This study evaluated the influence of tooth embedding media on the accuracy ofan electronic apex locator. The root canal length of 20 human mandibular canines was measured by inserting a 15 K-file into the root canal up to the apical foramen. The distance was measured with a digital caliper. The embedding media evaluated were alginate, saline, floral foam or gauze soaked in saline. Electronic r...

Introduction: Determining working length is regarded as an important step in root canal treatment, for which electronic apex locator can be applied. New apex locators are preferred, since they work via applying alternating current. Furthermore, the two factors of dentin specific resistance and capacitance seem to be effective principles in their operating. Therefore, this study aimed to determi...

INTRODUCTION Accurate determination of working length (WL) is a critical factor for endodontic success. This is commonly achieved using an apex locator which is influenced by the presence or absence of the apical constriction. Hence, this study was done to compare the accuracy of two generations of apex locators in teeth with simulated apical root resorption. MATERIALS AND METHODS Forty maxil...

Modern cardiac pacemakers are complex and heterogenous devices. The potential effect of electrically powered instruments on a patient's pacemaker function must be carefully evaluated before treatment. Interference with the pacemaker's function by the instrument depends on the specific type of pacemaker placed and the patient's dependence on it. A case is presented in which an electronic apex lo...

Practitioners face several challenges during the root canal treatment of teeth with wide or immature apices, one of which is working length determination. There is relatively little data regarding the value of radiography and electronic apex locator (EAL) use when root formation is incomplete, and supplementary measurement techniques may be helpful. This review considers length determination fo...

OBJECTIVES This study aimed to evaluate the accuracy of Root ZX in determining working length in presence of normal saline, 0.2% chlorhexidine and 2.5% of sodium hypochlorite. MATERIAL AND METHODS Sixty extracted, single rooted, single canal human teeth were used. Teeth were decoronated at CEJ and actual canal length determined. Then working length measurements were obtained with Root ZX in p...

AIM To evaluate the accuracy of Root ZX-II (J Morita Corp) apex locator in enlarged root canals with different root canal irrigants. MATERIALS AND METHODS 48 freshly extracted single rooted mandibular premolar teeth were used. The apical enlargement was done up to #45 K-file as the master apical file (MAF). The teeth were randomly divided into 4 groups and mounted in an experimental apparatus...

 Statement of Problem:Various methods have already been suggested to measure the working length in root canal therapy among which the use of paper point, tactile sense, radiography and electronic apex finder instruments can be named. Investigations on EAL (Electronic Apex Locator) indicate that these instruments can reduce the number of required radiography to a great extent. Moreover, in speci...
