Eighty Class V non-undercut cervical abrasion lesions were restored using four dentine bonding agents and composite resin. The restorations were examined over a three-year period, and the cumulative loss rate calculated each year. Marginal staining at each year was assessed using a standardized photographic method. The loss rate of restorations increased generally over the three-year period, reaching 30 to 60 per cent for the four products. Marginal staining also increased for all four products over the three-year period.
使用四种牙本质粘结剂和复合树脂修复了80例V类非倒凹型颈部磨损病变。对修复体进行了三年的观察，并计算每年的累积损耗率。每年使用标准化摄影方法评估边缘染色情况。在三年期间，修复体的损耗率总体呈上升趋势，这四种产品的损耗率达到了30%至60%。在三年期间，所有四种产品的边缘染色情况也有所增加。
