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 ...

OBJECTIVES The purpose of this study was to compare the maximum screw-in forces generated during the movement of various Nickel-Titanium (NiTi) file systems. MATERIALS AND METHODS Forty simulated canals in resin blocks were randomly divided into 4 groups for the following instruments: Mtwo size 25/0.07 (MTW, VDW GmbH), Reciproc R25 (RPR, VDW GmbH), ProTaper Universal F2 (PTU, Dentsply Maillef...

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...

introduction: one of the most important reasons for postoperative pain is the extrusion of debris from the apical foramen during preparation and shaping of root canals. the aim of this clinical trial was to evaluate the severity of postoperative pain with the use of two different engine-driven niti systems. methods and materials: ninety mandibular molars were randomly divided into two groups ( ...

introduction: in this experimental study, the amount of smear layer (sl) remnants in curved root canals after chemomechanical instrumentation with two engine-driven systems or hand instrumentation was evaluated. methods and materials: forty-eight mesiobuccal roots of mandibular first molars with curvatures ranging between 25 and 35 degrees (according to schneider’s method) were divided into thr...

OBJECTIVES The aim of this randomized, controlled, prospective clinical study was to evaluate patients' intraoperative discomfort during root canal preparations in which either multi-file rotary (Mtwo) or single-file reciprocating (Reciproc) systems were used. MATERIALS AND METHODS Fifty-five adult patients, aged between 25 and 69 years old, with irreversible pulpitis or pulp necrosis partici...
