O tratamento t\u00e9rmico dos instrumentos ProFile (tamanho de ponta 25 e conicidade 0.06) foi realizado em um forno em atmosfera de arg\u00f4nio usando uma taxa de aquecimento de 10\u00b0C\/min. Ap\u00f3s atingir as temperaturas programadas de 450 \u00baC ou 500 \u00baC o sistema permaneceu em temperatura constante por 10 minutos; seguido de resfriamento em \u00e1gua \u00e0 temperatura ambiente. Em seguida; os tr\u00eas grupos de instrumentos (n=30 por grupo) foram comparados quanto \u00e0 fadiga c\u00edclica (n=10 por grupo); flex\u00e3o (n=10 por grupo) e resist\u00eancia \u00e0 flambagem (n=10 por grupo). Ap\u00f3s testes de fadiga c\u00edclica; um microsc\u00f3pio eletr\u00f4nico de varredura foi utilizado para analisar as superf\u00edcies de fratura e observar o modo de fratura. A an\u00e1lise estat\u00edstica foi realizada por meio dos testes de One-way ANOVA e teste de Student-Newman-Keuls; com erro de tipo alfa fixado em 0.05. Colora\u00e7\u00e3o amarelada e azulada foi observada nos instrumentos ProFile ap\u00f3s tratamentos t\u00e9rmicos a 450 \u00baC ou 500 \u00baC; respectivamente. Os instrumentos ProFile originais apresentaram menor fadiga c\u00edclica e maior resist\u00eancia \u00e0 flex\u00e3o e flambagem (P&lt;0.05). Em contraste; os instrumentos ProFile azulados (tratados termicamente a 500\u00b0C) apresentaram maior fadiga c\u00edclica e menor resist\u00eancia \u00e0 flex\u00e3o e flambagem (P&gt;0.05). Pode-se concluir que os diferentes tratamentos t\u00e9rmicos realizados nos instrumentos ProFile aumentaram sua resist\u00eancia \u00e0 fadiga c\u00edclica e melhoraram a flexibilidade e resist\u00eancia \u00e0 flambagem.<\/jats:p>","DOI":"10.1590\/0103-6440202204978","type":"journal-article","created":{"date-parts":[[2022,8,29]],"date-time":"2022-08-29T09:14:02Z","timestamp":1661764442000},"page":"47-53","source":"Crossref","is-referenced-by-count":2,"title":["Mechanical performance of original; yellowish and blueish ProFile instruments: isolating heat-treatment as a variable"],"prefix":"10.1590","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3793-542X","authenticated-orcid":false,"given":"Edson J.
