Aim: To evaluate the effect of D-Solv Gel, chemomechanical caries removal method on bonding of self-etching adhesives to caries-affected dentin, in comparison to the standard rotary-instrument caries removal method.
Materials and Methodology: Twenty extracted carious human molars exhibiting frank cavitation intodentin were used. Ten teeth were randomly divided into two groups, according to the caries excavation methods :(i) D-Solv Gel and (ii) a round steel bur. After caries removal, eachgroup underwent self-etching adhesive application and resin composite buildup. Bonded specimens were sectioned into beams for shear bond strength testing under universal testing machine.
Results: Results of the one-way ANOVA revealed that the shear bond strengths were not affected by the factor “caries excavation method” (p > 0.05).The method of caries removal had no effect on the bond strengths of one-step self-etching adhesive to residual dentin following caries excavation (p > 0.05).
Conclusion: The chemomechanical caries excavation methods did not affect bonding of self-etching adhesives to caries-affected dentin, in comparison to rotary caries excavation method.
