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 the torque and rotation angle of the EDM files. Moderate precycling (50%) of EDM files increased their torsional ...
The metallographic analysis of new and used files disclosed a homogeneous structure, mostly composed of lenticular martensite grains, and some residual austenite. The cyclic fatigue test showed an increase of fatigue resistance up to 700% on the EDM compared to CM files. Conclusions Spark-machined ...
Evaluation of Canal-centering Ability and Apical Transportation of Hyflex-EDM, OneShape, WaveOne Gold, and Reciproc Files: An Ex Vivo Study Aim: To evaluate and compare canal-centering ability (CCA), canal transportation (CT), and dentinal crack formation by using Hyflex-electrical discharge ma....

Torsional preloading lowered the N-f of EDM at 15% preloading (P<.05) and the N-f of CM at 50% preloading (P<.05). 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 ...
The aim of this study was to investigate the efficacy of using novel Reciproc Blue (RBlue) and HyFlex EDM (HEDM) files on postoperative pain after single visit root canal treatment. Materials and Methods: 72 patients with asymptomatic pulp necrosis in mandibular molar ...
Also, Hyflex-EDM was better in the apical third. Conclusion: No difference in CCA was observed between the groups. The lowest values for CT were obtained for WaveOne Gold (similar to Reciproc) whereas both rotary files showed higher values for CT. Also, ...
After access cavity preparation, the patients were randomly assigned to receive glide path enlargement with either HyFlex EDM GPF or PathFile. ProTaper Next X1 and X2 files were used to prepare the canals. The time of preparation was assessed and the severity of postoperative pain over the next...
