Since the invention and application of rotary instruments, the operative treatment of carious lesions has often resulted in considerable removal of tooth structure. More recently, newer techniques for removal of carious dentine have been developed in an attempt to minimize this excessive tissue loss. Some of the technical available to excavate demineralised dentin clinically can be classified as mechanical and non-mechanical rotary and non-rotary and include dental hand pieces/burs, manual excavators, air-abrasion, air-polishing, ultrasonication, sono-abrasion, chemo-mechanical methods, lasers and enzymes. This paper addresses a technique in which carious dentin is treated with cansolv gel (chemo-mechanical caries removal) and using the conventional rotary instrument system for caries removal. SEM analysis of the treated surfaces of the two treatment groups was done. This was followed by composite core build up and strength testing (Instron Universal Testing Machine) to evaluate the efficacy of the above-mentioned methods. 28 recently extracted carious human molars were taken and divided into two treatment groups (Group I and Group II). Group I was subjected to carisolv treatment and group II was subjected to rotary instrument treatment. Shear bond strengths were measured following composite core build up and the results were analyzed statistically. The SEM study depicts more debris in group I and group II and the SBS values for group I and group II were 8.73 and 10.86 (mean) respectively. The statistical analysis depicts significant difference between the two treatment groups at 1% level (p<0.01). Cansolv though a step forward in the caries removal method, is not in a position to replace rotary instruments for caries removal. |
