[Amalgam fillings in the deciduous and mixed dentition--a post-treatment evaluation of service life and quality].

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.
