Time and number of cycles to fracture (NCF), as well as torque and angular deflection were recorded. Fractured surfaces were evaluated by scanning electron microscopy (SEM). Data were analysed using one\u2010way ANOVA and Holm\u2013Sidak's tests for multiple comparison. The RB had a significantly higher time to fracture, followed by the WOG and UCP (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Regarding the NCF, there was no significantly difference between RB and WOG (<jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05). UC presented highest torque values and the lowest angular deflection (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). SEM analysis demonstrated typical failures features in both cyclic and torsional fatigue tests. Overall, UC had the lowest time, NCF and angular deflection at fracture. RB presented the highest time to fracture and angular deflection values.<\/jats:p>","DOI":"10.1111\/aej.12774","type":"journal-article","created":{"date-parts":[[2023,7,13]],"date-time":"2023-07-13T10:40:02Z","timestamp":1689244802000},"page":"524-529","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Evaluation of cyclic and torsional fatigue resistance of several heat\u2010treated reciprocating nickel\u2013titanium instruments"],"prefix":"10.1111","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6810-1877","authenticated-orcid":false,"given":"Theodoro","family":"Weissheimer","sequence":"first","affiliation":[{"name":"Department of Conservative Dentistry Federal University of Rio Grande do Sul  Porto Alegre Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3051-737X","authenticated-orcid":false,"given":"Marco Antonio H\u00fangaro","family":"Duarte","sequence":"additional","affiliation":[{"name":"Department of Operative Dentistry, Endodontics and Dental Materials, Bauru School of Dentistry University of S\u00e3o Paulo  Bauru Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1393-5900","authenticated-orcid":false,"given":"Marcus Vinicius Reis","family":"S\u00f3","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry Federal University of Rio Grande do Sul  Porto Alegre Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6568-7403","authenticated-orcid":false,"given":"Ricardo Abreu","family":"da Rosa","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry Federal University of Rio Grande do Sul  Porto Alegre Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6429-7964","authenticated-orcid":false,"given":"Michel Klymus","family":"Espinosa","sequence":"additional","affiliation":[{"name":"Department of Operative Dentistry, Endodontics and Dental Materials, Bauru School of Dentistry University of S\u00e3o Paulo  Bauru Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0419-5699","authenticated-orcid":false,"given":"Rodrigo Ricci","family":"Vivan","sequence":"additional","affiliation":[{"name":"Department of Operative Dentistry, Endodontics and Dental Materials, Bauru School of Dentistry University of S\u00e3o Paulo  Bauru Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8735-065X","authenticated-orcid":false,"given":"Murilo Priori","family":"Alcalde","sequence":"additional","affiliation":[{"name":"Department of Operative Dentistry, Endodontics and Dental Materials, Bauru School of Dentistry University of S\u00e3o Paulo  Bauru Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,7,13]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.DON.0000129039.59003.9D"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2012.11.005"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/etp.12045"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10266-015-0214-5"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004770-200003000-00008"},{"key":"e_1_2_9_7_1","unstructured":"On\u2010line catalog of Unicone Plus (Medin Nov\u00e9 M\u011bsto na Morav\u011b Czech Republic).https:\/\/www.medin.cz\/unicone\u2010plus;
