Influence of chlorhexidine concentration on the durability of etch-and-rinse dentin bonds: a 12-month in vitro study.

Abstract

Chlorhexidine significantly reduced the loss of bond strength seen in control bonds. Since no bacterial growth was present in the aging conditions, the results of this study suggest that endogenous factors thought to degrade the adhesive interface can be inhibited by CHX. Further in vivo trials should confirm the role of CHX in bond durability.
