X-ray micro-analysis was used to determine the elemental composition of the tooth, amalgam, and base material of ten aged, amalgam-restored, posterior teeth after they had been fractured across the amalgam-tooth interface. Subsequently, replicas were used to remove marginal seal material from each interface for examination by x-ray micro-analysis. The results show that P and Sn were present in all marginal seal material analyzed. Ca, Cl, Cu, Fe, S, and Zn were present in the marginal seals of various numbers of specimens.
采用X射线微分析法测定了10颗陈旧的、用汞合金修复的后牙在汞合金与牙齿界面处断裂后的牙齿、汞合金和基底材料的元素组成。随后，使用复制品从每个界面去除边缘封闭材料，以便通过X射线微分析法进行检查。结果表明，在所有分析的边缘封闭材料中均存在磷和锡。钙、氯、铜、铁、硫和锌在不同数量的标本边缘封闭处存在。
