfly effect as it decreases the dentin microhardness values after treatment.

Curbing the unwanted menace: A case series of role of CBCT in managing resorptive defects

Aneetinder Kaur

BJS Dental College, Ludhiyana, Punjab, India

With the recent advancement in diagnostic and treatment modalities in Endodontics, the outcomes and success of Endodontic treatment have become more predictable. Endodontics aims to retain the tooth in a functional form for as long as possible. Root resorption refers to noninfectious damage related to the loss of hard and soft dental tissue that results from clastic cell activity. These defects are particularly tricky to manage and require a proper diagnosis, constant monitoring along with a vigilant approach to managing them. In the past teeth with resorptive defects were usually deemed hopeless but recent developments particularly the use of Cone beam computer tomography in Endodontics has particularly aided in the diagnosis and management of such resorptive defects. This poster aims to bring light to the management of two different types of Resorptive defects and the Successful role of CBCT in the diagnosis and management of such Resorptive Defects.

Creating vibrant smiles with esthetic implants

Siddharth Baror

Sharad Pawar Dental College and Hospital, Wardha, Maharashtra, India

In the early years of modern implantology, the chief concern was tissue health and implant survival. Over the last decade, there has been an increasing appreciation that aesthetics is just as important to the success of the final restoration as health. Indeed, it can be said to represent a different aspect of health. In the anterior maxillary zone, the aesthetic achievement of implant therapy is as important as the implant survival rates. Several factors contribute to this success and can be objectively evaluated. These include the patient's healing capabilities, the level and condition of the existence of hard tissues, and the provisional and final restorations. In addition to these objective factors, implant positioning also plays a significant role in achieving this “Success”. Placement of a dental implant in the aesthetic zone is a technique-sensitive procedure with little room for error. A subtle mistake in the positioning of the implant or the mishandling of soft or hard tissue can lead to aesthetic failure and patient dissatisfaction. With this poster presentation, I would like to conclude that an understanding of bone and soft tissue dimensions have also been essential to overall implant success in the aesthetic zone and as further research is concluded they will continue to have an even greater impact on improving overall aesthetic and functional implant success in the anterior maxilla.

A novel biocompatible sealer: PES

Prabhat Ravindra Pande

Dr. Hedgewar Smruti Rugna Seva Mandal Dental College and Hospital, Hingoli, Maharashtra, India

Endodontic sealers play a vital role in the obturation of root canal space. The objective of obturation is to seal the coronal and apical pathways of leakage and to entomb any remaining bacteria in the root canal system during an endodontic treatment. Gutta-percha (GP) combined with a sealer is the most commonly used material for this purpose. However, this approach may not provide a complete bacteria-tight seal of the canal. The sealer's ability to penetrate dentinal tubules consistently and effectively is a crucial factor influencing the choice of material for root canal filling, which is affected by film thickness, viscosity, and expandability of the sealer. PES (polyurethane expandable root canal sealer) is a new material and my poster aims to provide you a brief idea about this sealer. It can provide better penetration into dentinal tubules, cul-de-sacs, and anastomoses, which may enhance the sealing ability of obturation materials and result in less unfilled areas in the root canal space and increase the success rate of root canal treatment.

Hybrid ceramics – A compound restorative solution

Trupti Anant Shirgapur

Bapuji Dental College and Hospital, Davangere, Karnataka, India

CAD-CAM restorations are a major technological development that has focused to address the aesthetic needs and optimum compatibility to the human dentition. Hybrid dental ceramics is an emerging concept in the field of material science. The ceramic and resin components are consistent in various brands that are available commercially, however they significantly vary in their microstructure and degree of filler. Hybrid dental ceramics are broadly categorised as polymer-infiltrated ceramic network (PICN) and resins with dispersed fillers. In order to simulate the specific structure and composition of the spongy bone and dentin which consists of relatively weak and brittle inorganic constituents and organic matrix that provides elasticity, a novel kind of interpenetrating phase material has been developed referred as 'Polymer Infiltrated Ceramic Network' (PICN). VITA Enamic is an example of a PICN. Several materials, including Lava Ultimate, CAMouflage NOW, CERESMART etc are in category of resins with dispersed fillers. All hybrids have a modulus of elasticity similar to dentin, and modulus of resilience significantly higher than feldspar-based and glass-ceramics, thus significantly higher stress can be absorbed without permanent deformation or failure. These superior mechanical properties make them the material of choice for the clinical situations with limited interocclusal space, crowns over implants, where the periodontal ligament is already lost. They also show easy repairability, limited tooth preparation and virtually no chipping. This poster aims to highlight the applications of hybrid ceramics in clinical situations challenging the use of other conventional materials.

