Two-year clinical evaluation of light-cured composite resin restorations in primary molars

The restorations were evaluated at baseline, and at 6, 12, and 24 months by two trained examiners. In the system used, the highest, most desirable rating is Alfa. Of the restorations evaluated at 24 months, 99% had Alfa ratings for color match, 87% had Alfa ratings for no discoloration at cavosurface margins, and 86% had Alfa ratings for no loss of anatomic form. In addition, 75% of the restorations had Alfa ratings for margin adaptation, and 91% had Alfa ratings for no recurrent caries at the 24-month evaluation. In conclusion, the light-cured composite resin restorative material functioned well at the 12- and 24-month evaluation periods, when used in primary molars.
