Effect of cavity disinfection on bond strength to dentin

The application of a disinfecting step in cavity preparation and tooth restoration is gaining wider acceptance. This study examined the effect of two commercially available disinfecting agents on the shear bond strength to dentin using a fourth generation dentin bonding agent. The agent tested permitted an evaluation of both dry and wet bonding techniques. It was found that the commercial preparations did not adversely affect shear bond strength to dentin in either the dry or wet application.