Polyurethane expandable root canal sealer – An innovative material

Jetti Manogna

Bapuji Dental College and Hospital, Davangere, Karnataka, India

The long-term success of root canal therapy (RCT) majorly depends on the complete debridement, disinfection and obturation of the root canal system (RCS). In RCT, the purpose of obturation is to provide a 3D filling for the RCS and to prevent any leakage pathways either from coronal or apical directions. The goal of obturation is to entomb any remaining bacteria in the root canal system during an endodontic treatment. This goal of obturation cannot be achieved without endodontic sealers, which are usually combined with gutta-percha to provide complete filling of root canal space. Considering the intricacies of the RCS, expandable sealer was introduced to the field of endodontics. Polyurethane Expandable Sealer (PES) is a novel endodontic sealer with expansion ability and has recently been patented. It has expansion ability based on foam formation. According to previous studies, the biocompatibility and penetration ability of PES were evaluated and the results of an MTT assay and choroidal neovascularization assay (CNV) showed that PES was biocompatible and was able to penetrate the dentinal tubules. This poster aims to highlight the application of Polyurethane expandable root canal sealer and emphasize its benefits in endodontics.

Nanobubbles: The game changer

Shwetika Vipul Patel, Viraj Narendra Talsania

AMC Dental College, Ahmedabad, Gujarat, India

The current irrigation protocols used in endodontic disinfection are limited in penetration and disinfection of the dentinal tubules. Nanobubble (NB) water technology is used in endodontics for disinfection, especially in the context of enhancing the penetration and disinfection efficiency of intracanal medicaments and irrigants used in regenerative endodontic treatment. NB was found to be more effective than 17% EDTA without affecting the microhardness levels. NB water is produced by the discharging of pressurized gas into water in a predetermined amount through nano porous polypropylene ?lm. This results in stable bubbles with a size ranging between 120 and180 nm containing a high pressure, 0.1–0.2 MPa. NBs containing pressurized air could cause pressure waves to remove ?ne particles on the surface of solid materials. Furthermore, NBs can increase the wettability and decrease the surface tension of the liquid. These properties may explain the improved disinfection properties and the complete removal of the smear layer without demineralization or damage to the tooth structure. NBs alone could not have a direct effect on killing bacteria. The effect of NBs is dependent on removal of smear layer by irrigation and enhanced delivery of medicament into dentinal tubules. NB appears to be a promising irrigant to further enhance root canal disinfection. NB water has the potential to enhance the delivery of medications to dentinal tubules. NB water may be a promising adjunct to endodontic irrigants and medicaments.

Dynamic navigation: A real time guide

Satabdi Chakravarty

Vydehi Institute of Dental Sciences, Bengaluru, Karnataka, India

In order to minimize the risk of technical errors and to reduce the treatment time, a computer-assisted therapy approach was developed to localize calcified root canals in a minimally invasive way, and the term 'Guided Endodontics' was coined. This approach in endodontics is going to change the future of dental practice with Minimal Invasive Endodontics (MIE) that includes preservation of structural integrity of tooth, conservative access cavity designs, guided endodontic access, 3D imaging, loupes and dental operating microscope. Recently, in the field of endodontics, guided endodontics was introduced that utilizes these computer-aided 3D systems used for surgical and non-surgical endodontic procedures. 3D guided endodontics can be achieved in two ways- Static and Dynamic navigation. Static guidance uses a fixed surgical template based on a preoperative CBCT which is produced with CAD- CAM. A disadvantage of the static surgical guides is that the expected angulation, size, depth cannot be altered during the treatment therefore, in 2000, dynamic navigation was implemented to overcome this limitations by providing the operator with a real-time navigation tool. Dynamic guidance can visualize the bur on screen in 3D and control the removal tooth of structure. It uses information from patients CBCT to plan access cavity, overhead tracking cameras relate the position of bur in 3D by looking at the software interface, DGE is safer than traditional freehand technique as it overcomes procedural errors and preserves structural integrity of tooth even in most challenging cases and is soon going to be the future of Endodontics.

Nanobots – Travelling from Sci-fi to denti!

