An in vitro stereomicroscopic comparative evaluation of a combination of apex locator and endodontic motor with an integrated endodontic motor

Abstract

Objective: To compare the efficacy of an integrated apex locator and an apex locator and endodontic motor assembly in maintaining the working length when operated under autoreverse mode. Study Design: Thirty distobuccal roots of intact maxillary first molars were taken and access cavities were prepared. The teeth were divided into Group I: Prepared with TCM Endo V and Group II: Prepared with ProPex and NSK assembly. The instrumentation was ended in ProTaper F3 file, which was cemented in the canal. The roots were sectioned, observed under a stereomicroscope and the distance from instrument tip to the apical foramen was measured. Results: Mean difference in the deviation of two groups was 0.075 mm, P = 0.34 (>0.05) which was statistically insignificant when assessed with unpaired t-test. Conclusion: The assembly of ProPex-NSK Endo-mate DT and the apex locating endomotor TCM Endo V Nouvag are clinically acceptable. [PUBLICATION ABSTRACT]
