This study is evaluating the clinical performance of a small particle bimodally filled hybrid proprietary composite resin and a dentin bonding system. This composite resin system is being employed for the restoration of class II carious lesions in posterior teeth. Its performance will be compared to that of a conventional amalgam. Fifty restorations of each of the two materials will constitute the study. Each restoration will be evaluated for clinical performance using a standardized method. Also, an attempt is being made to quantify any loss of material due to surface disintegration or wear using a recently developed scale and device.

本研究正在评价一种小颗粒的临床性能 双模态填充混合专利复合树脂和牙本质粘结 系统 这种复合树脂系统被用于修复 后牙II类龋损的可能性 它的性能将是 与传统的汞合金相比。 每种50份 这两份材料将构成研究报告。 每一次修复， 使用标准化方法评价临床性能。 此外， 正在尝试量化由于表面损坏而造成的任何材料损失。 使用最近开发的秤和装置测量磨损或崩解。
