The aim of this study was to evaluate the effect of three retreatment solutions on the accuracy of four electronic apex locators, the Root ZX mini, the Mini Apex Locator, the Root ZX and the Elements Diagnostic Unit and Apex Locator. Forty extracted single-rooted human teeth were used in this study. The four electronic apex locators were operated according to the manufacturer's instructions to locate the 'apical constriction' in the presence of chloroform, orange solvent or eucalyptol in the canal. The accuracy of each apex locator was not affected by the type of retreatment solution present in the root canal. In addition, the accuracy of the four apex locators was similar in the presence of each of the tested solutions.
本研究的目的是评估三种再治疗溶液对四种电子根尖定位仪（Root ZX mini、Mini Apex Locator、Root ZX以及Elements Diagnostic Unit and Apex Locator）准确性的影响。本研究使用了40颗拔除的单根人牙。按照制造商的说明操作这四种电子根尖定位仪，以在根管内存在氯仿、橙色溶剂或桉叶油的情况下定位“根尖狭窄处”。根管内存在的再治疗溶液类型不会影响每种根尖定位仪的准确性。此外，在每种测试溶液存在的情况下，这四种根尖定位仪的准确性相似。
