[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.

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.
