Working Length Determination of Root Canal of Young Permanent Tooth: An In vitro Study
BACKGROUND Determination of correct working length is one of the keys to success in endodontic therapy. AIM The aim of this study was to evaluate the diagnostic efficacy of various methods to determine working length of root canal. MATERIALS AND METHODS Tactile method was assessed using digital radiography and compared with electronic method using apex locator. A total sample of 30 single r...
متن کاملA study on electric method for measuring root canal length.
As a fundamental study on the electric method for measuring root canal length, the various factors which affect the measured impedance were investigated using a wide range of frequencies. 1) The impedance between two saliva ejectors in contact with the oral mucosa near the bilateral premolars in the lower arch generally showed low values. The difference between the maximum and minimum measured ...
متن کاملRadiographic versus electronic root canal working length determination.
PURPOSE The aim of this ex vivo study was to compare the accuracy of radiographic and electronic root canal length determination methods, compared with actual root canal length obtained with stereomicroscope. MATERIALS AND METHODS Thirty extracted single-rooted permanent teeth were used for this study. After access preparation, actual length (AL) of the root canal were determined for each too...
متن کاملEffect of Intra-Canal Direct Current Electric Stimulation on Orthodontic Tooth Movement: An Experimental Study in Canines
Objectives: The purpose of this study was to evaluate whether intra-canal application of controlled direct electric current (DEC) could accelerate the amount of orthodontic tooth movement (OTM) in young adult mixed breed dogs. Methods: Fourth premolars of both jaws of five young adult mixed breed dogs were divided into two groups of control and experimental groups. Orthodontic force...
متن کاملEffect of canal length and curvature on working length alteration with WaveOne reciprocating files.
INTRODUCTION This study evaluated the working length (WL) modification after instrumentation with WaveOne Primary (Dentsply Maillefer, Ballaigues, Switzerland) reciprocating files and the incidence of overinstrumentation in relation to the initial WL. METHODS Thirty-two root canals of permanent teeth were used. The angles of curvature of the canals were calculated on digital radiographs. The ...
