Two measurements at the instrument's tip were made with a digital calliper. Cyclic fatigue resistance was evaluated under single (60\u00b0, 5 mm radius) and double curvatures (60\u00b0, 5 mm radius each) in a 37\u00b0C water bath. Time to fracture (seconds) was recorded and analysed with appropriate statistical tests (p=0.05).Results: The tip sizes of all instruments were smaller than the value purported by the manufacturers (0.25 mm) and outside the range of values obtained, with significant differences for all groups (p<\/jats:p>","DOI":"10.14744\/eej.2025.85547","type":"journal-article","created":{"date-parts":[[2025,5,13]],"date-time":"2025-05-13T08:32:58Z","timestamp":1747125178000},"page":"237-241","source":"Crossref","is-referenced-by-count":5,"title":["Cyclic Fatigue Resistance of \u201cReplica-Like\" and Original Reciprocating Instruments in Single and Double Curvatures"],"prefix":"10.65717","volume":"10","author":[{"given":"Celia","family":"Tarrag\u00f3","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oliver Valencia De","family":"Pablo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaizka","family":"Loro\u00f1o","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Conde","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth Perez","family":"Alfayate","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giampiero Rossi","family":"Fedele","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge","family":"Vera","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Estevez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"55248","published-online":{"date-parts":[[2025,4,8]]},"container-title":["European Endodontic Journal"],"original-title":[],"link":[{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/331\/331","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/331\/331","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T12:17:25Z","timestamp":1769084245000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/view\/331"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4,8]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2025,4,8]]}},"URL":"https:\/\/doi.org\/10.14744\/eej.2025.85547","relation":{},"ISSN":["2548-0839"],"issn-type":[{"value":"2548-0839","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,4,8]]}}}
