Cyclic Fatigue Resistance of 3 Different Nickel-Titanium Reciprocating Instruments in Artificial Canals

Laboratory comparison of cyclic fatigue resistance of WaveOne Gold, Reciproc and WaveOne files in canals with a double curvature

“…The manufacturers claim that the RECIPROC ALL mode has a speed of 300 rpm, and the WO ALL mode has a speed of 350 rpm (Higuera et al . ). Moreover, in double‐curved artificial canals, if the fracture occurred first in the apical curve, the time to fracture and NCF were also registered for the coronal fragment.…”

New thermomechanically treated NiTi alloys – a review

“…, Higuera et al . ). Concerning torsional fracture, the R‐phase instruments have a greater angle of deflection at failure but a decreased maximum torque compared with M‐Wire and conventional NiTi instruments (Casper et al .…”

Resistance to cyclic fatigue of PathFile, ScoutRaCe and ProGlider glide path files in an S‐shaped canal

“…The fracture of rotary files has been attributed to torsional failure and cyclic fatigue (Higuera et al . ). Cyclic fatigue is caused by compression and tensile stresses on a rotating file in a curved canal.…”
