Abstract

Aim: To compare the effectiveness of Apex Locators and Endomotor with built-in Apex Locators for determining the working length in root canal treatment.

Methods: A total of 120 patients were randomly assigned to three groups: Group 1 (Root ZX Mini Apex Locator), Group 2 (Minipex Apex Locator), and Group 3 (Endopilot Endomotor with built-in Apex Locator). Working length was determined using respective devices, followed by canal preparation and radiographic confirmation with a master cone.

Results: There was no statistically significant difference in working length determination between Apex Locators and Endomotor with built-in Apex Locators. Acceptable working length was achieved in 105 out of 120 cases.

Conclusion: The Root ZX Mini, Minipex, and Endopilot demonstrated comparable efficacy in determining working length during root canal treatment. These devices offer reliable alternatives to traditional radiographic methods, providing clinicians with accurate measurements and contributing to successful treatment outcomes.
