The study included 40 NiTi instruments (25 mm) from four reciprocating systems groups: RB R25, WOG 25, OR 25, and RC-One 25. Instruments were inspected for defects. Bending tests assessed memory control. Static cyclic fatigue tests used an artificial 60\u00b0 curved canal with motorized activation. Torsional fatigue followed ISO 3630-1, measuring torque and angular deflection until failure. Fractured surfaces were analyzed using automated image analysis and measured with Rhinoceros 8.0 software. Statistical analysis included central tendency and dispersion measures, followed by ANOVA to identify statistically significant differences between groups.Results: The bending test showed RC-One retained shape after pressure, while RB exhibited moderate resistance. WOG and OR did not demonstrate satisfactory bending resistance. Analysis of cyclic fatigue revealed RC-One had the highest resistance, followed by RB, OR, and WOG (p<\/jats:p>","DOI":"10.14744\/eej.2024.08860","type":"journal-article","created":{"date-parts":[[2025,3,21]],"date-time":"2025-03-21T09:15:04Z","timestamp":1742548504000},"page":"159-172","source":"Crossref","is-referenced-by-count":3,"title":["Cyclic Fatigue, Torsional Strength and Angular Deflection of Different Reciprocating Instruments: A Critical Analysis of Its Clinical Relevance"],"prefix":"10.65717","volume":"10","author":[{"given":"Javier Caviedes","family":"Bucheli","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abel Teves","family":"Cordova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Murilo Priori","family":"Alcalde","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hugo Roberto","family":"Munoz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hernan Dario Mu\u00f1oz","family":"Alvear","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monique Marie","family":"Gay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo","family":"Portigliatti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose Francisco Gomez","family":"Sosa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge Olmos","family":"Fassi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco Antonio Hungaro","family":"Duarte","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"55248","published-online":{"date-parts":[[2025,3,14]]},"container-title":["European Endodontic Journal"],"original-title":[],"link":[{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/320\/320","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/320\/320","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T12:18:25Z","timestamp":1769084305000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/view\/320"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,3,14]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2025,3,14]]}},"URL":"https:\/\/doi.org\/10.14744\/eej.2024.08860","relation":{},"ISSN":["2548-0839"],"issn-type":[{"value":"2548-0839","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,3,14]]}}}
