introduction: the exact measurement of the root canal length is of great importance in root canal therapy. although, determination of the root canal length through radiography is the most common method, recently electronic apex locators are being used to determine working length and decrease the number of radiographs. the purpose of this study was to compare the accuracy of an electronic apex l...
Comparison of the maintenance of root canal anatomy in severely curved resin blocks using RaCe and Flexmaster rotary systems Dr. S. Khedmat* - Dr. M. Vahdatifar** *- Associate Professor of Endodontics Dept. - Faculty of Dentistry – Tehran University of Medical Sciences. **- Endodontist. Background and Aim: Various rotary systems are available on the market, therefore selection of a proper instr...
Background and Aims: Estimating the canal length is essential for reaching to a proper endodontic treatment. Any error and miscalculation in estimation of the working length, especially in curved canals, can result in complication during and after root canal therapy. The introduction of digital radiography has enabled us to measure curved canal length. The purpose of this study was to evaluat...

Background and Objective: The preparation of the root canal (i.e., cleaning and shaping) is the main step in the endodontic treatment. The nickel-titanium rotary files result in fewer errors during the preparation of curved canals. This study aimed to compare the transportation of Neolix and Reciproc rotary systems in curved canals using cone beam computed tomography (CBCT). Materials and Meth...
Background and Aim: Recent advances in technology have permitted manufacturers to produce endodontic files from NiTi alloy and rotary systems. According to manufacturers, these files maintain original canal shape better than hand files and reduce treatment time. The aim of this study was to compare a new rotary system (Race) with an older one (Profile) in maintaining the original shape of curve...
OBJECTIVES The purpose of this study was to assess the ability of ProTaper Gold (PTG, Dentsply Maillefer) in maintaining the original profile of root canal anatomy. For that, ProTaper Universal (PTU, Dentsply Maillefer) was used as reference techniques for comparison. MATERIALS AND METHODS Twenty simulated curved canals manufactured in clear resin blocks were randomly assigned to 2 groups (n ...
Introduction: Successful treatment of root depends on complete elimination of debris and bacteria’s from root canal system and appropriate shaping of canal in obturation canal preparation is the most difficult and time consuming stage during root canal treatment. This stage especially in curved and narrow canals always causes some problems for students, general dentist and specialist. Following...
