Tooth quarantine – Redefined

Anju S. Hussain

RKDF Dental College and Research Centre, Bhopal, Madhya Pradesh, India

Background: The rubber dam has been introduced to endodontics over past 120 years. It is obligatory in endodontics, so much so that endodontics should not be performed without a rubber dam. Its introduction is attributed to Dr. Sanford Christie Barnum, who in March 1864 demonstrated for the first time, the advantages of isolating the tooth with a rubber sheet. It is surprising that even today the use of rubber dam for endodontics among general dental practioners is low. Many reasons such as, time for rubber dam placement, cost of equipment and materials, difficulty in use and patient acceptance are some of the disincentives to rubber dam use given by the dentists. Aims: This presentation is intended to illustrate the advances in rubber dam materials and techniques and to discuss their possibilities to use in endodontics. Materials and Methods: Illustrating the various recent advancements in rubber dam materials and explaining selection, techniques and applications of each material according to different clinical situations, using typhodont jaw set and power point presentations. Conclusion: The use of rubber dam in endodontics has been unfortunately rejected by many in the profession. Many unfounded reasons for its use like, time for its placement, cost of equipment and materials, difficulty in use and patient acceptance are given by the dental practioners. However, recently by the introduction of many newer variations, its use in endodontics has been made easy.

Vonlays – A combination approach to veneers and onlay

Pallavi Sinha

Sharad Pawar Dental College, Wardha, Maharashtra, India

Along with the increase in dental awareness, there has been a growing trend in patients who are opting for teeth retention rather than extraction. So post endodontic restorations play a significant role in dictating restorations longevity. Root canal treatment often suffer from extensive loss of tooth structure because of access cavity preparation, caries removal ,replacement of restorations and trauma. Along with the availability of newer high strength materials and processing technologies like CAD CAM and heat pressing, dental professionals are now able to produce esthetics, high strength restorations that blend seamlessly with natural tooth and withstands posterior occlusal forces. One such approach to minimal invasive dentistry is, Vonlay which is a combination restoration. The presenting table clinic demonstrates vonlays that can be used as an alternative to full coverage crowns in damaged posteriors and post root canal treatment. Both chairside and through laboratory highly aesthetic, high strength restorations are able to be quickly fabricated. Thus vonlay is a befitting example of how dentistry has applied current science to clinical situations to provide patients with better dentistry following the minimal invasive dentistry. The presenting table clinic exhibit indications, contraindications technique of tooth preparation and potent materials that could be used in its fabrication.

Magnobot: The microbial terminator

Srishti Grover, Niharika Prasad

Manipal College of Dental Sciences, Mangalore, Karnataka, India

The success of endodontic treatment is dictated by appropriate shaping, disinfection and three dimensional obturation of the root canal system. Almost 24-50 million root canal procedures are carried out every year, of which more than 10% are reported to fail. A major cause of failure of root canal treatment is the persistence of bacteria deep within the dentinal tubules, which are difficult to remove through conventional as well as state-of-the art techniques, primarily due to the complex and narrow topography of the dentinal tissue. Recently, nanobots have been developed which are small enough to fit through the dentinal tubules and reach the bacteria to kill it. They are helically shaped and made from silicon dioxide with an iron coating. This enables them to be controlled by a magnetic field and taken to depths of up to 2,000 μm, where the field can be tweaked to make the robots generate heat and kill off the bacteria, offering a safe and potent way to improve the success of standard root canal treatments. Dental nanorobots, today somewhat fictional, will bring significant benefits in the field of endodontics, contributing to achieving painless, quick and high precision dental treatments. In this table clinic, we will be highlighting various aspects of nanobots in endodontics and its future implications.

