Resumo: | Objective: This study evaluated the effect of internal bleaching agents on the bond strength of glass fiber posts to root dentine.Methods: Seventy bovine teeth were divided into 7 experimental groups (n=10) according to the bleaching agent used: SpH – sodium perborate + 20% hydrogen peroxide; SpW – sodium perborate + distilled water; Cp37 – 37% carbamide peroxide; Cp16 – 16% carbamide peroxide; Cp10 – 10% carbamide peroxide; H – 35% hydrogen peroxide; C – no bleaching agent (control). After bleaching, posts were cemented with a self-adhesive resin cement (RelyX U100) and the roots were crosssectioned to obtain two discs from each third. The posts underwent micropush-out testing, and bond strength values (MPa) were analyzed using ANOVA in a split-plot arrangement and the Tukey test (p<0.05). Failure mode was evaluated under confocal microscopy.Results: There were no significant differences between the control and bleaching agent groups. Bond strength was greater in the cervical third of the 16% carbamide peroxide (Cp16) group than in the sodium perborate + 20% hydrogen peroxide (SpH) group. The cervical third had a higher bond strength than the apical third in the 10% carbamide peroxide (Cp10), 16% carbamide peroxide (Cp16) and sodium perborate + distilled water (SpW) groups, and no significant differences in the other groups. Adhesive cement-dentine failure was prevalent in all groups.Conclusion: The use of internal bleaching agents did not decrease the bond strength of glass fiber posts to root dentin. |

Após oclareamento, pinos foram cimentados com cimento resinoso auto-adesivo (RelyX U100) e as raízes foram seccionadas transversalmente para se obter dois discos de cada terço. As pinos foram submetidos a testes micropush-out, e os valores de resistência de união (MPa) foram analisados por ANOVAde duas vias, e o teste de Tukey (p<0,05). Falhas foram avaliada em microscopia confocal.Resultados: Não houve diferenças significativas entre os grupos de agentes de controle e de clareamento. A resistência de união foi maior no terço cervical do grupo de peróxido de carbamida 16% (CP16) do que no grupo perborato de sódio + peróxido de hidrogênio 20% (SPH). O terço cervical tinha uma força de ligação superior ao terço apical do peróxido de carbamida a 10% (CP10), 16% de peróxido de carbamida (CP16) e perborato de sódio + grupos água destilada (SPW), e não houve diferenças significativas nos outros grupos. Falhas adesivas de cimento-dentina foi prevalente em todos os grupos.Conclusão: O uso de agentes clareadores internos não diminuiu a resistência de união de pinos de fibra de vidro à dentina radicular.EDIPUCRS - Editora Universitária da PUCRS2016-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/2049010.15448/1980-6523.2016.3.20490Revista Odonto Ciência; Vol. 31 No. 3 (2016); 120-125Revista Odonto Ciência; v. 31 n. 3 (2016); 120-1251980-65230102-946010.15448/1980-6523.2016.3reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/20490/15585Copyright (c) 2017 Revista Odonto Ciência (Journal of Dental Science)info:eu-repo/semantics/openAccessFerreira, Josemar MartinsRenovato, Sara RodriguesSantana, Fernanda RibeiroDecurcio, Daniel de AlmeidaSoares, Carlos JoséEstrela, Carlos2017-05-09T21:52:00Zoai:ojs.revistaseletronicas.pucrs.br:article/20490Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2017-05-09T21:52Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false |
