In vitro evaluation of the reliability of the endex electronic apex locator

Journal of Endodontics, 1998
A 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, 2004
The 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, 2002
The 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.

Evaluation of the accuracy of the neosono-D electronic apex locator

Journal of Endodontics, 1984
The efficacy of an electronic device to locate the apical foramen was evaluated in vivo in 24 mature and 5 immature root canals in human teeth. The results were obtained by direct microscopic and radiographic measurements. The device was found to be consistently accurate in mature teeth but inaccurate in immature teeth.

In vitro evaluation of the accuracy of several electronic apex locators

Journal of Endodontics, 1995
This study describes two tests of the in vitro accuracy of several models of electronic canal length measuring devices (ECLMDs) using a gelatin test model and extracted human teeth with fully formed apices. In part 1, four previously untested ECLMDs were used in dry canals after access and pulpectomy.

Clinical Efficacy of Electronic Apex Locators: Systematic Review

Journal of Endodontics, 2014
Apical constriction has been proposed as the most appropriate apical limit for the endodontic working length. Despite being the most used, some limitations are attributed to the radiographic method of working length determination. It lacks precision because it is based on the average position of the apical constriction.

Comparison of two electronic apex locators on human cadavers

Clinical Oral Investigations, 2015
The aim of this study on human cadavers was to compare the accuracy of two electronic apex locators (EALs) Dentaport ZX (J. Morita Corporation, Tokyo, Japan) and Raypex 6 (VDW, Munich, Germany).Twenty-two single rooted teeth of four human cadaver heads were scheduled for this study.

Efficient and effective use of the electronic apex locator

Journal of the Irish Dental Association, 2022
When used correctly, the EAL may expedite treatment, reduce the need for intra-operative radiographs and result in a biologically orientated chemo- mechanical preparation length that maximises the likelihood of a successful outcome.

[Electronic Apex Locator as a dental instrument].

Refu'at ha-peh veha-shinayim (1993), 2010
Electronic Apex Locators (EAL) have become widely used in the last decade. The first apex locator was introduced in 1962, based on a constant electrical resistance (6.5 K.) between the oral mucosa and periodontal ligament. The first and second generations of EAL were inaccurate and could not detect the apex in the presence of conducting fluids.