Ayushi Tibrewal

Government Dental College and Hospital, Mumbai, Maharashtra, India

With the emerging advancements in the field of Endodontics, the quest of delivering root canal treatment with long term success is intensifying. The failure rate for root canal treatment worldwide attributes to the inadequate disinfection of the canals. Conventional methods and the current techniques of disinfection render some bacterial remnants in the dentinal tubules and reach upto a limited depth only. Thus the researchers have introduced the Nanobots or Nano-Robots that use specific motility mechanisms to penetrate upto thousands of depth into the miraculous anatomy of the dentinal tubules. These nanobots are already being used in the medical science for drug delivery, but their use in dentistry has not been established yet. These are the magnetically driven devices that travel under the effect of a magnetic field and can be retrieved by controlling and modifying the orientation of this magnetic field. It utilizes a hyperthermia-based bactericidal method, where the magnetic layer embedded in the nanobots can be converted to a localized heat source. This is a physical method of treating bacterial infection where the possibility of causing antimicrobial resistance is nil. However, the heat generated by the nanobots is localized to a few micrometers. Researchers do foresee the possibility of applying multimodal bactericidal strategies, where the nanobots may be engineered for controlled drug release as an addition to the physical method. The purpose of this poster is to make good use of the nanotechnology as a bactericidal therapeutic modality in dentistry for better disinfection.

A recent discovery of revolutionary clustered regularly interspaced palindromic repeats (CRISPR) is a gene editing tool that provides a type of adaptive immunity in prokaryotic organisms, which is currently used as a revolutionizing tool in bio medical research. Even though this technology has enormous biomedical applications in various sectors, this poster will be emphasizing on both the therapeutic and diagnostic mechanisms developed in the field of dentistry which could be promising in the field of clinical dentistry. Clustered regularly interspaced short palindromic repeats-Cas9 technology found in bacteria and archaea is a RNA guided genome editing tool, has its dawning from immune defense mechanism, which provides immunity to the host against invading nucleic acids such as viruses and phages. According to the most popular classification, there are three types of CRISPR/Cas systems. Type II CRISPR/Cas system is most commonly used and consists of three components: an endonuclease (Cas9), a CRISPR RNA (crRNA), and a transactivating crRNA (tracrRNA). In dentistry, its role in identification of causative organisms or faulty gene in various oral pathologies ranges from oral cancer to dental caries per se. CRISPR can treat these oral diseases either by modulation or gene knockout of causative complex bacterial populations or faulty genes. Although treatment of oral diseases has started at research level, the practical application of CRISPR gene will not only eradicate the dental diseases at grass root level but also will revolutionize the dental practice per se.

Cryotherapy: A prodigy in endodontics

Pratik Parag More

Sardar Patel Post Graduate Institute of Dental and Medical Sciences, Lucknow, Uttar Pradesh, India

There is a constant evolution in the field of dentistry to deliver the best possible treatment for the patient. There is a constant search for new therapies to enhance patient's experience and instill a sense of confidence in the patient. Cryotherapy is a long-standing approach that has been applied in various fields including endodontics. Cryotherapy involves reducing the tissue temperature for curative purposes. Its mechanism of action in reducing pain involves decreasing the tissue temperature and reducing the flow of blood and metabolic activity. In dental practice, cryotherapy reduces edema and postoperative pain. Cryotherapy is used to control the bleeding from the vital tissues. In endodontics, shaved sterile water ice (0°C) is placed over directly or indirectly exposed pulp tissue, followed by irrigation with EDTA. This has shown to release a number of growth factors that promote matrix secretion, odontoblastic differentiation, and tertiary formation. Non-steroidal anti-inflammatory drugs or corticosteroids can help to reverse the inflammatory process and control pain but these medications have some side effects. To overcome these side effects Cryotherapy has been used as a non-pharmacological alternative for the management of postoperative endodontic pain which is one of the most common encountered entity by the dentists. It can also be used to improve the surface hardness and thermal stability of metal during manufacture of various endodontic instruments. Therefore, Cryotherapy could be contemplated as an uncomplicated, harmless, and cost-effective therapy having various applications in the field of endodontics.

Smart dentin replacement

Nikhil Mahaveer Yengure

PDU Dental College, Solapur, Maharashtra, India

Flowable composite resins are widely used in clinical practice. Bulk Fill flowable resins with improved mechanical and chemical characteristics have recently been introduced. SDR, developed by Dentsply, is the first posterior composite for dentin replacement combining the handling properties of a flowable composite with minimal shrinkage stress. As a result, it can be placed in increments of up to 4 mm. The 'Smart Dentin Replacement' layer is applied as a base in Class I and II cavities following the use of a conventional dentin/enamel adhesive. Smart dentine replacement (SDR) is a Bulk fill composite. These composites are low-viscosity materials with the reduced percentage of inorganic filler particles and higher amount of resinous components. Consequently, the polymerization process leads to volumetric contraction, but with minimal stress contraction. Flowable composites, with their low elastic modulus compete with stress development, potentially helping to maintain the marginal seal of the restoration. SDR is readily workable and adaptable to cavity walls and their use can reduce marginal defects in restorations. SDR offers interesting advantages in everyday practice, because it allows dentists to provide their patients with high-quality aesthetic posterior restorations in a cost-effective way. This review poster enlighten various aspects of bulkfill flowable composite resin materials.