Forced orthodontic extrusion of a traumatized tooth with tissue master concept

Aakash Kumar

All India Institute of Medical Sciences, New Delhi, India

Background: In teeth with crown root fracture the remaining tooth structure below the fracture line effects the prognosis of the rehabilitation of the traumatized tooth. If the fracture line is not exposed, sub-gingival preparation margins and sub-crestal defects are liable to violate the biological width leading to a compromised periodontal health. Moreover, a design with no ferrule has a major impact on clinical success. To overcome these issues surgical crown lengthening and orthodontic extrusion prior to restorative procedures have been suggested in the literature . These treatment manoeuver are complex and hard to perform in everyday practice. Aims: To demonstrate a convenient method of forced orthodontic extrusion with tissue master concept. Materials and Methods: A model simulating a tooth with crown root fracture will be used. Split dam adaptation would be performed. A fibre-reinforced composite based bar will be adhesively bond to the root surface of the endodontically treated tooth . A second bar will serve as an abutment and will be placed between the adjacent teeth with a flowable composite. Forced orthodontic extrusion will be done, with 5/16” medium thickness elastics. Photographic representation of each step of a clinical case will also be displayed. Statistical Analysis: Not applicable. Results: Not applicable. Conclusion: Not applicable.

Stereolithography – A 3D printing technology

Charu Sonegare, Ujjvala Vinay Pyati

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

Three dimensional printing is a new promising technology in the field of dentistry. It started in 1980s when Charles Hull printed a three dimensional object. He then created the first 3D printer that used the technique of stereolithography. It is an additive manufacturing method in which an object is formed by laying down successive layers of material. Conventional substractive manufacturing techniques like milling are known to create high wastage which can be minimized using techniques in adjunct with additive manufacturing. 3D printing is clearly the best available digital processing method for this purpose. Its higher efficiency, passivity, flexibility and superior material utilization makes it distinct from other techniques. Also, it is time saving, less technique sensitive and many models can be prepared using this technique. Various dental prosthesis and restorations can be printed using different methods of 3-D printing like selective laser sintering or melting (SLS) (SLM), stereolithography, fused deposition modeling (FDM), multijet printing, digital light processing, colorjet printing and photopolymer jetting. 3D printing combined with digital intra oral scanning and CAD/CAM designing aids in fabrication of crowns, bridges, various orthodontic appliances, fabrication of indirect restorations? like inlays, onlay, fabrication of template for guided endodontics, repair of bony/soft tissue defects, dental pulp regeneration, educational models, autotransplantation,? night guard trays, template for restoration of fractured anterior teeth. 3D printed instruments are now becoming a reality. They are at present being used in medical field. So fabrication of dental instruments can be seen in near future.

Dental pulp stem cells: A new frontiers in regenerative medicine

Samanvitha Kanimilli, K. V. Neema

HKES Nijalingappa Dental College, Gulbarga, Karnataka, India

The fields of regenerative medicine and stem cell-based tissue engineering have the potential of treating numerous tissue and organ defects. Stem cells are undifferentiated mesenchymal cells that are capable of differentiating into various specialized cell types. Dental pulp stem cells are unique population of cells embedded in pulp cavity which offers promising source of stem cells for numerous regenerative procedures. The developmental pathway that generates the dental pulp stem cells results in a cell type that can contribute to the regeneration of numerous tissue types. Their natural functions in the production of odontoblasts to create reparative dentin supports applications in dentistry in the regeneration of tooth structures such as in dental pulp regeneration, periodontal regeneration, tooth reconstruction and bone tissue engineering. Besides their applications in dentistry, they are also being investigated for the repair of tissues outside of the tooth such as in orthopaedics, neurology, angiogenesis, endocrinology and immunomodulatory therapies for inflammatory diseases. The ease of isolation, viability, non-immunogenic, high proliferation rate and multipotency advantages of dental pulp stem cells from extracted teeth makes them a better alternative to the stem cells derived from other parts of human body. A large body of literature is building to support the clinical use of dental pulp stem cells in dentistry, orthopaedics and other applications. Hence, the aim of this table clinic is to focus on highlighting the importance of dental pulp stem cells in dentistry and beyond dentistry.

Forces acting on a class 2 restoration

Nupur Bhatnagar

Hitkarini Dental College and Hospital, Jabalpur, Madhya Pradesh, India

Designing a structure for the oral environment is quite challenging and demanding, as, the functional and parafunctional loads must be accommodated and the aesthetic component should also be considered. Teeth are subjected to many forces during use and much higher on the posterior teeth than anterior teeth. A restored tooth under load tends to transfer stresses differently than a normal tooth. This table clinic demonstrates forces acting on class 2 restoration and how to prevent its debonding/fracture.
