The article discusses the results of a study which compared the microtensile bond strength of teeth restored with four dentin bonding agents at the gingival and pulpal cavity walls of Class-II resin-based composite restorations. The four adhesives showed no significant differences in microtensile bond strength at the gingival wall versus the pulpal wall. Adhesives PQ1 and CFSE performed the best. There were more cohesive failures exhibited by the PQ1 samples.