Introduction: During carious attack release of acids by bacterial products cause demineralization and dissolution of enamel forming early carious lesion known as white spot lesion. There are various materials and technique have been used for remineralization. Recently use of self assembling peptides P114 has been introduced for enamel remineralization which adopts biomimetic approach where it forms a matrix 3D scaffold for de novo synthesis of hydroxypatite crystals. Mechanism The peptide P114 at low ph (causing early carious lesion) triggers self assembly of peptide in form of ß-sheet in 1D, having alternate sequence of hydrophobic and hydrophilic aminoacids, which further undergoes self assembly to form nanotapes which gets twisted and exhibit helical structure. Moreover nanotapes interlink to form nanoribbons, exhibiting a saddle curvature to decrease the bending and twisting of tapes and promote stacking, which results in formation of nanofibrils. The stable fibrils by edge to edge forms fibers, resulting in formation of scaffold which serves as matrix for denovo synthesis of hydroxypatite crystals. Conclusion the initial study suggests self assembling peptides may have promising and predictable result in treatment of remineralization of enamel and dentin.

Metascope: Augmented reality in real time practise

Priyamvada Pankaj Yadav

Sardar Patel Post Graduate Institute of Dental and Medical Sciences, Lucknow, Uttar Pradesh, India

Endodontics is confined to narrow and complex operating space as it deals with miniscule anatomy. As a result, intricate cases demand higher visual acuity and magnification. Many magnification devices such as dental loupes, surgical operating microscopes, endoscopes, and orascopes have been introduced out of which surgical loupes and dental operating microscope (DOM) became more popular in recent years. Surgical Loupes are available in several forms such as flip-up loupe, through-the-lens (TTL) loupe etc. The main reported advantages of dental loupes are comfort in vision and improved work accuracy while the main disadvantage was difficulty in visual measurement, limited range of magnification, and incorrect posture while working resulting in discomfort to the operator. On the other hand, Dental operating microscopes seems to offer wider range of magnification, better ergonomics. Nonetheless, major shortcomings are its lack of portability and cumbersome adjustment to the operating field. Therefore to eliminate shortcomings of both the devices metascope has been launched in dentistry which is one of its kind wearable overhead microscope claiming to provide wider range of motion, optical image stabilization, better ergonomics and big data files storage for case review and education purposes. It works on principles of augmented reality where peripheral view along with the operating field can also be perceived aiding in better visual acquity and operators eye adjustments. Its overhead wearability makes it easier to handle. This poster represents details about the novel device “Metascope” which could revolutionize the approach of magnification in conservative dentistry and endodontics.

Basavaraju Pavani Yesaswani, Mohammed Sameena

Gitam Dental College and Hospital, Visakhapatnam, Andhra Pradesh, India

Regenerative endodontic procedures have been perceived as valuable adjuvants to conventional strategies while treating necrotic immature permanent teeth. Scaffolds are three dimensional structures used inside the root canal. They provide micro environment allowing migration, proliferation, adhesion, and differentiation of stem cells into odontoblasts resulting in thickening of dentinal walls and root development. A wide variety of scaffolds both natural and synthetic are available. Natural scaffolds mimic the host tissue and contribute to biocompatibility. Synthetic scaffolds are reproducible and offer control over degradation rates. For successful treatment outcome a suitable scaffold should be selected that will act as a reliable guide for tissue regeneration. So, the aim of present poster presentation is to discuss about various types of scaffolds, their use in regenerative endodontics and to analyze the material with best clinical results.

The unsolved mystery: Herbal versus conventional irrigants

Ruhani Goyal

National Dental College and Hospital, Dera Bassi, Punjab, India

Introduction: Endodontic treatment failure may occur due to different causes such as persistence of bacteria, root canals that are poorly cleaned and obturated, improper coronal seal and untreated canals. The main reason for endodontic failure is the presence of some species of bacteria inside the root canal system. It has been observed that E. faecalis is the most frequently isolated species in cases of failed endodontic treatment with high prevalence values reaching upto 90%. Root canal irrigants aid in achieving disinfection in canal spaces. Sodium hypochlorite has been the gold standard for debridement and elimination of microorganisms and their toxins. Despite its fulfilment of desirable properties including availability and low cost, there has been concerns regarding its noxious effect such as allergic reaction, staining of instruments, irritation to periapical tissue, inability to remove smear layer, and has an undesirable smell and taste. So herbal alternatives can be advantageous in such situations. Aims and Objectives: To compare the antimicrobial efficacy of herbal extracts i.e, Turmeric and Triphala with the conventional irrigating solutions against E. faecalis. Materials and Methods: The study sample will be divided into three groups according to irrigating solution used i.e, Group 1 – Turmeric, Group 2 – Triphala, Group 3 – Sodium Hypochlorite. Agar well diffusion assay method will be used to determine the antimicrobial efficacy of these three groups against E. faecalis. Results: Study in progress.

