摘要：

目的    评价显微超声技术配合K锉取出法取出根管内折断器械的临床效果。方法    对2005年3月至2010年6月在北京大学深圳医院口腔科就诊的根管内折断器械患者49例，应用显微超声技术结合K锉取出法取出折断器械，并对不同部位的根管内折断器械的取出情况进行分析。结果    49例根管内折断器械共取出37例，取出率75.5%；折断器械在根管上、中、下1／3的取出率分别为100%、87.5%、44.4%。结论    显微镜下应用超声技术结合K锉取出法是根管内折断器械取出较为理想的方法，根管下1／3折断器械取出率相对较低。

Abstract:

Objective    To evaluate the effects of K-files in combination with microsonic technique for the removal of fractured root canal instrument. Methods    A total of 49 cases of intracanal fractured instruments at Department of Stomatology in Peking University Shenzhen Hospital from March 2005 to June 2010 were analysed. K-files were applied to try to remove the fractured instruments and success rates were analysed according to the position of fractured instruments. Results    Totally 37 fractured instruments were completely removed with a success rate of 75.5%. The success rates of removing fractured instruments in coronal one-third，middle one-third and apical one-third of root canals were 100%，87.5% and 44.4% respectively. Conclusion    The combined use of K-files with microsonic technique is an effective way to handle complicated cases of intracanal fractured instruments.
