摘要:

目的探讨牙科手术显微镜结合超声工作器械进行根管再治疗的临床效果。方法选取需要进行根管再治疗的111例患者的124颗患牙164个根管为研究对象,使用显微超声技术进行再治疗,统计根管再治疗的成功率。结果124颗患牙中,103颗完成了根管再治疗并获得临床成功,其成功率为83.06%;按根管数计算,164个根管有136个治疗成功,成功率为82.93%。按根管数计算,去除根管钙化物和取根管内塑化物的成功率分别为85.29%和83.33%,寻找遗漏根管和去除根管桩的成功率分别为86.67%和100%,取根管内分离器械和去除根管内台阶的成功率较低,均为66.67%。结论显微超声技术在牙髓病治疗中的应用为根管再治疗提供了有效的治疗手段。

Abstract:

Objective To explore the use of dental operating microscope with ultrasonic instruments in root canal retreatment. Methods 164 root canals in 124 teeth of 111 patients who need root canal retreatment were treated under dental operating microscope(DOM) with ultrasonic instruments, then the success rates were calculated. Results Both 136 root canals with a success rate of 82.93% from 164 root canals and 103 teeth with a success rate of 83.06% from 124 teeth were managed successfully. The each category of the retreated teeth was 85.29% for calcified canals, 83.33% for canal subjected to resinifying therapy, 86.67% for misunderstood root canals, 100% for canals blocked by post, and 66.67% for both root canals blocked by instrument fragments and ledged. Conclusion The use of microscope and ultrasonic instruments was proved to be an effective way in the root canal retreatment.
