The cyclic fatigue resistance for HyFlex EDM was 700% greater than that for HyFlex CM files made of the same alloy. The porous cratered surface of the EDM files was maintained with no change to the cutting blades even after being used in curved root canals [15]. Another study compared ...
Results: At 60掳, One Curve, F6 Skytaper and Hyflex CM had significantly longer fatigue lives than Protaper Next X2 (p < 0.05). No statistically significant differences were found in the cyclic fatigue lives of One Curve, F6 Skytaper, and Hyflex CM (p > 0.05). SEM images of the ...
Torsional preloading lowered the Nof EDM at 15% preloading (<.05) and the Nof CM at 50% preloading (<.05). However, the Nof EDM files even with 50% torsional preloading was significantly higher than unused CM files (<.05). Fatigue prestressing even at 75% had no negative effect on ...

However, the N-f of EDM files even with 50% torsional preloading was significantly higher than unused CM files (P<.05). Fatigue prestressing even at 75% had no negative effect on the torque and rotation angle of the EDM files. Moderate precycling (50%) of EDM files increased their ...
