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 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...

OBJECTIVE To evaluate the shaping ability of Reciproc and Twisted-File Adaptive systems in rapid prototyping replicas. MATERIAL AND METHODS Two mandibular molars showing S-shaped and 62-degree curvatures in the mesial root were scanned by using a microcomputed tomography (μCT) system. The data were exported in the stereolitograhic format and 20 samples of each molar were printed at 16 µm reso...

AIM To evaluate ex vivo, apical bacterial extrusion associated with two reciprocating single-file systems (WaveOne and Reciproc) compared with a conventional multifile rotary system (BioRace). METHODOLOGY Forty-five human single-rooted mandibular incisors were used. Endodontic access cavities were prepared, and root canals were contaminated with an Enterococcus faecalis suspension. Following ...

To evaluate the amount of apically extruded debris, percentage of foraminal enlargement and apical foramen (AF) deformation that occurred during root canal preparation with different reciprocation systems: Reciproc, WaveOne (M-Wire), and ProDesign R (Shape Memory Technology Wire) at two different working lengths (WLs): 0.0 and 1.0 mm beyond the AF. The AF of 120 root canals in 60 mesial roots o...

Amaç: Bu çalışmanın amacı, tek bir endodontist tarafından kullanılan Reciproc Blue R25 NiTi aletlerdeki kırık ve deformasyon tiplerini stereomikroskop taramalı elektron mikroskobu ile analiz etmektir.
 Gereç Yöntem: Çalışmada yaklaşık olarak 4 aylık dönemde endodonti kliniğinde 5 molar dişte kullanılmış imha edilmek üzere ayrılmış 47 adet alet kullanıldı. Ultrasonik temizlenip, otoklavlana...
