Abstract:
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.
