In the past 10 years, several proprietary processing procedures for nickel titanium (NiTi)
alloy were developed to improve the mechanical properties of NiTi endodontic instruments …

Ever since their introduction, nickel–titanium (NiTi) alloys have continued to revolutionize the
field of endodontics. They have considerable advantages over the conventional stainless …

Introduction The purpose of this study was to compare the cyclic fatigue resistances of
Reciproc Blue (VDW, Munich, Germany), HyFlex EDM (Coltene/Whaledent, Altstätten …

Introduction Recently, we reported that in mandibular molars contracted endodontic cavities
(CECs) improved fracture strength compared with traditional endodontic cavities (TECs) but …

Aim To evaluate the surface and microstructural alterations of new and used HyFlex EDM
prototypes and to test their fatigue resistance. Methodology Fifteen HyFlex EDM prototypes …

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 phase transformation behaviour, the microstructure, the nano‐hardness
and the surface chemistry of electro‐discharge machined HyFlex EDM instruments with …

Introduction This study compared the cyclic fatigue resistance of current nickel-titanium
rotary path-finding instruments. Methods Five types of nickel-titanium rotary pathfinding …

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 …

Aim To compare the shaping ability of three different nickel–titanium rotary instruments
during the preparation of curved root canals in extracted teeth. Methodology A total of 60 …
