Resumo: | Objective: this study aimed to verify whether the K type endodontic instruments of Angelus (Brazil), CC Cord VDW (Germany), and Dentsply-Maillefer (Switzerland) meet the tolerance level established by ANSI/ADA Standard 101 and to compare the cyclic fatigue resistance of instruments from different brands. Material and Methods: ten first series instruments of each tested brands were used. The images of the instruments were obtained with a stereoscopic magnifying glass attached to a digital camera. The measurements were performed using the TSView imaging software. The diameters of the instruments were determined from D0 to D12, with measuring intervals of 1.0 mm. The taper was calculated by adopting the diameters of D10 and D2. The cyclic fatigue test was performed using a custom device. The artificial canal was manufactured in a tapered manner corresponding to the instruments tested. Results: no trademark fully complies with ANSI/ADA Standard 101. The instruments presented different aspects of the finishing surface. The Dentsply-Maillefer instruments had greater cyclic fatigue strength than Angelus and CC Cord instruments (P < 0.05). The fracture surface morphologies of the instruments presented different characteristics. The Angelus instruments presented “sand marks” characteristics of failure of a material with high ductility. The Dentsply-Maillefer instrument presented a regular appearance, whereas the CC Cord presented irregular appearance. Conclusion: none of the brands fully complied with ANSI/ADA Standard 101. Dentsply-Maillefer brand instruments presented better cyclic fatigue results when compared to the other instruments tested. |

Material e métodos: Foram utilizados 10 instrumentos de cada uma das marcas testadas nos tamanhos #15, #20, #25, #30, #35 e #40. As imagens dos instrumentos foram obtidas com uma lupa estereoscópica acoplada a uma câmera digital. As medidas foram realizadas a partir do software de imagem TSView. Os diâmetros dos instrumentos foram determinados em D0 até D12 com intervalos de medidas de 1,0 mm. A conicidade foi calculada adotando os diâmetros D10 e D2 para o cálculo. O ensaio de fadiga cíclica foi realizado utilizando um dispositivo customizado. O canal artificial foi fabricado de forma afunilada de forma correspondente à dos instrumentos testados. Resultados: Nenhuma marca comercial atendeu plenamente a norma 101 da ANSI/ADA. Os instrumentos da marca Dentsply-Maillefer tiveram resistência à fadiga cíclica superior aos instrumentos Angelus e CC Cord (PAssociação Brasileira de Odontologia - Seção Rio de JaneiroDias, Douglas SouzaRibeiro, Guilherme DiasMartuche, Ranna da SilvaAntunes, Henrique dos SantosVieira, Victor Talarico LealSilva, Emmanuel João Nogueira Leal da2017-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionOriginal articleArtigo Originalapplication/pdfhttps://revista.aborj.org.br/index.php/rbo/article/view/86410.18363/rbo.v74n2.p.96Revista Brasileira de Odontologia; v. 74, n. 2 (2017); 96Revista Brasileira de Odontologia; v. 74, n. 2 (2017); 961984-3747reponame:Revista Brasileira de Odontologiainstname:Associação Brasileira de Odontologia (ABO)instacron:ABOporhttps://revista.aborj.org.br/index.php/rbo/article/view/864/612Direitos autorais 2017 Revistashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2017-06-29T11:59:36Zoai:revista_aborj_org_br.www.revista.aborj.org.br:article/864Revistahttps://revista.aborj.org.br/index.php/rboONGhttp://www.revista.aborj.org.br/index.php/rbo/oaihttps://revista.aborj.org.br/index.php/rbo/oai0034-72721984-3747opendoar:2017-06-29T11:59:36Revista Brasileira de Odontologia - Associação Brasileira de Odontologia (ABO)false |
