Resumo: | The objective of this study was to determine the effect of biodegradation on the bond strength, surface characteristics and marginal integrity of restorative materials. For the bond strength assays, teeth were distributed into groups (n=5), according to the resin cement (Maxcem Elite (MC) or NX3 Nexus (NX)) and degradation method (24 h or 7 days in distilled water; 7 or 30 days incubated with S. mutans (UA159) and 30 days in sterile media). Treated surfaces of Vita Enamic (VE) blocks (5x6x7mm) were luted to treated (NX) or no treated (MC) dentin surfaces and light-cured. After 24 h, blocks were cut into beams (1x1x10mm) and stored accordingly. Biofilm viability was assessed after test by a luciferase assay. Then, the flexural bond strength FBS was assessed by a fourpoint bending test. Additional teeth were distributed into groups (n=3), according to the resin cement (MC and NX) and storage period (24h or 7 days in distilled water). Beams were obtained as described before, stored accordingly and submitted to a microtensile bond strength (µTBS) assay. Failure modes were determined by scanning electron microscopy (SEM) at 100X. Bars of cements (n=10) were obtained and their flexure strength assessed by a four-point bending test. Data were analyzed by 2-ways ANOVA and Tukey’s test (α=0.05). To assess the effect of biodegradation on surface characteristics, specimens (4 mm diameter x1.5 mm thick) were distributed in 12 groups (n = 15) according to the material (MC, NX, VE) and biodegradation method (24 h or 7 days in distilled water, 37ºC; 7 days in stimulated saliva or in situ). Before and after each degradation method, the surface roughness (Ra), Vickers hardness (VHN) and SEM analyzes were performed. For the marginal integrity evaluation, cavity preparations (5 mm diameter x 1.5 mm deep) were machined into dentin disks. After applying the bonding agent, preps (n=3-5) were restored by incremental technique with experimental resin composites (50:50 BisGMA/TEGDMA: 72wt% filler) containing different filler composition: (57wt% silanated strontium glass/15wt% BAG-65wt% silica) or (67wt% silanated strontium glass/5% OX50). Samples were stored in sterile Todd-Hewitt media or co-incubated with Streptococcus mutans (UA 159), at 37°C, 5%CO2 for 1-2 weeks. After, biofilm viability was assessed by a luciferase assay. Surfaces were replicated and examined in the SEM before and after the degradation method. Using an image software (Image J), gap width and percentage of discontinuous margins (%DM) was quantitatively assessed. Data were analyzed using two-way ANOVA followed by Tukey’s test (α= 0.05). Regarding the bond strength assays, there was no significant difference between the degradation methods for the FBS groups. For the µTBS, there was a significant difference among the groups as follows: NX 7days > NX 24h > MC 7days >MC 24h. Failure mode was mainly adhesive and mixed, but with an increase of cohesive within cement and pre-test failures for the MC groups assessed by µTBS. NX had better performance than MC, regardless the method. After surface characteristics analysis it could be observed that in situ aging method significantly altered the VHN of Vita Enamic and Maxcem Elite and the Ra of the Maxcem Elite. Surface changes analyzed by the SEM were more evident for the Saliva groups, of all materials. Regarding the marginal integrity of dentin-composite restoration, gap size ranged between 7-23µm. The bacterial exposure significantly increased the %DM in both groups predominantly due to the formation of new gap regions. There was no difference between control and BAG composites regarding %DM and the biofilm presence. Within the limitations of this study, it could be concluded that in situ and in vitro biodegradation can negatively affect the marginal integrity and superficial characteristics of restorative materials, having no further effect on the bond strength. |

