流动性纳米修复剂修复老年人根面龋的临床疗效

Clinical effects of liquid nanocomposite treatment on root caries cases in elder patients

目的:观察流动性纳米修复剂修复老年人根面龋的临床效果。方法:360个患牙随机分为3组,分别用流动性纳米修复剂、玻璃离子水门汀、光固化复合树脂修复,随访2年。结果:3种材料修复成功率分别为96.67%、66.67%、82.50%。流动性纳米修复剂组优于光固化复合树脂组,光固化复合树脂组优于玻璃离子组,差异有统计学意义(P<0.05)。结论:流动性纳米修复剂是一种较理想的修复老年人根面龋的材料。

AIM： To observe the effects of liquid nanocomposite on the treatment of root caries in elderly patients. METHODS： Three hundred and sixty teeth with root caries were randomly divided into three groups, with 120 teeth in each group. The teeth were filled with liquid nanocomposite resin, glass ionomer cement and composite resin respectively. Filling effects were observed at 2-year follow-up. RESULTS： The respective success rates were 96.67% , 66.67% and 82.50% in liquid nanocomposite resin, glass ionomer and composite resin groups. Of the three groups, liquid nanocomposite resin group had the best outcome, and the effects of composite resin filling were clearly superior to glass inonomer cement treatment. The restorative effects of the three composites differed significantly （ P 〈 0.05 ）. CONCLUSION ： Liquid nanocomposite resin is an ideal filling material for root caries restoration in elderly patients.
