BACKGROUND Accurate determination of the apical terminus plays a significant role in the success of root canal therapy, but accuracy may be affected by the presence of accessory canals. OBJECTIVE To evaluate the accuracy of a ratio-based electronic apex locator for roots with simulated lateral canals. METHODS Forty-two single-rooted human teeth were randomly divided into 2 groups. For each ...
INTRODUCTION The purpose of this study was to compare the accuracy of working length (WL) measurements by using the Root ZX II, Apex NRG XFR, and Mini Apex Locator with rotary nickel-titanium (NiTi) instruments. METHODS Twenty-eight teeth had their WLs determined with each electronic apex locator (EAL) by using 0.04 taper ProFiles sizes 40-20 in a crown-down technique until WL was reached. Fo...
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 Determination of the canal working length with radiographs has many drawbacks. Electronic apex locators have been developed to overcome some of these problems. Recently, a newly designed apex locator called NovApex has been introduced. All the studies conducted to determine the accuracy of NovApex have been carried out in-vitro on extracted teeth. The aim of this in vivo study was ...
Objectives: to assess the consistency and accuracy of Electronic Apex Locator (EAL) (root ZXII) in individual canals and its association with other clinical variables. study Design: cross-sectional study. Place of study: Dental section of the Aga Khan University Hospital, Karachi, Pakistan. Materials and Methods: Working length was measured by EAL in 180 patients requiring endodontic therapy in...
AIMS The purpose of this study was to evaluate the accuracy of a new-generation electronic apex locator (iPex) to determine working length in primary teeth with or without root resorption as compared with the conventional radiographic method. MATERIALS AND METHODS A sample of 30 primary posterior teeth which are indicated for pulpectomy were selected for the study. After obtaining the informe...
introduction: the aim of this study was to evaluate the accuracy of two electronic apex locators (smarpex and novapex) in detecting apical perforation. materials and methods: after access cavity preparations, the working length was determined by the first examiner before and after perforation with a stereomicroscope by introducing a k-file size 10 into the canal and size 25 k-file up to the per...
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...
