摘　　要：目的评价牙科手术显微镜和超声器械联合使用处理困难根管的临床效果。方法选择因钙化、根管内充填物、根管内断针、遗漏根管以及根管穿孔等造成的困难根管221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治疗，统计成功率。结果应用牙科手术显微镜联合超声技术进行治疗的221个困难根管，总体成功率为77．4％（171／221）。其中，根管钙化82个，成功59个，成功率72．0％；根管内充填物76个，成功63个，成功率82．9％；根管内折断器械27个，成功20个，成功率74．1％；遗漏根管及c型根管24个，成功19个，成功率79．2％；根管侧穿12例，成功10个，成功率83．3％。统计学分析表明，各类型困难根管治疗成功率差异无统计学意义x2=3．16，P〉0．05）；其中各组之间成功率分别比较，差异亦无统计学意义（P〉0．05）。结论牙科手术显微镜和超声器械联合使用的疗效较理想，为临床处理困难根管提供了有效的方法。Objective To evaluate the effect of dental operating microscope and ultrasonic instruments on difficult root canals. Methods Totally 221 difficult root canals caused by calcification, filling materials, broken instruments, and omission of canals had ultrasonic tips under dental operating microscope. The success rate was calculated. Results One hundred and seventy-one difficult root canals were successfully managed with a success rate of 77.4%. No statistical differences were found （P 〉 0, 05）. Conclusion The use of dental operating microscope and ultrasonic instruments is proved to be an effective method in the management of difficult root canals.