CANUI – Innovative ultrasonic powered irrigation

Kadam Shubhangi Radhakisan

Pandit Deendayal Upadhyay Dental College, Solapur, Maharashtra, India

Root canal infections are typically polymicrobial and involve strong bacterial interactions. The main goal of endodontic treatment is to eliminate the infected tissue, bacteria and to fill the complex anatomy of the root canal system. Irrigation of the root canal system is an essential step in the endodontic treatment. Two important factors should be considered during irrigation: (a) delivery of irrigant to the entire root canal system and (b) capability of debriding areas not accessible by mechanical instrumentation. Continuous apical negative ultrasonic irrigation is designed for cleaning and disinfecting the root canal system. The device combines characteristics of the negative-pressure cleaning systems and continuous ultrasonic irrigation systems. The device consists of a body connected to an ultrasonic unit through the lower end. From the top this body emerges a steel macro-cannula (diameter of 0.75 mm) and a micro-cannula (0.3 mm) inserted into a macro-cannula. This micro-cannula is constructed using nickel–titanium and can adapt to the anatomy of curved root canals. CANUI technique is effective in removal of smear layer at apical third of root canal. Also it shows better performance in removing Ca(OH)2 intracanal medicament from the apical third area of the root canals. It is called “negative apical pressure,” because it applies suction rather than forceful injection to consistently provide the gold standard in care of patients.

A vast majority of these diseases have significantly affected the healing process in general and also have shown negative impact in the healing of periapical tissues. Though in cases of apical periodontitis, root canal treatment is performed optimally, complete healing of bone or reduction in the size of apical radiolucencies does not occur and can lead to endodontic failures. Because, the biological mechanisms involved in this resolution are substantially influenced by genetic factors and the systemic health status of the patient, which interfere with the repair of periapical tissues, by increasing the susceptibility of the host to infection, and/or impairing the immune response, maintaining the inflammatory process and periapical bone resorption even after Root canal treatment. Thus, considering this it becomes imperative for us as endodontist to understand the root cause behind the impact of systemic diseases on periapical healing at the molecular level, so that appropriate management protocols can be tailor made according to individual health status. Hence, the purpose of this poster presentation is to depict the evidence based association between systemic health status and the outcome of endodontic treatments, the interrelationship between periapical lesions and various systemic disorders along with the biological mechanisms involved.

Bioglass – A multifaceted wonder!

Sruthi Kapu

Gitam Dental College and Hospital, Visakhapatnam, Andhra Pradesh, India

Bioactive glass is an inorganic amorphous, calcium, sodium phosphor-silicate material, which contains fivefold ratio of Ca/P. The bioactive properties make bioglass applicable to several clinical applications involving the regeneration of hard tissues in medicine and dentistry. In dentistry, its uses include dental restorative materials, mineralizing agents, as a coating material for dental implants, pulp capping, root canal treatment, and air-abrasion. The chemistry of bioactive glass mimicks the natural hard tissues composition and has a bioactive role in the regeneration. Various commercially available bioactive glass are Bioglass 45S5, BonAlive, Novabone and 19-93B3 bioactive glasses. This glass has shown promise in inducing apatite formation when brought into contact with saliva or any physiological fluid. These apatites constitute either hydroxyapatites, or fluorapatites, if fluoride was incorporated into the chemical composition of the glass structure. Fluoride-containing glasses have 'smart' properties, with increased remineralization activity in low pH environments. Consequently, it has variously been added to toothpaste, prophylactic gels and dental materials to treat enamel demineralization. Based on in vitro findings, bioactive glasses may be capable of enhancing enamel remineralization more effectively than other topical remineralizing materials. It also appears to provide clinical success in managing dentinal hypersensitivity with toothpaste containing 2.5% to 7.5% concentrations of 45S5. Nevertheless, there is limited clinical research in relation to the effectiveness of bioactive glasses in inducing remineralization. Hence, this poster is aimed to highlight the expanded applications of bioglass in the field of restorative dentistry and endodontics.

