Background. The aim of this study was to compare the dentinal defects caused by Reciproc, TF Adaptive and ProTaper Next NiTi rotary file systems during the retreatment procedure. Methods. A total of 150 mandibular incisors with straight and single root canals were included in the present study. All the root canals were prepared up to an apical diameter 0.40 mm using stainless steel files. Thirt...

AIMS The aim of this study is to evaluate increases in temperature on the external root surface during endodontic treatment with different rotary systems. MATERIALS AND METHODS Fifty human mandibular incisors with a single root canal were selected. All root canals were instrumented using a size 20 Hedstrom file, and the canals were irrigated with 5% sodium hypochlorite solution. The samples w...

The presence of debris, defects and deformations of endodontic reciprocating instruments before and after chemical-mechanical preparation (MCP) was analyzed using scanning electron microscopy (SEM). The following 26 instruments were divided into 2 groups: Waveone (n=13) and Reciproc (n=13) and examined by SEM (150 x magnification) prior to canal preparation at 2 and 4 mm from the tip. The instr...

Amaç: Endodonti alanında resiprokal hareket yapan tek eğe sistemleri son yıllarda popüler hâle gelmiştir. Apikalden taşan debrisin miktarı, kullanılan sistemlerinin tasarımlarına göre çeşitlilik gösterebilmektedir. Bu in vitro çalışmanın amacı, resiprokasyon hareketi ile çalışan Scope Reciproc, T-Endo MUST, EndoART Reciproc ve WaveOne Gold sistemlerinin, kök kanal preparasyonu sırasında apikald...

INTRODUCTION The aim of this study was to compare the formation of dentinal crack and craze lines in the root dentin during root canal preparation with three different NiTi endodontic systems, naming Reciproc (RCP), ProTaper Universal (PTU) and Mtwo. METHODS AND MATERIALS One hundred extracted mandibular premolars with single canals were selected and decoronated. The teeth were randomly divid...

Background. This study compared the cyclic fatigue resistance, bending resistance and cross-sectional areas of Reciproc Blue (RPC Blue), WaveOne Gold (WOG), and Genius File (GF) NiTi rotary systems. Methods. Forty RPC Blue R25 (25/.08), 40 WOG Primary (25/.07) and 40 GF (25/.04) files were used in the present study. Flexibility of the files was determined by 45° bending test. The instruments we...

BACKGROUND The aim of the present study was to compare clinically the incidence of postoperative pain after endodontic treatment using the Reciproc System, taking into account the operator's experience. MATERIAL AND METHODS One hundred patients scheduled for routine endodontic treatment were enrolled in this study. Endodontic treatment was carried out in a single visit by undergraduate and po...
