Comparison Between Accuracy of Two Different Electronic Apex Locators in Determining Working Length of Root Canals: An In Vitro Study

Abstract

Background: Accurate determination of the working length of root canals is an important factor for the success of endodontic therapy. Aim: Two different apex locators namely Propex Pixi (Dentsply) and Canal Pro (Coltene) are used to determine the working length of root canals and their results are compared to determine their accuracy. Material and Methods: Twenty extracted permanent single-rooted teeth are used for the study. To determine the working length of root canals of each tooth, two different types of electronic apex locators, Propex Pixi (Dentsply) and CanalPro (Coltene) are used and their results are compared. Result: There was a significant difference in accuracy between the two apex locators in determining the working length of root canals (p-value <0.05). Canal Pro was more accurate than Propex Pixi.
