    The efficacy of two apex locators in determining the working length was assessed using 17 single-root natural teeth. The teeth were subjected to coronal access and insertion of Nitiflex K-files up to the root canal limit, with the measurement recorded in millimeters. Subsequently, two apex locators (I-root and Woodpex III) were used to determine the same working length. For the use of these devices, the oral environment was simulated by placing the dental pieces in an alginate mold, where a lip clip was also placed, and the electrode was connected to the endodontic file, closing the circuit. The data generated were recorded and tabulated using the Student's T-test and one-way ANOVA statistical tests. As a result, the actual working length of the dental pieces was 21.40 ± 2.23 mm, while the working length of the dental pieces evaluated with the I-Root and Woodpex III apex locators was 21.15 ± 2.34 mm and 21.28 ± 2.31 mm, respectively. In conclusion, no statistical disparity was found between the results (p > 0.05), with the largest difference between the actual and electronic working lengths being 0.25 mm.
