摘要/Abstract

摘要：

目的评价牙科手术显微镜和超声器械联合使用处理阻塞根管的临床效果。方法选择因钙化、器械分离、根管桩、塑化物等造成的阻塞根管236个为研究对象，在牙科手术显微镜下使用专用超声器械进行根管再通畅治疗，统计成功率。结果236个阻塞根管中，成功再通畅的根管有178个，成功率为75.4%。钙化根管再通的成功率为71.7%，取分离器械的成功率为81.1%，根管桩取出率为100%，塑化根管再治疗成功率为62.5%，取根管内充填物的成功率为84.1%。结论牙科手术显微镜和超声器械联合使用，为临床处理阻塞根管提供了有效的方法。

Abstract:

Faculty of Stomatology, Capital Medical University, Beijing 100050, China） [Abstract] Objective To evaluate the effect of using dental operating microscope and ultrasonic instruments in treating blocked canals. Methods The etiology of canal blockage included calcification, broken instruments, posts, resinifying, etc. 236 blocked canals were treated with ultrasonic tips under dental operating microscope. The success rate was calculated. Results 178 blocked canals were successfully managed with a success rate of 75.4%. The success rate of each category of the blocked canals were: 71.7% for calcified canals, 81.1% for broken instruments, 100% for canals blocked by posts, 62.5% for canals blocked by resinifying therapy, and 84.1% for canals blocked by filling materials. Conclusion The use of dental operating microscope and ultrasonic instruments is proved to be an effective method in the management of blocked canals.
