초록

The purpose of this study was to observe the longevity of amalgam and composite resin fillings in Korea. The number of placement of restorations was 760 amalgams and 415 composite resins. The amalgam restorations inserted because of primary caries were 61 % and replacement of amalgam restorations were 39%, and composite restorations inserted because of primary caries were 62 % and replacement of composite restorations were 38 %. The median longevity of failed amalgam restorations was 3 years and the madian longevity of failed composite restorations was 2 years. The main reason of replacement of amalgam and composite resin restorations was secondary caries.
