Abstract

Background:  Evaluation of Micro-shear Bond toughness of Caries Affected Dentin Treated with Conventional, Smart Bur and Chemo-mechanical Technique using in vitro model. Materials and Method: Forty-five freshly extracted human maxillary and permanent mandibular teeth, due to periodontal reasons or impacted third molars, in which occlusal caries extending up to deep dentin but not involving pulp were collected and arbitrarily proportioned into three groups after sectioning along with caries removal was done, and a perpendicular 2-mm high resin composite rod was bonded using multi-mode adhesive and the bonded interface was tested for the micro-shear bond strength. The results, thus obtained, were statistically analyzed.  Results: One way (ANOVA) and Post hoc Tuckey’s test were used for carrying out statistical analysis. The result showed variation in bond strength values for each of the groups, with the lowest for smart bur group. Conclusion: Carie-care does not affect bond strength negatively and thus could be used as an alternative for caries excavation.
