Abstract

Objective: A clinical study aims to record the distance to the apex and the accuracy of the working length measurements using an endodontic device integrated with an apex locator. Subjects and Methods: A clinical study conducted on 14 permanent teeth undergoing endodontic treatment using an endodontic device integrated with an apical locator E-ConnectS. The tooth access cavity was prepared, then the glide path and root canal preparation were achieved according to standard endodontic procedures. Digital periapical radiography with parallel technique was used as the imaging tool. The ImageJ software was employed to record the distance to the apical foramen and the accuracy of working length, which was categorized into three levels: "short," "acceptable," and "overfilled." Results: In the 14 cases, the mean distance to the apex was -0.48 ± 0.52 mm. The proportion of "acceptable," "short," and "overfilled" preparations were 78.57%, 14.29%, and 7.14%, respectively. Conclusion: Under these clinical study conditions, despite being designed to limit over-instrumentation, root canal preparation using an endodontic device integrated with an apex locator and evaluated with X rays images showed a high rate of "acceptable" working length measurements compared to the device's measurements. However, in challenging cases, clinicians should still perform apex locator in combination with periapical radiographs before obturation to prevent potential errors.
