对比分析玻璃离子水门汀与复合树脂填充法治疗后牙牙体缺损的效果

Comparative analysis of the effects of glass ionomer cement and composite resin filling in the treatment of posterior tooth defects

目的 :对比分析玻璃离子水门汀(glass ionomer cement, GIC)与复合树脂(composite resin, CR)填充法治疗后牙牙体缺损的效果。方法 :回顾性分析80例后牙牙体缺损患者病例资料,根据不同填充方案分为对照组(n=40)和观察组(n=40),对照组接受GIC填充法,观察组接受CR填充法。随访2年后比较两组填充效果、美观度、咀嚼功能和不良事件发生情况。结果 :观察组填充成功率高于对照组(62.5%vs 40.0%),不良事件发生率低于对照组(5.0%vs 25.0%);修复后,两组咀嚼功能显著升高,且观察组咀嚼功能、美观度评分均高于对照组(均P <0.05)。结论 :与GIC比较,RC填充法治疗后牙牙体缺损可提高填充成功率,改善患者咀嚼功能,提高美观度。

Objective:To compare the effect of glass ionomer cement(GIC)and composite resin(CR)filling method in the treatment of posterior tooth defects.Methods:The data from 80 cases of patients with posterior tooth defects were retrospectively analyzed and divided into a control group(n=40)and an observation group(n=40)according to the different filling protocols.The control group received the GIC filling method and the observation group received the CR filling method.The results of filling,aesthetics,masticatory function and adverse events were compared between the two groups after 2 years of follow-up.Results:The success rate of filling was higher(62.5%vs 40.0%)and the incidence of adverse events was lower(5.0%vs 25.0%)in the observation group than the control group.After restoration,the masticatory function in both groups was significantly higher,and moreover the masticatory function and aesthetic scores were higher in the observation group than the control group(all P<0.05).Conclusion:Compared with GIC,the RC filling method for the treatment of posterior tooth defects can increase the success rate of filling,improve the patient’s masticatory function and enhance the aesthetics.
