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...

Lourival Melo Mota, s/n, Tabuleiro do Martins Maceió AL, CEP: 57072-970 E-mail: [email protected] Abstract Aim: ́ To evaluate comparatively the radiographic and electronic root canal length determination in primary molars. Methods: 128 canals from 66 primary molars were selected. The root of each tooth was cut open ...

AIM The purpose of this study was to compare the working length determination done using three methods, namely, apex locator (Foramatron D-10, Parkell), radiovisiography (Planmeca) and conventional radiography (Prostyle intra, Planmeca). MATERIALS AND METHODS In this experiment, to determine the working length, 35 single-rooted teeth were selected and each tooth was subjected to all the three...

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 ...

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 ...

one of the fundamental parameters for endodontic success. Traditionally this has been determined using radiography, but electronic apex locators are increasingly being used. Electronic apex locators reduce the number of radiographs required and assist where radiographic methods create difficulty. The use of an electronic apex locator in combination with the radiograph is greater precision in th...

INTRODUCTION The detection of possible root canal perforations caused during a metal post placement is frequently difficult to diagnose. The aim of this study was to investigate the accuracy of apex locators to diagnose such perforations. MATERIALS AND METHODS Thirty mesiolingual root canals of extracted mandibular molars were instrumented (30/.04) and a post space was prepared. A root canal ...

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...

An in vitro model was used to test a hypothesis that the manual (apex locator) and motor-driven (apex locator-controlled handpiece) operating modes of 3 newly developed apex-locator-controlled handpiece devices (Dentaport ZX, Endomaster, XSmart Dual) give the same working length. The depth of penetration of the file into the root canal was measured using a digital micrometer and the distance of...

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...
