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).
自1981 - 1982学年以来，爱荷华大学儿童牙科学系已在儿童磨牙中放置了约2000个复合树脂/窝沟封闭剂或预防性树脂修复体。当这些儿童再次前来检查或治疗时，会对他们的修复体进行留存、维护和质量评估。结果令人鼓舞：超过80%的窝沟封闭剂材料“完整无缺”；超过98%的复合树脂修复材料被评为相当令人满意（“阿尔法”类别）。
