title: [Clinical evaluation for wear of composite resin in filling of molars].
abstract: To study the best evaluation method for wear of composite resins, 93 occlusal cavities of molars were restored with four kinds of light-cured composite resins, and three-year clinical research of wear analyses was performed using either direct evaluation method (USPHS) or indirect cast comparison (Leinfelder) method. The results suggested that the direct evaluation method for early wear of restorations would be less sensitive, but it remains the preferred system for the evaluation otherwise; the indirect method would be more reliable and sensitive, and numerical estimates of wear are more readily suitable for statistical analysis. The combination of direct and indirect methods will evaluate composite resin wear objectively and comprehensively.
