An overview of electronic apex locators: part 2
British Dental Journal, 2013A number of electronic apex locators are available for use during endodontic treatment. The use of third and fourth generation electronic apex locators (EAL) are recommended to help clinicians determine the apical limit of the root canal system (RCS). The presence of different irrigating media in the RCS does not impact significantly on the performance

An in vivo evaluation of Endex electronic apex locator
Journal of Endodontics, 1993Because of technical problems and hazards of radiation, dentists have desired alternative ways to determine the working length during root canal therapy. Attention has turned to electronic devices for measuring root canal length. Several such devices are now available.

A clinical evaluation of the Endocater—An electronic apex locator
Journal of Endodontics, 1991The purpose of this study was to evaluate the accuracy of an electronic apex locator, the Endocater, in determining the location of the apical constriction or cementodentinal junction (CDJ). Measurements made by the Endocater were also compared with the adjustments recommended by an experienced endodontist.

Accuracy of electronic apex locater-controlled handpieces
Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2009An in vitro model was used to test a hypothesis that the manual (apex locator) and motor-driven (apex locator-controlled handpiece) operating modes of 3 newly developed apex-locator-controlled handpiece devices (Dentaport ZX, Endomaster, XSmart Dual) give the same working length.

An overview of electronic apex locators: part 1
British Dental Journal, 2013To effectively carry out root canal therapy, the clinician must accurately determine the apical limit of the root canal system as well as the position of the canal terminus. Its position can be estimated using a variety of techniques, including radiographs, tactile feedback from endodontic instruments and electronic apex locators.

Use of an electronic apex locator on a cardiac pacemaker patient
Journal of Endodontics, 1996Modern cardiac pacemakers are complex and heterogenous devices. The potential effect of electrically powered instruments on a patient's pacemaker function must be carefully evaluated before treatment. Interference with the pacemaker's function by the instrument depends on the specific type of pacemaker placed and the patient's dependence on it.

An in vivo evaluation of root ZX electronic apex locator
Journal of Endodontics, 1996The Root ZX has been introduced recently as a device capable of performing accurately in the presence of sodium hypochlorite, blood, water, local anesthetic, and pulpal tissues. The Root ZX was used to locate the apical foramen in 26 root canals of vital teeth.

In vitro evaluation of the reliability of the endex electronic apex locator
Journal of Endodontics, 1998A new generation of electronic apex locators (Endex) that operates in moistened canals has been developed lately. An experimental comparison of this apparatus with the real, tactile, and radiographic measurements of the root canal length has been conducted.

In Vitro Evaluation of the Accuracy of Three Electronic Apex Locators
Journal of Endodontics, 2004The accuracy of three electronic apex locators (EALs) (Justy II, Root ZX, and Neosono Ultima EZ) is evaluated, together with the concordance of the measurements obtained by two different operators. Twenty single-root human teeth were used, sectioning the crown to gain access to the root canal.

Effect of Electronic Apex Locators on Cardiac Pacemaker Function
Journal of Endodontics, 2002The purpose of this study was to assess the effects of five electronic apex locators on pacemaker function in vitro. A Biotronik Actros DR+ pacemaker was evaluated at maximum sensitivity on a flat bench top. The pacemaker lead, electronic apex locator, and oscilloscope were connected across a 150-ohm resistor.
