Determination of location of root perforations by electronic apex locators

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 1996
This study was conducted to evaluate the accuracy of two electronic apex locators, the Sono Explorer Mark 2 Junior (Hakusui, Osaka, Japan) and Apit 2 (Osada, Tokyo, Japan) in detecting root perforations. The adequacy of radiographs for identifying root perforations was also assessed.Thirty-two extracted human teeth were perforated in the middle third ...

In Vivo Evaluation of ProPex Electronic Apex Locator

Journal of Endodontics, 2007
The aim of this in vivo study was to evaluate the performance of ProPex apex locator after extirpation and in presence of different irrigation solutions: 2.5% NaOCl, 0.9% NaCl, and 0.2% chlorhexidine gluconate solutions. Twenty-seven single-rooted human teeth scheduled for extraction with mature apices were selected for this study.

Investigation of Apex Locators and Related Morphological Factors

Journal of Endodontics, 2010
The purpose of this study was to investigate the ability of three electronic apex locators (EALs) to detect the minor foramen and morphological influencing factors relative to working length determination.Three hundred fifty-six extracted teeth were decoronated, and the coronal portion of the canal was flared. The distance between the major foramen and

In Vitro Comparison of Three Electronic Apex Locators

Journal of Endodontics, 2010
The purpose of this study was to compare the accuracy of the Root ZX II Apex Locator (RZX), the Elements Apex Locator (ELE), and the Precision Apex Locator (PAL).Forty single-rooted extracted teeth were decoronated and the root canals coronally flared.

Electric pulp tester and apex locator barrier technique

Journal of Endodontics, 1993
Use of the electric pulp tester and the apex locator during assessments of pulp vitality and root length determination involves bacterial cross-contamination of the metal surfaces of the probe tip and lip clip inserts which contact the oral hard and soft tissues. Reuse of these endodontic aids necessitates the sterilization or disinfection of the metal

An overview of electronic apex locators: part 2

British Dental Journal, 2013
A number of electronic apex locators are available for use during endodontic treatment. The use of third and fourth generation electronic apex locators (EAL) are recommended to help clinicians determine the apical limit of the root canal system (RCS). The presence of different irrigating media in the RCS does not impact significantly on the performance

An overview of electronic apex locators: part 1

British Dental Journal, 2013
To 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.

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.

Consistency of Apex Locator Function: A Clinical Study

Journal of Endodontics, 2009
The 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.
