introduction: despite being the gold standard as well as a routine technique in endodontics, radiographic working length (wl) determination owns many drawbacks. electronic apex-locators (eals) are recommended to complement radiographies. the aim of this study was to evaluate the perceptions of iranian general dental practitioners (gdps) towards using radiography and eal. methods and materials: ...

Numerous apex locator studies have been performed. Generally, they use only stainless-steel hand files for testing purposes. Today many clinicians use both stainless-steel and nickel-titanium files during the treatment of a case. Given the widespread use of nickel-titanium files, a comparison of the accuracy in determining length with an apex locator using stainless-steel and nickel-titanium fi...

INTRODUCTION The purpose of this clinical study was to compare the accuracy of working length (WL) determination using cone-beam computed tomography (CBCT), conventional periapical radiographies and electronic apex locator. METHODS AND MATERIALS This study was conducted during root canal treatment of 19 patients with a total of 30 single-rooted teeth diagnosed with apical periodontitis. After...

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...

Background Techniques with adequate accuracy of working length determination along with shorter duration of treatment in pulpectomy procedure seems to be essential in pediatric dentistry. The aim of the present study was to evaluate the accuracy of root canal length measurement with Root ZX II apex locator and rotary system in pulpectomy of primary teeth. Material and Methods In this randomiz...

BACKGROUND Cleaning and shaping of root canal system requires various irrigating solutions. The question is whether the presence of irrigation solution alters working length determination using apex locators. The purpose of this study was to compare the accuracy of Root ZX and i-Root apex locator for determining working length in the presence of different irrigating solution. MATERIALS AND ME...

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 ...

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 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...
