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.
由两名经过培训的检查人员在基线时以及6个月、12个月和24个月时对修复体进行评估。在所使用的系统中，最高、最理想的评级为阿尔法。在24个月时评估的修复体中，99%在颜色匹配方面获得阿尔法评级，87%在洞缘无变色方面获得阿尔法评级，86%在解剖形态无丧失方面获得阿尔法评级。此外，在24个月的评估中，75%的修复体在边缘密合性方面获得阿尔法评级，91%在无继发龋方面获得阿尔法评级。总之，光固化复合树脂修复材料在用于乳磨牙时，在12个月和24个月的评估期内功能良好。
