Abstract: Objective: The aim of this in vitro study was to evaluate the accuracy of the Root ZX II electronic apex locator (EAL) using hand stainless-steel file, nickel-titanium hand file and nickel-titanium rotary file. Methods: Twenty straight single-rooted maxillary central teeth were used. The actual working length (AWL) was measured by inserting a #15 K-file until the file tip was visible at 4x magnification. The file was removed from the canal and its length was measured using a digital caliper. For the electronic measurements, samples were fixed in glass recipients with plastic cover, containing 0.9% saline solution. The measurements were carried out using the Root ZX II and they were performed using a #15 K-file, NiTi hand file and a rotary Mtwo file. The files were attached to the EAL and during their insertion into the root canal the measurements were monitored until the display indicated "zero". The corresponding values of the difference between the AWL and the electronic measurement were recorded and submitted to ANOVA and Tukey test (α=0.05). Results: No statistically significant differences (p<0.05) was found among the tested files. Conclusion: It can be concluded that both stainless steel files and NiTi hand or rotary files are adequate to determine the working length using the Root ZX II.
