A clinical, radiographic, and SEM evaluation of Class 2 composite restorations in primary teeth

Sixty class 2 composite resin restorations were placed in 22 children and evaluated at baseline, six months, and one year. Radiographs were used for evaluation, in addition to clinical examinations, photographs, and scanning electron micrographs of epoxy resin casts of retrieved teeth. It was concluded that radiographs are necessary to detect a large percentage of failures at the gingival margins of class 2 composites.
