Context: Accurate working length (WL) determination is essential for successful root canal therapy. Aim: The aim of this study was to compare the difference between two different techniques in locating minor constriction using fifth-generation electronic apex locator. Settings and Design: A detailed protocol explaining the procedures of the study was submitted to the institutional ethics committee. Subjects and Methods: Forty extracted human permanent canine teeth were selected. WL was measured three times for each sample by three different examiners for both the conventional and experimental techniques at different time intervals. Interexaminers were blinded to their measurements, and the person who analyzed mean value was also blinded with techniques. Finally, radiographic working length was obtained using 15 size K-file. A size 20 K-file was cemented into the measured position with glass ionomer cement. Each tooth was viewed under a stereomicroscope at ×40 magnification. The distance from the file tip to the root apex was measured and calibrated to the nearest tenth of a millimeter. Statistical Analysis Used: Using Stata statistical software (Version 17, Statacorp, College Station, Texas, USA). The agreement between raters and techniques was determined using intraclass correlation coefficient "ICC" and Bland–Altman plot. Results: The "experimental method" (0.95, 95%) showed better agreement between the raters in comparison with the "conventional method" (0.93, 95%). Conclusions: The experimental technique showed perfect agreement between examiners in locating the minor constriction of the apical foramen. [ABSTRACT FROM AUTHOR] |
