title: Clinical evaluations of composite resin restorations in primary molars: a 4-year follow-up study.
abstract: A total of 96 composite resin restorations were placed in primary molars. After 4 years, 44 restorations were examined. The wear rate was similar to that of enamel in primary molars. The material had excellent radiopacity and color-matching properties.
