Effects of chlorhexidine on dentin surfaces and shear bond strengths.

Abstract

This in vitro study examined the effects of chlorhexidine on dentin surfaces and on the bond strengths of composite to dentin. Scanning electron microscopy revealed that the chlorhexidine solution deposited debris on the surface and within the tubules of etched dentin but chlorhexidine had no significant effect on the shear bond strengths of composite to dentin using the All-Bond 2 adhesive system.
