In this study the marginal discrepancies of 1000 amalgam fillings placed in human premolars and molars were evaluated. The results of the clinical evaluation of the fillings showed a great degree of agreement with other investigators. In 29.1% of the restorations the marginal gap was smaller than 100 microns. 47.7% of the fillings showed marginal gaps of less than 150 microns. Fillings with finished surfaces showed considerably smaller marginal discrepancies than those with unfinished surfaces.
在本研究中，对放置于人类前磨牙和磨牙中的1000个银汞合金充填体的边缘差异进行了评估。充填体的临床评估结果与其他研究者的结果高度一致。在29.1%的修复体中，边缘间隙小于100微米。47.7%的充填体边缘间隙小于150微米。表面光洁的充填体边缘差异比表面不光洁的充填体小得多。
