Material and Methods: Thirty sterile NiTi endodontic rotary files were randomly selected and assigned to one of the following study groups: A: 25.08 F2 Endogal (EDG) (n = 10); B: 25.08 F2 Path Max Pro (PMP) (n = 10); and C: 25.06 Smarttrack (ST) (n = 10). Dynamic cyclic fatigue tests were conducted using a cyclic fatigue device in stainless steel artificial root canal systems with an apical diameter of 250 µm, curvature angle of 60°, radius of curvature of 3 mm, and taper of 6%. Additionally, we analyzed the NiTi endodontic rotary files using EDX, SEM, and morphometry after micro-CT scanning. The results were analyzed using Weibull statistical analysis and ANOVA testing. Results: SEM, EDX, and morphometric analyses showed differences between the three novel brands of NiTi endodontic rotary files. Moreover, statistically significant differences were observed between the number of cycles to failure and time to failure of the three novel brands of NiTi endodontic rotary files (p < 0.001). Conclusions: Smarttrack NiTi alloy endodontic reciprocating files display greater resistance to cyclic fatigue than Endogal and Path Max Pro NiTi alloy endodontic rotary files, due to the reciprocating movement and metallurgical composition. 000120248 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000120248 592__ $$a0.828$$b2022 000120248 593__ $$aHealth, Toxicology and Mutagenesis$$c2022$$dQ2 000120248 593__ $$aPublic Health, Environmental and Occupational Health$$c2022$$dQ2 000120248 593__ $$aPollution$$c2022$$dQ2 000120248 594__ $$a5.4$$b2022 000120248 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000120248 700__ $$aPérez García, Raúl 000120248 700__ $$aFaus-Llácer, Vicente 000120248 700__ $$aFaus-Matoses, Ignacio 000120248 700__ $$0(orcid)0000-0003-3868-6784$$aAlonso Ezpeleta, Óscar$$uUniversidad de Zaragoza 000120248 700__ $$aAlbaladejo Martínez, Alberto 000120248 700__ $$aZubizarreta-Macho, Álvaro 000120248 7102_ $$11013$$2275$$aUniversidad de Zaragoza$$bDpto.
