Using the information from remake request slips in a dental school's predoctoral clinic, we examined the short-term survival of Class II resin composite restorations versus Class II dental amalgam restorations. In the student clinic, resin composite is used in approximately 58 percent of Class II restorations placed, and dental amalgam is used in the remaining 42 percent. In the period examined, Class II resin composite restorations were ten times more likely to be replaced at no cost to the patient than Class II dental amalgam restorations. A total of eighty-four resin composite restorations and six amalgam restorations were replaced due to an identified failure.
利用牙科学院的修复申请单上的信息，我们研究了 II 类树脂复合修复体与 II 类牙科汞合金修复体的短期存活率。在学生诊所中，树脂复合材料大约用于 58%的 II 类修复体，而剩余的 42%使用牙科汞合金。在所研究的时期内，II 类树脂复合修复体比 II 类牙科汞合金修复体更有可能在无需患者付费的情况下被替换，替换的概率是后者的十倍。共有 84 个树脂复合修复体和 6 个汞合金修复体因已确定的失败而被替换。
