摘要： 目的比较3种根管工作长度测量方法的准确性。方法选取2015年1月—2016年6月治疗的90例患者,232个根管随机分为3组,分别采用X线片、Raypex5型根尖定位仪和i-root型根尖定位仪测量根管工作长度。依据充填质量评估测得工作长度的准确性。采用SPSS19.0软件包进行统计学处理。结果X线组、Raypex5组及i-root组的根管充填成功率分别为88.5%、92.9%和96.1%,组间比较差异无显著性（P>0.05）。磨牙、前磨牙及前牙的根管充填成功率分别为92.5%、96.6%和95.2%,组间比较差异无显著性（P>0.05）。结论Raypex5型根长测定仪及i-root型根长测定仪的临床效果与传统的X线法相似,但可避免不必要的电离辐射,提高临床工作效率。

Abstract: PURPOSE: To compare the accuracy of measuring root canal working length with two different electronic apex locators and digital X-ray. METHODS: Ninety patients treated from January 2015 to June 2016 were selected, 232 root canals in total were randomly divided into 3 groups: X-ray group, Raypex5 group and i-root group. The accuracy of working length measured was assessed according to the filling quality of related main tips. The data were analyzed with SPSS19.0 software package for Chi-square test. RESULTS: The success rates for root canal filling of X-ray group, Raypex5 group and i-root group were 88.5%, 92.9% and 96.1% respectively with no significant difference between 3 groups (P>0.05). The success rates for root canal filling of molar teeth, premolar teeth and front teeth were 92.5%, 96.6% and 95.2% respectively with no significant difference between the 3 groups (P>0.05). CONCLUSIONS: The clinical effect of Raypex 5 and i-root electronic apex locators for working length measuring is similar to that of conventional X-ray, but the use of electronic apex locators can avoid unnecessary ionizing radiation and improve clinical efficiency.
