Working Length Determination Using Two Fifth-Generation Apex Locators With Radiovisiography: An In vivo Study
Year: 2025
Type: article
Study design: Observational Study
Abstract: Context: Accurate working length determination is essential for successful root canal therapy. This study compares the accuracy of two electronic apex locators-e-Magic Finder (EMF)-100 and WOODPEX I-with digital radiovisiography (RVG; Suni Ray) in determining root canal working length. Aims: To evaluate and compare the accuracy of EMF-100 and WOODPEX I apex locators with RVG in determining the working length of root canals. Settings and Design: , comparative observational study conducted in a clinical dental setting. The study included 30 patients (aged ≥15 years) requiring endodontic therapy on 45 mature permanent teeth. The aim was to evaluate and compare the accuracy of two electronic apex locators-EMF-100 and WOODPEX I-with digital radiovisiography (Suni Ray) in determining working length. Subjects and Methods: A total of 45 teeth from 30 patients (aged ≥15 years) requiring endodontic treatment were included. After obtaining consent and recording medical history, preoperative RVG images were taken using the paralleling technique. Working length was measured using three methods: EMF-100 apex locator (Group I), WOODPEX I (Group II), and RVG (Group III). Statistical Analysis Used: -test and Chi-square test. Results: Both apex locators demonstrated clinically acceptable accuracy. EMF-100 showed slightly better agreement with RVG than WOODPEX I. Conclusion: Both EMF-100 and WOODPEX I are effective for working length determination, with EMF-100 exhibiting slightly higher accuracy.
