CONTEXT One of the goals of endodontic therapy is the shaping and cleaning of the root canal system. In recent years, there has been multiple systems instrumentation, and changes in their dynamics are central to maintain the original shape of the canal after preparation. AIMS The aim of this study was to evaluate centering and transportation in curved root canals after using ProTaper(®) and M...

OBJECTIVE The purpose of this study was to evaluate the shaping ability of three nickel-titanium systems in simulated curved canals. MATERIALS AND METHODS Sixty simulated canals were prepared to apical size 25 with Reciproc, S5, and twisted file (TF) instruments. Standardized pre and postoperative images were taken using a digital camera, were superimposed and aberrations were recorded. Mater...

OBJECTIVES The study was to compare the shaping ability of Reciproc (VDW) and WaveOne (Dentsply Maillefer) instruments compared with ProTaper, Profile and hand instrument during the preparation of simulated root canals. MATERIALS AND METHODS Five groups (n = 5) were established. Reciproc, WaveOne, ProTaper, Profile and K file (K-flexo file) were used to prepare the resin simulated canals. A s...

The aim of this study was to quantitatively evaluate the amount of apically extruded debris by single-file reciprocating instruments with different working lengths and apical preparation sizes. Eighty human single-rooted mandibular incisors were used and conventional access cavities were prepared. Then, the specimens were divided into four groups (n=20), according to root canal instrumentation:...

The aim of the present study was to prospectively assess the frequency of teeth in which the Reciproc instruments were able to reach the full working length (WL). This case series study enrolled 277 consecutive teeth requiring primary endodontic treatment performed with the Reciproc system (VDW) without a previous glide path by 3 experienced endodontists. Instruments R25, R40 or R50 were select...

Aim: In vitro study evaluation of the cyclic fatigue resistance of reciprocating and rotary single-file system [Wave One Gold (WOG), Reciproc, Hyflex electrical discharge machining (EDM) file systems] utilizing cyclic fatigue testing device. Materials and methods: Three nickel–titanium rotary systems (Hyflex EDM size #25, 0.06 taper and Reciproc and WOG size #25, 0.06 taper) were used in this s...

Background and Aim: Pulpectomy of primary teeth is commonly performed with hand files and instruments. However, it is a time consuming procedure. Compared to hand files, rotary instrumentation has more advantages. The purpose of this in vitro study was to compare the cleaning efficacy and time taken for instrumentation of deciduous mo-lars using Reciproc and Mtwo rotary systems. Materials an...

BACKGROUND This study sought to compare the root canal debridement ability of Neolix, Reciproc and ProTaper rotary systems in long oval-shaped root canals. MATERIAL AND METHODS Eighty five extracted single-rooted human teeth with long oval-shaped single root canals were selected and divided into three experimental groups(n=25) and one control group (n= 10). Root canals were filled with Vitape...
