The effect of irrigation solutions and file types on the accuracy of electronic apex locator: An in vitro study

To achieve success in endodontic treatment, working length can be accurately determined using an electronic apex locator. However, the accuracy of the apex locator is not always stable across different root canal environments. This study aims to evaluate the accuracy of the Apex ID, 4th generation of apex locator, under various irrigation solutioans and types of measuring files.
