Introduction: Radiography is the most common method for measurement of working length, though it is not the ideal method because of technical problems, radiation hazard, superimposition of permanent teeth bud on primary teeth, and so on. Electronic Apex Locator (EAL) is a device for determination of working length. Therefore, this study aimed to compare the accuracy of an electronic apex locato...

INTRODUCTION The purpose of this study was to compare the accuracy of the Root ZX II Apex Locator (RZX), the Elements Apex Locator (ELE), and the Precision Apex Locator (PAL). METHODS Forty single-rooted extracted teeth were decoronated and the root canals coronally flared. Actual canal lengths were determined by inserting a #10 file until the tip was visualized (12.8x magnification) just wit...

Aim: The sixth generation apex locators served as an efficient diagnostic tool for detecting root perforations as these are based on the principle of impedance rather than the conventional gradient method. However, their diagnostic accuracy not evaluated well. In the existing study, we assessed and compared the efficacy of two apex locators for diagnostic perspective. Materials and Methods: A t...
