Resumo: Objective: evaluate the effect of different luting protocols on the bond strength of glass fiber posts.Methods: Forty human canine teeth were randomly divided into four groups: Relyx U100/Endofill (R+E), Panavia F2.0/EndoFill (P+E), Relyx U100/Sealer 26 (R+S), Panavia F2.0/Sealer 26 (P+S). After the luting procedures, the samples were subjected to thermocycling (6.000 cycles; at 5±1 ºC and 55±1 ºC) and then sectioned in a precision cutting machine (Isomet 1000 Precision Saw) into 4 cuts of 2mm regarding to different deepness: Apical, Medium Apical, Medium Coronal, and Coronal. Next, the cuts were submitted to push-out test in a universal testing machine (EMIC) with load cell of 50N, at crosshead speed of 0.5mm/min.Results: They were obtained according to the different luting deepness (p≥0.05) (MPa): 1) apical – R+E (1.35±1.28), P+E (2.70±0.89), R+S (3.89±0.70), P+S (4.30±1.02); 2) medium apical – R+E (1.38±1.28), P+E (2.98±1.43), R+S (4.02±1.14), P+S (4.49±1.82); 3) medium coronal – R+E (2.46±0.73), P+E (3.72±0.78), R+S (4.85±0.71), P+S (6.14±0.73); 4) coronal R+E (5.59±1.08), P+E (5.74±1.06), R+S (6.71±1.07), P+S (7.40±1.51).Conclusion: There was a relationship between the luting protocol of the glass fiber post and the endodontic cement. Eugenol plays an important role inside the dentinal tubules by interfering negatively in the bond strength to root dentin.

R+E Relyx U100/ Endofill, P+E Panavia F2.0/EndoFill, R+S Relyx U100/Sealer 26, P+S Panavia F2.0/Sealer 26. Ao término dos procedimentos de cimentação, os corpos de prova foram seccionados em uma máquina de corte de precisão (Lab Cut Isomet 1000 Precision Saw) em 4 fatias de 2mm referente as diferentes profundidades: Apical, Médio Apical, Médio Coronal, Coronal. Em seguida, as fatias foram submetidas a ensaios mecânicos de extrusão Push-out em uma máquina de ensaios mecânicos EMIC com célula de carga de 50 N, a velocidade de 0,5 mm/min.Resultados: 1) Porção apical R+E (1,35±1,28), P+E (2,70±0,89), R+S (3,89±0,70), P+S (4,30±1,02); 2) porção médio apical R+E (1,38±1,28), P+E (2,98±1,43), R+S (4,02±1,14), P+S (4,49±1,82); 3) porção médio coronal R+E (2,46±0,73), P+E (3,72±0,78), R+S (4,85±0,71), P+S (6,14±0,73); 4) porção coronal R+E (5,59±1,08), P+E (5,74±1,06), R+S (6,71±1,07), P+S (7,40±1,51).Conclusão: Houve uma relação entre o protocolo de cimentação do pino de fibra de vidro e de cimento endodôntico. Eugenol desempenha um papel importante no interior dos túbulos dentinários, interferindo negativamente na resistência de união à dentina radicular.EDIPUCRS - Editora Universitária da PUCRS2016-12-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/2126310.15448/1980-6523.2016.2.21263Revista Odonto Ciência; Vol. 31 No. 2 (2016); 77-82Revista Odonto Ciência; v. 31 n. 2 (2016); 77-821980-65230102-946010.15448/1980-6523.2016.2reponame: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/21263/15143Copyright (c) 2016 Revista Odonto Ciência (Journal of Dental Science)info:eu-repo/semantics/openAccessde Landa, Fabiano VieiraMiranda, Jean Soaresde Carvalho, Rodrigo FurtadoKimpara, Estevão TomomitsuLeite, Fabíola Pessôa Pereira2016-12-26T15:46:23Zoai:ojs.revistaseletronicas.pucrs.br:article/21263Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2016-12-26T15:46:23Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