Advancements in endodontic irrigation devices

Ruchi Vashisht

Denta School at PGIMER, Chandigarh, India

The foundation of successful endodontic therapy is based on the removal of all pulpal tissue, dentinal debris, bacteria and their endotoxins from the root canal. Endodontic success can be achieved by thorough chemo mechanical debridement of the canals. Basic chemo mechanical preparation with sodium hypochlorite leaves at least 40-60% of the initial bacterial counts in infected root canals, thus it highlights the need of more effective strategies and the need to maximize the effectiveness of irrigants that tend to induce better disinfection before filling the root canal system. The ability of an irrigant to be distributed within a closed system is dependent on canal anatomy, size and type of delivery system. The most challenging area remains the apical third due to the complex anatomy. The efficacy of the positive pressure irrigation is dependent on the depth of needle penetration and volume of irrigation. However, as efficiency increases by placing the needle closer to the apical foramen, the chance of extrusion of the solution is higher resulting in severe periapical tissue damage and post operative pain. In order to overcome this critical limitation, new delivery systems have been developed demonstrating better and safer irrigation. The aim of this review is to give a brief description of endodontic irrigation devices and their efficacy in root canal therapy.

Guided tissue regeneration in endodontics – A boon or a bane

M. Krupaa Sharan Balaji

Gitam Dental College and Hospital, Visakhapatnam, Andhra Pradesh, India

Regeneration is the reproduction or reconstitution of a lost or damaged tissue through the formation of a new one that can reproduce the form, structure and function of original tissues. Tissue regeneration is a complex process that needs a sequence of molecular events, such as cell adhesion, migration, multiplication and differentiation. The indications of tissue regeneration are regeneration in teeth with necrotic pulp and immature apex where pulp space is not needed for post/core, and absence of allergy to the medicaments to be used. The success of tissue engineering depends on three basic pillars: cell responsiveness; molecular induction and scaffolds. The Guided Tissue Regeneration (GTR) is a technique used in dentistry that aims at tissue and bone regeneration, or to repair damaged tissue. It is based on the perception that tissues are capable of self-reconstitution if appropriate conditions are provided. GTR therapy, which was introduced in the 1980s, has been widely used to regenerate lost tissues from periodontal disease, such as the periodontal ligament and alveolar bone. It has also been used in the apical surgeries as a concomitant treatment during the management of endodontic-periodontal lesions. In addition, GTR techniques are used in the management of mandibular defects, implants, intra-bony defects and vital pulp therapy. This poster is aimed to highlight the expanded applications of guided tissue regenerative therapy in the field of endodontics.

Polyvinylidene fluoride membrane: The evolution in endodontics

Shalu Shukla

Babu Banarasi Das College of Dental Sciences, Lucknow, Uttar Pradesh, India

Absorbent dental points, also known as paper points (PPs), were patented in 1958. It is primarily designed to dry canals, in order to seal off the canal spaces. This leads to good adhesion of sealers to dentinal wall canal and obturation materials. It is known that root canal infection is a polymicrobial infection both by gram-positive and negative bacterial species. The most important virulent factor of these gram-negative bacterial species is LPS. It is also known as endotoxin, is commonly involved in root canal infection. Therefore, endotoxin reduction and elimination are critical. Different root canal disinfection protocols have been tested against endotoxin in infected root canals, but they failed to eliminate endotoxins. Paper points showed less effect of eliminating the endotoxins. To overcome this white polyvinylidene fluoride membrane (PVDFM) which is one of the most promising materials because of properties such as chemical resistance, thermal stability, and robust strength. An advantage of the positively charged PVDFM tested here over the PPs is the capacity to remove negatively charged impurities. Endotoxin is negatively charged above pH of 2, a positively charged membrane might help remove endotoxin. Aside from the charge interaction, there is a hydrophobic interaction of the lipid A structure of the endotoxin and the hydrophobic membrane, which helps remove endotoxin. In this poster presentation I will be presenting about the PVDFM.

