295 amalgam fillings in deciduous teeth and 150 amalgam restorations in permanent first molars were examined in 112 child patients. The functional loss of restorations was corded and present fillings were assessed in view of marginal integrity, anatomy and surface condition. For primary molar amalgams the 4-year survival rates "estimate" ist ein Schätzwert--wenn der Autor es so gemeint hat, muss "estimate" stehenbleiben, andernfalls heisst es "iate" (= Quote) were 67% for Class 1 restorations and for 55% Class 2 fillings. After 4 years of placement 78% of the Class 1 restorations in permanent first molars were still intact.
对112名儿童患者的295颗乳牙汞合金充填物和150颗恒牙第一磨牙的汞合金修复体进行了检查。记录修复体的功能丧失情况，并根据边缘完整性、外形和表面状况对现有的充填物进行评估。对于乳牙汞合金修复体，1类修复体4年的“估计”（如果作者是这个意思，“estimate”应保留，否则为“率”（=比例））生存率为67%，2类充填物为55%。在恒牙第一磨牙中，1类修复体放置4年后仍有78%完好无损。
