Abstrakt: An electronic apex locator(EAL) is a device used to measure the working length (WL) of the root canal space(RCS) and proved to be a great help to the endodontist reducing radiation exposure of both patients and clinicians and providing accurate reading for the WL. Evolution of different generations of EAL helped to eradicate the shortcomings of the previous generations providing precise measurement of the WL. Electronic Apex locators are used to detect any perforations, furcation involvement, also used to detect horizontal fractures, also to detect internal or external resorption. With so many uses, it is still contraindicated in patients with pace makers and inaccurate reading in canals with common irrigants like Ethylenediamine tetraacetic acid and sodium hypochlorite. It requires dry or partially dry canals to give readings with accuracy. It also gives inaccurate reading in the presence of semi-conductive materials and hence the canals should be free of them. Though it provides almost precise measurement of the WL it cannot be replaced with radiographs but can be used as an adjunct with it. Pre- and post-operative radiographs are still necessary for the success of the endodontic treatment as it provides an idea for any periapical lesion and degree of curvature of roots. Acceptance of an electronic apex locator to determine the correct WL has still not gained approval worldwide. Lack of exposure to the technology by the operator, inadequate knowledge of the root canal anatomy and cost of the instrument are also the factors for it not gaining worldwide acceptance.