Aayuka Raj

People's Dental Academy, Bhopal, Madhya Pradesh, India

Context: One of the factors that may influence sealer bond strength to dentin is nature of intracanal medications. Calcium hydroxide (CH) pastes, when used as medicament, cannot be completely eliminated from root canals. Residual medicament affects penetration of sealers into root canal dentin wall. Aim: To evaluate the effect of Calcium hydroxide base as endodontic intracanal medicament on bond strength of epoxy and MTA based sealer to root canal dentin. Materials and Methods: In this in-vitro study, 60 single rooted human mandibular premolar were prepared using Protaper rotary system. The specimens were divided into a control group (without intracanal dressing) and an experimental group receiving CH. Intracanal dressing was removed after 3 weeks. Then samples of each group were divided into sub groups (n=10) and obturated with gutta percha and different sealers, Group-1- Control Group, Group-2- AH Plus, Group-3- MTA based. After 1 week, slices of 1 +/- 0.1 mm thickness were obtained from mid roots of teeth in each sub group and push out test was used to measure the bond strength. Slices were examined using stereoscopic microscope at 30x to determine the mode of failure. Statistical Analysis: All data were analyzed using Tukey-post-hoc test. Results: Overall, calcium hydroxide dressing reduced bond strength, but the reduction was significant only for AH Plus. It showed the highest bond strength for all roots to the other groups. G1, G3 showed similar bond strength values. Conclusion: The calcium hydroxide dressing had negative effect on bond strength.

Conventional stamping technique versus modified stamping technique in direct composite restoration

Nihad Mohammed

S Nijalingappa Dental College, Bagalkot, Karnataka, India

Biomimetics is the main aim of dental restorative treatment, as dental practitioner commit to restoring the natural contour and function of the original tooth. It is important to achieve a harmonious occlusal and cusp-fossa relationship in posterior tooth cavity restoration. However, rebuilding accurate tooth morphology using a direct composite restoration technique requires experience and time. Hence the stamp technique for direct composite restoration was introduced. However, as the opaque resin material is used to make a stamp and opaque teflon tape is laid on the tooth surface, accurate placement of the stamp is becomes difficult. To overcome this, a modified stamp technique was introduced in which a transparent bite resgistration material was used to form an occlusal stamp. Since the stamp is optically transparent, it is not necessary to remove it before light curing. Also, compothixo was used which alters the viscosity of the composite resin. This technique ensures accurate restoration of occlusal anatomy, avoids the formation of an oxygen-inhibited resin surface layer, time spent finishing will be shortened, good cusp-fossa relationship will be obtained, degree of voids in final restoration is reduced and also long term success can be achieved. The aim of this poster is to bring focus on modifications made in stamping technique and its application in conservative dentistry.

Biomimetic materials: A boon in restorative dentistry

Amit Balki

HSRSM Dental College, Hingoli, Maharashtra, India

Traditional approaches to treat damaged, decayed teeth require more aggressive preparation to place a strong stiff restoration. The emphasis is on the strength of the restoration, but no attention is placed into the function and biomechanics of the restored tooth. By ignoring this critical aspect, it is no surprise that complications such as tooth fracture occur more frequently and future treatment becomes more aggressive and invasive. So begins the restorative dental cycle in which the teeth are ultimately lost from successive treatments. With Biomimetic dentistry, only the damage and decay is removed from the teeth, and the final restoration is bonded to the remaining healthy natural tooth structure. Bio-mimetic dentistry is the art and science of restoring damaged teeth with restorations that mimic natural teeth in appearance, function, and strength. Biomimetic materials and methods will revolutionize the future of dentistry with the synergistic confluence of advances in signalling pathways underlying morphogenesis and lineage of stem/progenitor cells.

Contacts and contours

Mahammad Shabnam, Vignesh B. Kasal

Krishnadeveraya College of Dental Sciences, Bengaluru, Karnataka, India

Human teeth are designed in such a way that the individual tooth contributes significantly to their own support as well as collectively the teeth in th arch to support the stomatognathic system. Failure to preserve and respect the relationship of tooth with its surrounding not only causes premature failure of restoration but also periodontal problem as well as initiation of Caries around the adjacent tooth structure. The health of the periodontal the periodontal tissues is dependent on properly designed restorative materials. Overhanging restorations and open interproximal contacts should be addressed and remedied during the disease disease control phase of periodontal therapy. Regarding restorative margins, undoubtedly it is preferable if marginscan remain coronal to the free gingival margin. Obviously, subgingival margin placement is often unavoidable. However care must be taken to involve as little of the sulcus as possible. A clear understanding of the interproximal relationship will help the clinician to preserve these structures in a much better manner. To achieve an ideal contact, a clinician should have adequate knowledge of the ideal tooth forms and configuration of the proximal area so as to reproduce them with ideal restorative materials.

