【摘要】 目的 选择修复老年人后牙根面龋的理想方法和材料。方法 选择60例双侧后牙患根面龋的老年人为试验组1，双侧分别采用非创伤性充填技术和临床常规治疗方法预备洞型，以银粉玻璃离子充填。选择60例老年患者为试验组2，应用非创伤性充填技术，双侧分别用银粉玻璃离子和玻璃离子直接充填。随访观察1年。结果 试验组1中两种治疗方法修复成功率分别为88.33%和91.67%，差异无显著性(P>0.05)。非创伤性充填技术治疗痛苦感小。试验组2中两种材料的修复成功率分别为90%和75%，差异有显著性(P<0.05)。结论 非创伤性充填技术是修复老年人后牙根面龋较理想的方法，银粉玻璃离子是较理想的充填材料。

    【Abstract】 Objective To select ideal methods and materials to fill senile cement caries.Methods 60 old men were selected into group 1 who suffered from cement caries in both sides of maxillary or mandibular,treated by atraumatic restoration treatment and conventional treatment,respectively.All caries were filled by glass ionomer silver reinforced restorative.60 old men were divided into group 2,treated by atraumatic restoration treatment.One side was filled by glass ionomer silver reinforced restorative,and another was glass ionomer.The fillings had been followed up for one year.Results Group 1:the success rates of two methods were 88.33% and 91.67%,respectively.The difference was not statistically significant(P>0.05).Treatment pain seldom occurred in atraumatic restoration treatment group.Group 2:the success rate of glass ionomer silver reinforced restorative group was 90%,that of glass ionomer group was 75%.The difference was statistically significant(P<0.05).Conclusion Atraumatic restoration treatment is a ideal method for filling cement caries,glass ionomer silver reinforced restorative is a ideal material. ......
