Effect of preflaring on Root ZX apex locators
Journal of Endodontics, 1999The Root ZX apex locator is an example of a generation of apex locators that identify the terminus of the canal by measuring a ratio between two electrical impedances. Studies have shown this device to have a high degree of accuracy. However, the manufacturer warns that the performance of these devices is limited by the presence of calcifications and ...

Interference of Electronic Apex Locators with Implantable Cardioverter Defibrillators
Journal of Endodontics, 2014The purpose of this in vitro study was to evaluate the potential electromagnetic interference of electronic apex locators (EALs) on implantable cardioverter defibrillators (ICDs).Four different EALs were tested for their ability to interfere with the correct function of 3 different ICDs.

[Electronic Apex Locator as a dental instrument].
Refu'at ha-peh veha-shinayim (1993), 2010Electronic 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.
