Abstract
ABSTRACT Aim: The purpose of this study was to determine how effectively four distinct apex locators could diagnose root perforations in terms of accuracy and repeatability. Materials and Methods: Eighty mandibular premolars with a single root were instrumented. The distal face of the root was perforated at both the apical and middle thirds, five millimeters from the apical terminus. K-files connected to apex locators were used for detection on teeth set in an alginate-filled box. Results: The current research showed that all four apex locators accurately detected root canal perforations. Conclusion: This study’s findings show that all four apex locators were able to accurately and successfully identify root canal perforations.
