Evaluation of the Cyclic Fatigue and Torsional Resistance of Novel Nickel-Titanium Rotary Files with Various Alloy Properties

Cyclic fatigue resistance of new reciprocating glide path files in 45‐ and 60‐degree curved canals

“…It has been also stated that the metal alloy of an endodontic file may affect its cyclic fatigue resistance (Kaval et al . , De‐Deus et al . ).…”

New thermomechanically treated NiTi alloys – a review

“…In accordance with these findings, several studies proved that Hyflex EDM exhibits a significantly increased cyclic fatigue resistance compared with Hyflex CM, M‐Wire and conventional NiTi instruments (Kaval et al . , Pedullà et al . , Pirani et al .…”

“…Only Hyflex EDM files have a significantly increased cyclic fatigue resistance compared with ProTaper Gold, WaveOne Gold and Reciproc Blue (Kaval et al . , Gündoğar & Özyürek ). All four Gold and Blue heat‐treated NiTi systems create well‐centred preparation even in severely curved root canals (Elnaghy & Elsaka , Silva et al .…”

Comparison of the Cyclic Fatigue Resistance of Nickel-Titanium Rotary Instruments Manufactured using Controlled Memory Wire

“…Similar to Pedulla et al [19] study, Kaval et al [20] compared the cyclic fatigue resistance of PTU, ProTaper Gold (Dentsply Maillefer), HyFlex EDM (Coltene/Whaledent) and HyFlex EDM showed statistically high cyclic fatigue resistance than the other files.…”
