The clinical performance of a new adhesive resin system in class V and IV restorations

A clinical trial was initiated to examine a new adhesive system introduced for dentin and enamel bonding of composite resins. Restorations were placed in patients in need of Class V and Class IV restorations. The clinical study was designed to examine the adhesive system in restorations involving mostly dentin surfaces (Class V) and in a population of restorations mostly involving enamel surfaces (Class IV). At the 1-year recall period, the adhesive system had demonstrated excellent adhesive qualities in both types of cavities. Initial results also showed improvement over previous adhesive systems with regard to moisture sensitivity and variation in dentin composition.
