Resumo: | This study assessed the bond strength of a resin cement when Immediate Sealed Dentin (ISD) was contaminated by different temporary cements applying a microshear test. Forty-eight fragments of third molar crowns were mounted in acrylic resin and worn until the dentin was exposed. The substrates were sealed with a 3-step conventional adhesive system and divided into four groups (n=12): Control (without temporary cement) and three groups that used different temporary cements - Provy, RelyX Temp NE, and Provitemp. The temporary cements were removed after 7 days of storage. Resin cement RelyX ARC was applied to the contaminated substrates. Microshear bond strength was evaluated using a universal testing machine (0.5 mm/min). Data was analyzed with ANOVA and a Dunnett post-hoc test (p<0.05). Additionally, three samples from each group were prepared for scanning electron microscope analysis. Means and standard deviations of microshear bond strength (MPa) were 17.96±1.65, 16.70±1.43, 20.43±1.30 and 33.75±4.72 for Control, Provy, RelyX Temp, and Provitemp, respectively. Statistically significant difference was observed between the Control and Provitemp samples (p=0.0002). Adhesive failures were dominant (50%), followed by cohesive failures with cement (26%), and cohesive failures with dentin (24%). Residues of Provy and Provitemp were observed on the sealed dentin. Provitemp temporary cement sealing increased the microshear bond strength of the resin cement on dentin treated with IDS. |

Quarenta e oito fragmentos obtidos das coroas de terceiros molares foram incluídos em tubos de PVC com resina acrílica e desgastados até exposição da dentina. Os substratos foram tratados com adesivo convencional de três passos e divididos em quatro grupos: Controle (sem cimento temporário) e três grupos usando diferentes cimentos temporários – Provy, RelyX Temp NE e Provitemp. Após sete dias, os cimentos foram removidos e o cimento RelyX ARC aplicado sobre o substrato contaminado. A resistência de união foi avaliada em uma máquina de ensaio universal (0,5 mm/min). Os dados foram analisados pelos testes estatísticos ANOVA e Dunnet (p<0,05). Três amostras de cada grupo foram preparadas para análise em micróscopio eletrônico de varredura. Os valores médios e desvio padrão da resistência de união foram 17,96 ±1,65, 16,70 ±1,43, 20,43±1,30 e 33,75 ±4,72 para Controle, Provy, RelyX Temp e Provitemp, respectivamente. Diferença significativa foi observada entre os grupos Controle e Provitemp (p=0,0002). Com relação ao padrão de fratura, a maioria das falhas foram adesivas (50%), seguida por coesiva em cimento (26%) e coesiva em dentina (24%). Resíduos dos cimentos Provy e Provitemp foram observados na dentina selada. Cimento temporário Provitemp aumentou a resistência de união por microcisalhamento do cimento resinoso a dentina com IDS.EDUFU2017-02-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3466810.14393/BJ-v33n1a2017-34668Bioscience Journal ; Vol. 33 No. 1 (2017): Jan./Feb.; 247-256Bioscience Journal ; v. 33 n. 1 (2017): Jan./Feb.; 247-2561981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/34668/19777Brazil; ContemporaryCopyright (c) 2017 Marcio Ferreira Lima, Carolina Menezes Marciel, Ayla Macyelle de Oliveira Correia, Sandro Griza, Adriano Augusto Melo de Mendonçahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLima, Marcio FerreiraMarciel, Carolina MenezesCorreia, Ayla Macyelle de OliveiraGriza, SandroMendonça, Adriano Augusto Melo de2022-02-16T16:34:44Zoai:ojs.www.seer.ufu.br:article/34668Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-16T16:34:44Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
