Resumo: | The composition of dental adhesives may influence their performance when used for adhesion to dental structures or ceramics. The purpose of the present study was to evaluate influence of different MDP concentrations on the shear bond strength of a resin cement to zirconia. Six experimental adhesives were prepared with the following composition: 0.50 % CQ by wt, 1.0 % DABE by wt, 0.20% BHT by wt, 0.45% DPHIF by wt, 10% HEMA by wt, 15% TEGDMA by wt, 25% BIS-EMA by wt, 10% ethanol by wt, 25% UDMA by wt, and 12.85% BIS-GMA by wt . The MDP monomer was added at 0% by wt, 3% by wt, 6% by wt, 9% by wt, 12% by wt, or 15% by wt. As a control, four commercially available adhesives were evaluated: Single Bond Universal, Single Bond 2, Ambar and Signum Zirconia Bond. The shear bond strength to zirconia was evaluated in a universal testing machine. Failure modes were analyzed with a stereoscopic loupe. Statistical analyses were performed with one-way Anova and Tukeys HSD test ( = 0.05). There were significant differences between groups (p < 0.00001). The highest shear bond strength values were obtained with Signum Zirconia Bond and Single Bond Universal. Singlebond 2 showed the lowest values. There were no differences between experimental adhesives. All groups showed adhesive failures. MDP-containing adhesives are important for bonding resin cements to zirconia, however, the concentration of MDP is not the only factor to be considered. |

O objetivo do presente foi avaliar a influência de diferentes concentrações de MDP na resistência ao cisalhamento de um cimento resinoso à zircônia. Seis adesivos experimentais foram preparados com a seguinte composição: 0,50% em peso de CQ, 1,0% em peso de DABE, 0,20% em peso de BHT, 0,45% em peso de DPHIF, 10% em peso de HEMA, 15% em peso de TEGDMA, 25% em peso de Bis-EMA, 10% em peso de etanol, 25% em peso de UDMA, e 12,85% em peso de BIS-GMA. O monômero MDP foi adicionado em seis porcentagens em peso: 0%, 3%, 6%, 9%, 12%, ou 15%. Como grupo controle, quatro adesivos disponíveis comercialmente foram avaliados: Single Bond Universal, Single Bond 2, Ambar e Signum Zirconia Bond. A resistência de união à zircônia foi avaliada em uma máquina de universal de ensaios através de teste de cisalhamento. Os modos de falha foram analisados com lupa estereoscópica. A análise estatística foi realizada com Anova a um critério e Tukey ( = 0,05). Foram encontradas diferenças significativas entre os grupos (p < 0,00001). Os valores de resistência ao cisalhamento mais elevados foram obtidas com o Signum Zirconia Bond e o Single Bond Universal. O adesivo sem MDP Single Bond 2 apresentou os valores mais baixos. Não houve diferenças entre os adesivos experimentais. Todos os grupos mostraram falhas adesivas. Concluiu-se adesivos que contenham MDP são importantes para a união à zircônia, entretanto, a concentração de MDP não é o único fator a ser considerado.Biblioteca Digitais de Teses e Dissertações da USPFuruse, Adilson YoshioLlerena Icochea, Alfredo Esteban 2016-04-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttps://www.teses.usp.br/teses/disponiveis/25/25148/tde-09112021-151253/reponame:Biblioteca Digital de Teses e Dissertações da USPinstname:Universidade de São Paulo (USP)instacron:USPLiberar o conteúdo para acesso público.info:eu-repo/semantics/openAccesseng2023-11-09T13:00:19Zoai:teses.usp.br:tde-09112021-151253Biblioteca Digital de Teses e Dissertaçõeshttp://www.teses.usp.br/PUBhttp://www.teses.usp.br/cgi-bin/mtd2br.plvirginia@if.usp.br|| atendimento@aguia.usp.br||virginia@if.usp.bropendoar:27212023-11-09T13:00:19Biblioteca Digital de Teses e Dissertações da USP - Universidade de São Paulo (USP)false |
