复合树脂加玻璃离子夹层修复老年后牙根面龋24例

Composite Resin and Glass Ionomer Cement Sandwich in Restoring the 24 Elderly Patients with Root Surface Caries

目的：观察评价复合树脂加玻璃离子夹层修复老年后牙根面龋的临床效果。方法：选取48例（共96牙）发生牙根面龋的老年患者并随机分为两组,24例患者（48牙）采用复合树脂加玻璃离子夹层修复作为观察组,24例患者（48牙）采用单独玻璃离子修复作为对照组,回访两组患者6个月-1年,观察修复后6个月及1年时的修复效果。结果：修复后6个月时,观察组24例共48牙成功牙数为46（95.83%）,对照组24例共48牙成功牙数为44（91.66%）,两组患者成功牙数无显著差异（P〉0.05）。修复后1年时,观察组24例共48牙成功牙数为46（95.83%）,对照组24例共48牙成功牙数为38（79.17%）,两组患者修复后1年时成功牙数有显著差异（P〈0.05）。结论：采用复合树脂加玻璃离子夹层修复老年后牙根面龋结合了两者优势,可明显提高修复效果,值得临床推广应用。

Objective：To evaluate the clinical repair effect of composite resin and glass ionomer dissection for caries. Methods：48 cases （96 teeth）, root surface caries in elder patients were randomly divided into two groups, 24 patients （48 teeth） using fixation of composite resin and glass ionomer as a sandwich technique as the observation group, 24 patients （48 teeth） separate glass ionomer to repair as a control group, a return visit two groups of patients 6 months to 1 year, 6 months after the repair was observed when repairing effect. Results：6 months after the repair, to observe the success of the number of teeth of the group of 24 patients by a total of 48 teeth for 46 （95.83%）, the success of the number of teeth of the control group, 24 cases of 48 teeth and 44 （91.66%）, the success of the number of teeth of the two groups of patients no significant difference （P〉0.05）. 1 year after the repair, the teeth of the observation group, 24 patients with a total of 48 teeth successfully for 46 （95.83%）, the success of the number of teeth of the control group, 24 cases of 48 teeth and 38 （79.17%）, 1 year after the repair of the two groups of patients successfully teeth had a significant difference （P〈0.05）. Conclusion：The composite resin and glass ionomer dissection repair old root surface caries combine both advantages, which can significantly improve the repair effect, is worthy of clinical application.