Nanobots – A small wonder

Disha Sharma

MCODS, Manipal, Karnataka, India

Nanotechnology has revolutionized all aspects of health including the dentistry. Nanorobotics is the technology of creating machines or robots at or close to the microscopic scale of a nanometer. The use of nanorobots may advance biomedical intervention with minimum invasive procedure and help patients who need constant body function monitoring. Dental nanorobots might use specific motility mechanism to penetrate human tissue with navigation precision, acquire energy and sense to manipulate their surrounding in real time. Although there could be many treatment modalities in dentistry, treatment possibilities might include the repair of carious teeth and remove blemishes of the tooth. Dental nanorobots could be placed intracoronally for non-vital tooth bleaching for pulpal regeneration inducing anesthesia. They can also remove hypersensitivity completely by remineralisation of dentinal tubules. They could be well used for aesthetic purpose also. They can swim in pulp chamber and canal to prevent the inflammation and also control infection in the canal. Nanorobotics has strong potential to revolutionize dentistry with improved accuracy, predictability, safety, quality of care and speed of diagnosis and treatment. Although research into nanorobots is still in its primitive stages, the promise of such technology for its use in future generation is endless.

Bioactive glass: The end is the new beginning

Shreya S. Patil, Neevika Singh

Krishnadeveraya College of Dental Sciences, Bengaluru, Karnataka, India

Bioactive glasses are silicate-based and can form a strong chemical bond with the tissues. These biomaterials are highly biocompatible and can form a hydroxyapatite layer when implanted in the body or soaked in the simulated body fluid. The first bioactive glass introduced in 1969 was a sodium, calcium, and phosphorus silicate glass. Currently, there are different types of bioactive glass, such as silicate-based glass and phosphate-based glass. Bioactive glass is an excellent material from the perspective of material properties. Because of its bioactivity and biocompatibility, the basic concept of applying bioactive glass in bone repair is to use a scaffold to act as a 3D template to guide bone regeneration. It has been applied in wide-ranging fields, especially in the use of bone grafts, scaffold, disinfectant of the dental root canal and coating materials of dental implants. The main advantage of bioactive glass in bone augmentation and repair is its high reactivity when in contact with bone surface and the most well known capability of bioactive glass is the bonding ability to bone as well as stimulation of bone growth. Bioactive glass can mineralize dentine tubules to relieve tooth sensitivity. Bioactive glasses can also be used to modify different biocompatible materials that need to be bioactive. This study reviews the significant developments of bioactive glasses in clinical application, especially dentistry. Furthermore, we will discuss the field of bioactive glasses from beginning to the current developments, which includes processing methods, applications, and properties of these glasses.

Procedural errors in endodontics and it's management

Nahid Khan

Chandra Dental College and Hospital, Dharsania, Uttar Pradesh, India

Endodontics is the branch of dentistry that is concerned with morphology, physiology and pathology of the human dental pulp and periradicular tissues. It helps us to maintain natural integrity of the teeth by removing microbial flora and cleaning of root canals followed by restoration of the teeth. Procedural errors in endodontics or alternatively any mistake that occurs at some point in the process of root canal treatment can be a result of factors which the operator has both control as well as no control over. Lack of knowledge of instruments or its poor application in clinicals can lead to a number of accidental errors during the root canal therapy. The preventive measures and management of these mishaps is must for the success of endodontic procedures. Thus in this poster different types of endodontic procedural errors with their management will be discussed.

Posterior indirect adhesive restorations

Raghu Pratap Thapa

Amrita School of Dentistry, Ernakulam, Kerala, India

Aim: To identify the indications for adhesively cemented restorations. Provide step-by-step protocol for clinicians. New cavity preparation principles are based on morphological considerations in terms of structure (dentin concavity and enamel convexity). Discuss previous preparation concepts that were not designed for adhesive restorations and were not conservative. The novel cavity shape consists of continuous inclined plane cavity margins (hollow chamfer or concave bevel) on axial walls. A 1.2 mm thick butt-joint preparation is performed in the interproximal box and on the axial walls when the margins are apical to the equatorial line. The occlusal surface is anatomically prepared, free of slots and angles. It is suggested to avoid shoulder finish line preparation around cusps, occlusal slots, and pins, as they are less conservative, incompatible with adhesive procedures, and involve unnecessary dentin exposure. The clinical advantages of this new “anatomic” preparation design are 1) improving adhesion quality (optimising the cutting of enamel prisms, and increasing the available enamel surface); 2) minimising dentin exposure; 3) maximising hard tissue preservation (the cavity being designed for cementation with reinforced composite resins, improvement of flow, and removal of excess material); 4) optimisation of esthetic integration due to the inclined plane design, which permits a better blending at the transition area between tooth and restoration. These preparation principles may be effectively used for all adhesively cemented restorations, both according to traditional concepts (inlay, onlay, overlay) and new ones (additional overlay, occlusal- veneer, overlay-veneer, long-wrap overlay, adhesive crown).
