The article presents a study to evaluate and compare the clinical performance of four light curing composite resins at periods of one week and nine months by serial color photography and scanning electron microscopic (SEM) examination of replicas. It discusses the methodology and the materials used. 76 maxillary and mandibular molars and premolars were chosen for restorations made with the four composite resins P30, Ful-Fil, Heliomolar and Esttttilux-Posterior. Data was evaluated using the analysis of variance, Student-Newman-Keuls and Student-t tests. The one-week macrophotographic assessment gave satisfactory results for all the restorations except four restorations each of P30 and Ful-Fil. The SEM analysis showed significant differences in marginal adaptation among the four products.
