目的 探讨非创伤性充填技术 (ART)治疗老年牙根面龋的可行性。方法 对昆明某社区及楚雄地区 5 0 1名 60～ 75岁老年人牙根面龋进行调查 ,筛选符合要求患牙 113个作研究。试验组 :使用非创伤性充填技术充填治疗 ,对照组 :使用简单旋转器械 +Ketac -molar玻璃离子充填材料充填 ;结果 分别观察 1年、2年后根面龋的治疗成功率 :试验组为 80 .77%及 73 .91% ,对照组为 82 .98%及 76.77% ;试验组与对照组结果无显著性差异。结论 使用改进的、粘接性强的玻璃离子充填材料 ,ART方法能够代替传统方法治疗牙根面龋。该方法对中、小城镇、农村 ,山区及交通不便的地区更适用
Objective To explore the feasibility of non-invasive filling technique (ART) for treatment of root caries in the elderly. Methods A total of 510 dental caries in a community from 60 to 75 years old in a community of Chuxiong and Chuxiong were screened and 113 cases of adulterated teeth were screened. The experimental group was treated with non-invasive filling technique. The control group was filled with Krotac-Molar glass ion-filled material using simple rotating instruments. The success rate of treatment of root caries at 1 year and 2 years was 80 .77% and 73 .91% in the control group and 82.98% and 76.77% in the control group respectively. There was no significant difference between the experimental group and the control group. Conclusion The ART method can replace the traditional method of treating root decay using an improved, highly adhesive glass ionomer. The method is suitable for medium and small towns, rural areas, mountainous areas and areas with limited transportation
