Abstract

Bacterial microleakage around restorations is considered the principal cause of pulpal inflammation associated with restorations. The rationale for using cavity disinfectant is based on its antimicrobial properties but the cavity disinfectant may leave debris on dentin surfaces. The purpose of this study was to evaluate the effect of 2% chlorhexidine on shear bond strength and microleakage of adhesive restoration. 45 sound bovine teeth were used for the shear bond strength test and 30 for the micorleakage. For the experimental groups, 2% chlorhexidine was applied before the restorations, and was not for the control groups. The result from the this study can be summarized as follows; 1. No significant difference could be found in shear bond strength of each group. 2. No significant difference could be found in microleakage of each group.

Key Words: Chlorhexidine, Cavity cleanser, Shear bond strength, Microleakage
