Root canal curvature and calcification introduce factors that increase the risk of procedural
accidents during root canal treatment. The inability to achieve patency to the apical third …

Differences in mechanical properties between endodontic instruments might be related to
the chemical composition, phase constitution, or fabrication process of nickel–titanium (NiTi) …

Introduction The aim of the present study was to evaluate the difference in cyclic fatigue
resistance between Vortex Blue (Dentsply Tulsa Dental, Tulsa, OK) and Profile Vortex nickel …

Aim To compare the resistance to cyclic fatigue of WaveOne Gold (WOG), Reciproc and
WaveOne (WO) nickel–titanium files in an artificial root canal with a double (S‐shaped) …

Background The purpose of this study was to compare the cyclic fatigue resistance of newly
developed TruNatomy instruments (TRN) in single and double (S-shaped) curvature canals …

Aims. Apical extrusion of infected debris to the periradicular tissues is one of the principal
causes of postoperative pain and discomfort. Recent researches have shown that …

Highlights•Environmental temperature may drastically affect the cyclic fatigue resistance of
nickel-titanium files.•Reciproc Blue instruments were statistically more resistant to cyclic …

Background Aim of this study is to investigate the cyclic fatigue resistance of the Gold treated
WaveOne Gold and the Firewire treated EdgeOne Fire instruments. The null hypotesis was …
