OBJECTIVE The aim of this in vitro study was to compare the capacity of the Root ZX-II and Mini Apex Locator, electronic apex locators (EALS), to prevent overestimated working length. STUDY DESIGN Forty extracted human teeth were used for the study. The cervical portion of each canal was flared using Gates Glidden drills and the teeth were embedded in an alginate model. Canals were irrigated ...

OBJECTIVES Today many clinicians use both stainless-steel hand K-files and nickel- titanium rotary files during endodontic treatment. It is of great importance for the clinician to have confidence in the accuracy of an apex locator even if these files were used interchangeably. The purpose of this in vitro study was to evaluate the accuracy of the Raypex5 electronic apex locator using stainless...

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...

Introduction: There are few researches in literature that mention the use of the apex locator in deciduous teeth and working length is obtained through radiographies. Objective: The purpose of this research was to compare the radiographic and the electronic method to obtain the working length in deciduous molars. Material and methods: Twelve molar teeth were used. The specimens in the visual me...

INTRODUCTION The purpose of this in vitro study was to compare the accuracy of working length determination using the apex locator versus conventional radiography in C-shaped canals. METHODS AND MATERIALS After confirming the actual C-shaped anatomy using cone-beam computed tomography (CBCT), 22 extracted C-shaped mandibular second molars were selected and decoronated at the cemento-enamel ju...

INTRODUCTION This ex vivo study evaluated the accuracy of the Root-ZX electronic apex locator (EAL) (J. Morita, Tokyo, Japan) and the NovApex (Forum Technologies, Rishon Lezion, Israel) in determining the working length (WL) during endodontic treatment. MATERIALS AND METHODS Forty extracted single-rooted human teeth were selected for this study. The actual WL was measured with visual techniqu...

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 ...

introduction: success in endodontic treatment depends on various factors. among the most important factors, appropriate preparation of the root canal system and keeping periapical region intact as much as possible could be mentioned. these are achieved by determining the penetration depth of the instruments into the canal i.e. the working length. several methods are introduced for working lengt...

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...

BACKGROUND An in vivo comparative evaluation to determine the accuracy of working length between radiographic and electronic apex locators. AIM The study was aimed at evaluating the accuracy of electronic apex locator, to determine the working length of root canal, and to compare it with the radiographic method of working length determination. MATERIALS AND METHODS A total of 20 teeth selec...
