经旁路通道处理根管内器械分离的临床分析

Clinical analysis of bypass approach for removal of endodontic instrument separation

目的:评价采用旁路通道法对发生器械分离的根管进行治疗的临床疗效。方法:选取23例发生根管内器械分离的患者,比较经旁路通道取出折断器械的实验组,及分离器械无法取出的对照组的治疗情况,并根据1年内随访资料进行临床疗效评价。结果:旁路通道组治愈率91.66%(11/12),常规根管治疗组治愈率45.45%(5/11),差异有统计学意义(P<0.05)。结论:通过建立旁路通道是治疗根管内器械分离的有效方法。

Objective:To assess the clinical efficacy of bypass approach for removal of a separated instrument from the root canal.Methods:Twenty-three cases of separated instrument in the root canal were included,and divided into experimental group managed with the bypass removal approach and control group treated with conventional protocol due to failure of removal of the broken instrument.The two groups were compared and evaluated concerning the clinical outcomes data collected in one year of follow-up.Results :The curative rate was 91.66%(11/12) for the patients managed with by bypass approach,and 45.45%(5/11) for the patients treated with conventional method.The difference was statistically significant (P<0.05).Conclusion:The bypass approach is effective for removal of the separated instrument from the root canal.
