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.

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.

A study on the design and construction of Electronic Apex Locator

2016 International Conference on Biomedical Engineering (BME-HUST), 2016
Electronic Apex Locator (EAL) has been developed to determine the true apical foramen location and working length of root canals in endodontic treatment process. It has been long stories of EAL devices since the principle idea was first reported. Since then, many modified ideas and varieties commercial products of electronic apex locators have been ...
