摘　　要：目的:研究三联法(手感法、牙平均长度法和X线片法)测量根管工作长度的准确性及影响因素。方法:通过对40颗离体单根牙和96颗临床根管治疗患牙采用三联法测量工作长度,了解其准确度及影响因素。结果:三联法测定离体牙工作长度准确性专家组为82.5%,研究生组62.5%;临床测量准确度2组分别为87.1%和75.5%。操作者经验、冠根完整性及根尖周病变对三联法测量准确性有影响。结论:三联法测量工作长度能达到较满意准确度,但受临床经验等较多因素影响。Objective：To evaluate the accuracy and influence factors of a triple-united method used for the determination of root canal working length. Methods：Root canal working length was detemined by manual measurement, tooth average length and radiographic measurement （ triple-united method）. In vitro experiment was conducted in 40 teeth and clinical study in 96 teeth by experienced specialists and postgraduates. Results：The accuracy of triple-united method was 82.5% and 62.5% by spcialist and poststudents in vitro, 87.1% and 75.5% in clinic,respectively. The accuracy was interfered by experience of the examiner, tooth integrity and apical disease. Conclusion：Triple-united method can meet the clinic requirement in the determination of root canal length.
