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 ...

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.

Consistency of Apex Locator Function: A Clinical Study
Journal of Endodontics, 2009The consistency of apex locators was determined by calculating the dysfunction frequency. Electronic working length (EWL) was determined in 507 patients requiring endodontic treatment. Different clinical parameters were recorded including tooth vitality, presence of obliteration, and metallic restoration.

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.

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.

The Ability of Two Apex Locators to Locate the Apical Foramen: An In Vitro Study
Journal of Endodontics, 2006The objective of this study was to compare the accuracy of the Root-ZX and Novapex electronic apex locators (EALs) in locating the apical foramen. Forty extracted human teeth were used. The coronal portion of each canal was flared using Gates Glidden drill. Canals were irrigated with 2.5% sodium hypochlorite.

[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.
