AIM To evaluate ex vivo the accuracy of two electronic apex locators during root canal length determination in primary incisor and molar teeth with different stages of physiological root resorption. METHODOLOGY One calibrated examiner determined the root canal length in 17 primary incisors and 16 primary molars (total of 57 root canals) with different stages of root resorption based on the ac...

The effects of three dissolving agents on the accuracy of an electronic apex locator- (EAL-) integrated endodontic handpiece during retreatment procedures were evaluated. The true lengths (TLs) of 56 extracted incisor teeth were determined visually. Twenty teeth were filled with gutta-percha and a resin-based sealer (group A), 20 with gutta-percha and a zinc oxide/eugenol-based sealer (group B)...

The purpose of this study was to assess the effects of five electronic apex locators on pacemaker function in vitro. A Biotronik Actros DR+ pacemaker was evaluated at maximum sensitivity on a flat bench top. The pacemaker lead, electronic apex locator, and oscilloscope were connected across a 150-ohm resistor. Pace monitoring was carried out with a Biotronik EPR 1000 programmer and a Tektronix ...

Background: Successful root canal treatment is influenced by the apical extent of preparation and eventual filling. Achieving full working length until constriction, which usually 0.5 – 1 mm shorter than anatomical apex, crucial. Electronic apex locators were used to detect more accurately. There are six generations electronic in market. The selection appropriate irr...

Context: The accurate determination of working length (WL) has a major impact on the outcome root canal treatment. Aim: aim present clinical study was to compare accuracy using Cone Beam Computed Tomography (CBCT), Periapical radiograph and Electronic apex locator in teeth with periapical lesion. Settings Design: Randomised control trial. Materials Method: This conducted 30 patients an initial ...

BACKGROUND AND AIMS Determining the proper length of the root canals is essential for successful endodontic treatment. The purpose of this in vitro study was to evaluate the effect of file size on the accuracy of the Raypex 5 electronic apex locator for working length determination of uninstrumented canals. MATERIALS AND METHODS Twenty maxillary central incisors with single straight canals we...

background: accurate working length determination is a pre-requisite for a successful endodontic treatment. even with improved systems of working length measurement, different readings may be recorded in different electrolytes present in the canal. the purpose of this in vivo/ex vivo comparative study was to determine the accuracy in measuring the working length of root canal using direct digit...

Introduction: Knowledge of the internal anatomy of the tooth, apical foramen (AF) and mental foramen (MF) is considered a basic prerequisite before root canal surgical and non-surgical treatments. The aim this study is evaluation the distance and situation of AF & MF to anatomic apex of mandibular  premolar. Materials & Methods: In this cross-sectional study, CBCT images of mandibular p...
