Cyclic fatigue resistance of ProTaper Universal, Twisted File Adaptive, Reciproc and WaveOne systems

Cyclic fatigue resistance of ProTaper Universal, Twisted File Adaptive, Reciproc and WaveOne systems

Cyclic fatigue of Reciproc and WaveOne reciprocating instruments.

AIM To evaluate the cyclic fatigue resistance of Reciproc(®) and WaveOne(®) instruments in simulated root canals. METHODOLOGY Two groups of 15 NiTi endodontic instruments of identical tip size of 0.25 mm were tested, group A; Reciproc(®) R25 and group B: WaveOne(®) primary. Cyclic fatigue testing was performed in a stainless steel artificial canal manufactured by reproducing the instrument's ...

Dentinal crack formation during root canal preparations by the twisted file adaptive, Reciproc and WaveOne instruments

OBJECTIVE This study aimed to compare the frequency of dentinal microcracks after root canal shaping with 2 reciprocating (Reciproc and WaveOne) and 1 combined continuous reciprocating motion twisted files adaptive (TFA) rotary system. MATERIALS AND METHODS Ninety molars were chosen and divided into three groups of 30 each. Root canal preparation was achieved by using Reciproc R25, Primary Wa...

Differences in cyclic fatigue resistance at apical and coronal levels of Reciproc and WaveOne new files.

INTRODUCTION Recent improvements in alloys, kinematics, and concepts have been combined to increase the cyclic fatigue resistance of nickel-titanium (NiTi) instruments. The aim of this study was to compare the cyclic fatigue resistance of new M-Wire reciprocating WaveOne (Dentsply Maillefer, Ballaigues, Switzerland) and Reciproc (VDW GmbH, Munich, Germany) files at 2 levels. METHODS Sixty Rec...

Efficiency of the Self Adjusting File, WaveOne, Reciproc, ProTaper and hand files in root canal debridement

OBJECTIVES The aim of this study was to compare the canal debridement capabilities of three single file systems, ProTaper, and K-files in oval-shaped canals. MATERIALS AND METHODS Seventy-five extracted human mandibular central incisors with oval-shaped root canals were selected. A radiopaque contrast medium (Metapex; Meta Biomed Co. Ltd., Chungcheongbuk-do, Korea) was introduced into the can...
