老年根面龋四种修复方法的临床疗效观察

Observation on Clinical Efficacy of Four Methods for Repairing Root Caries in the Elderly

目的:比较4种方法修复老年根面龋的临床疗效。方法:选择141例60岁及以上患者的240颗根面龋患牙分为4组,分别采用FX-Ⅱ玻璃离子直接充填(A组)、光固化纳米复合树脂直接充填(B组)及排龈后FX-Ⅱ玻璃离子充填(C组)、排龈后光固化纳米复合树脂充填(D组)4种方法修复根面龋,术后随访1年。结果:充填后1年A组、B组、C组和D组的成功率分别为83.3%、81.7%、86.7%和96.7%,其中D组显著高于前三组,差异有统计学意义(P<0.05),而前三组之间比较差异无统计学意义(P>0.05)。结论:对累及龈缘及龈下的老年根面龋用排龈后光固化纳米复合树脂充填修复效果好。

Objective： To compare the clinical efficacy of four methods for repairing root caries in the elderly.Method： 240 teeth of 141 elderly patients（ ≥ 60 y） with root caries were randomly divided into 4 groups, group A was treated by FX- Ⅱ glass ionomer（non-gingival retraction）, group B was treated with light cured composite resiu（nou-gingival retraction）, group C was treated with FX- Ⅱ glass ionomer（gingival retraction）, and group D was treated with light cured composite resin（gingival retraction）, the patients were followed up for one year.Result： The successful rate of group A was 83.3%, group B was 81.7%, group C was 86.7% and group D was 96.7% after 1 year.Group D was significantly different from the other three groups（P〈0.05）, and there were no significant differences between group A, group B and group C（P〉0.05）.Conclusion： Light cured composite resin with gingival retraction used in margin and subgiugival root caries in the elderly is effective.
