A clinical review of preventive resin restorations.

Since the 1981-1982 academic year, the University of Iowa Department of Pediatric Dentistry had placed approximately 2000 composite/sealants or preventive resin restorations in children's molars. When these children appeared again for examination or treatment, their restorations were evaluated for retention, maintenance, and quality. Results were encouraging: more than 80 percent of the sealant material was "all present"; and more than 98 percent of the composite restorative material was rated quite satisfactory (the "Alfa" category).
