Resumo: | Dental cements must present satisfactory mechanical properties in order to support masticatory forces and occlusal loads in the oral cavity. The punch shear strength is a simple and efficient method to evaluate the strength of a material, by means of an axial load applied to dislocate one or several materials. Thus, the objective of this work was to evaluate three dental cements (a zinc phosphate, a glass-ionomer, and a resin cement) as to their punch shear strength. For this test, specimens in a ring form matrix with dimensions of 14mm of internal diameter and 1.5mm of height were made, allowing for a disc of the materials with these dimensions to be obtained, which was placed in an adequate testing device. Ten specimens of each material were analyzed for the respective test at periods of 1 and 24 hours. The results were statistically evaluated with the two-way ANOVA test, followed by the comparative Tukey’s test (5%). The dental cement which obtained the highest values of punch shear strength was the resin cement, whereas the glass-ionomer cement obtained the lowest values among all the analyzed materials in both periods. |

Dessa forma, o objetivo deste trabalho foi avaliar três agentes cimentantes (fosfato de zinco, ionômero de vidro e cimento resinoso), em relação às resistências ao cisalhamento por puncionamento. Para o ensaio, foram confeccionados espécimes em uma matriz em forma de anel com dimensões de 14 mm de diâmetro interno e 1,5 mm de altura, que permitia obter um corpo de prova em formato de disco. Um conjunto matriz-cimento foi posicionado num dispositivo próprio para o teste. Dez espécimes de cada material foram avaliados em dois períodos de uma hora e 24 horas. Os resultados foram tratados estatisticamente com Análise de Variância a dois critérios (ANOVA), seguida do teste comparativo de Tukey, em nível de significância de 5%. Dentre os agentes cimentantes avaliados nos dois períodos, o cimento resinoso apresentou os maiores valores de resistência ao puncionamento, e o cimento de ionômetro de vidro, os menores.Universidade Metodista de PiracicabaFreitas, Márcia Furtado Antunes deSilva, Breno Mont´alverne HaddadeFreitas, César Antunes deMondelli, José2011-02-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.metodista.br/revistas/revistas-unimep/index.php/Fol/article/view/5510.15600/2238-1236/fol.v21n1p7-14Revista da Faculdade de Odontologia de Lins; v. 21, n. 1 (2009): Revista da Faculdade de Odontologia de Lins; 7-142238-123601047582reponame:Revista da Faculdade de Odontologia de Lins (Online)instname:Universidade Metodista de Piracicaba (UNIMEP)instacron:UNIMEPporhttps://www.metodista.br/revistas/revistas-unimep/index.php/Fol/article/view/55/20info:eu-repo/semantics/openAccess2016-06-01T13:28:23Zoai:ojs-unimep.metodista.br:article/55Revistahttps://www.metodista.br/revistas/revistas-unimep/index.php/Folhttps://www.metodista.br/revistas/revistas-unimep/index.php/Fol/oai||revistafol@unimep.br|| nalfieri@unimep.br2238-12360104-7582opendoar:2016-06-01T13:28:23Revista da Faculdade de Odontologia de Lins (Online) - Universidade Metodista de Piracicaba (UNIMEP)false |
