title: Use of optical standards for determining wear of posterior composite resins.
abstract: The results of a long-term clinical study of a posterior composite resin are reevaluated using the Moffa-Lugassy, the Vivadent, and the Leinfelder-Goldberg standards. Occlusion (ICI/Coe, England) was selected for the study, and the results obtained from three universities are compared. From these results, it is concluded that all posterior composite resins should be evaluated using the same optical standards.
