TL;DR: The macrophotographic evaluation revealed a satisfactory clinical appearance in the majority of restorations, however, scanning electron micrographic observations demonstrated that moderate-to-medium marginal degradation occurred during the first 2 years of clinical service.
Abstract: A 2-year study of the clinical performance of four posterior composite resins used for Class I and Class II restorations is reported. Seventy-seven obturations were reviewed from the patients selected for a previous 9-month study. Obturations were assessed macrophotographically and by scanning electron microscopic evaluation of marginal quality. The 2-year results were compared to those obtained at 9 months. The macrophotographic evaluation revealed a satisfactory clinical appearance in the majority of restorations. However, scanning electron micrographic observations demonstrated that moderate-to-medium marginal degradation occurred during the first 2 years of clinical service. Therefore the use of the products under investigation should be limited to selected cases in which esthetics is of primary concern.
