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 cavi¡©ty 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 mi¡©croleakage of adhesive restoration.
45 sound bovine teeth were used for the shear bond strength test and 30 for the micorleakage. For the experi¡©mental 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.
