Abstract: The aim of the present study was to evaluate the accuracy of three different electronic apex locators in single-rooted teeth. Materials and methods were Sixty extracted human single-rooted permanent teeth were selected for this study. The actual working length was measured with visual technique by placing a size #15 k-file under magnification. Then, the canal lengths were measured electronically with RAYPEX 6, ROOT ZX II and using Propex II? electronic apex locators within ?0.5and ?1mm. The three readings were obtained by different observers for each sample by reinserting the No.15 K-?le, and measurements were obtained with the three Electronic Apex Locators. Results: The mean value of working length for RAYPEX 6 was 23.11 mm while Propex II and ROOT ZX II were 20.98 mm and 21.33 mm respectively. Conclusion: The Raypex 6 electronic apex locator is most reliable in the determination of working length, followed by the Propex II electronic apex locator and the Root ZX II electronic apex locator.