Para os ensaios de resistência de união, dentes foram distribuídos em grupos (n=5) de acordo com o cimento resinoso (Maxcem Elite (MC) or NX3 Nexus (NX)) e o método de degradação (24 h ou 7 dias em água destilada; 7 ou 30 dias incubado com S.mutans (UA159) e 30 dias armazenado em metio estéril). Superfícies tratadas de blocos de Vita Enamic (VE) (5 x 6 x 7 mm) foram cimentadas a superfícies tratadas (NX) ou não (MC) de dentina e fotopolimerizadas. Após 24 h, os blocos foram cortados em palitos (1 x 1 x 10 mm) e armazenados de acordo. A viabilidade do biofilme foi avaliada após o teste por um ensaio de luciferase. Em seguida, a resistência de união flexural (FBS) foi avaliada por um teste de flexão de quatro pontos. Dentes adicionais foram distribuídos em grupos (n = 3), de acordo com o cimento resinoso (MC e NX) e período de armazenamento (24h ou 7 dias em água destilada). Os palitos foram obtidos como descrito anteriormente, armazenados em conformidade e submetidos a um ensaio de resistência de união à microtração (µTBS). Os modos de falha foram determinados por microscopia eletrônica de varredura (MEV) em 100X. Barras de cimentos (n = 10) foram obtidas e sua resistência à flexão avaliada por um teste de flexão de quatro pontos. Os dados foram analisados por ANOVA dois fatores e teste de Tukey (α = 0,05). Para avaliar o efeito da biodegradação nas características superficiais, espécimes (4 mm diâmetro x 1,5 mm espessura) foram distribuídos em 12 grupos (n = 15) de acordo com o material (MC, NX, VE) e método de biodegradação (24 h ou 7 dias em água destilada, 37ºC; 7 dias em saliva estimulada ou in situ). Antes e após cada método de degradação, foram realizadas as análises de rugosidade superficial (Ra), dureza Vickers (VHN) e MEV. Para a avaliação da integridade marginal, preparos cavitários (5 mm diâmetro x 1,5 mm profundidade) foram realizados em discos de dentina. Após a aplicação do sistema adesivo, as cavidades (n = 3-5) foram restauradas pela técnica incremental com resinas compostas experimentais (50:50 BisGMA / TEGDMA: 72% em peso) contendo diferentes composições de carga: (vidro de estrôncio silanizado a 57% por peso / 15% em peso de particula de vidro bioativa (BAG) BAG -65% em peso de silica) ou (67% em peso de vidro de estrôncio silanizado / 5% de OX50). As amostras foram armazenadas em meio Todd-Hewitt estéril de ou co-incubadas com Streptococcus mutans (UA 159), a 37 °C, 5% de CO2 durante 1 ou 2 semanas. Depois, a viabilidade do biofilme foi avaliada por um ensaio de luciferase. As superfícies foram replicadas e examinadas no MEV antes e depois do método de degradação. Usando um software de imagem (Imagem J), a largura do gap e a porcentagem discontinuidade marginal (% DM) foram avaliadas quantitativamente. Os dados foram analisados usando ANOVA dois fatores seguido pelo teste de Tukey (α = 0,05). Em relação aos ensaios de resistência de união, não houve diferença significativa entre os métodos de degradação dos grupos FBS. Para o µTBS, houve diferença significativa entre os grupos como segue: NX 7 dias> NX 24h> MC 7 dias> MC 24h. O modo de falha foi principalmente adesiva e mista, mas com um aumento de coesiva em cimento e falhas pré- teste para os grupos de MC avaliados pelo µTBS. O NX teve melhor desempenho que o MC, independentemente do método. Após análise das características da superfície, pôde-se observar que o método de envelhecimento in situ alterou significativamente a VHN de Vita Enamic e Maxcem Elite e a Ra da Maxcem Elite. As mudanças de superfície analisadas pelo MEV foram mais evidentes para os grupos Saliva, em todos os materiais. Em relação à integridade marginal da restauração da resina dentinária, o tamanho do gap variou entre 7-23µm. A exposição bacteriana aumentou significativamente a DM% de ambos os grupos, predominantemente devido à formação de novas regiões de gap. Não houve diferença entre os grupos controle e BAG em relação ao %DM e a presença de biofilme. Dentro das limitações deste estudo, podese concluir que a biodegradação in situ e in vitro pode afetar negativamente a integridade marginal e as características superficiais dos materiais restauradores, não tendo efeito sobre a resistência de união.porUniversidade PositivoPrograma de Pós-Graduação em Odontologia ClínicaUPBrasilPós-GraduaçãoCNPQ::CIENCIAS DA SAUDE::ODONTOLOGIAClinical dentistryBiofilmsDental bondingSurface propertiesDental materialsBiodegradation of restorative materials: effects on bond strength, surface characteristics and marginal integrityinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisNolasco, Gisele Maria Correrhttp://lattes.cnpq.br/6612641373865783Ferracane, Jack Libóriohttp://lattes.cnpq.br/9212511996580163Mushashe, Amanda Mahammadinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da Universidade Cruzeiro do Sulinstname:Universidade Cruzeiro do Sul (UNICSUL)instacron:UNICSULORIGINALAmanda Mushashe.pdfAmanda Mushashe.pdfTeseapplication/pdf16533462http://dev.siteworks.com.br:8080/jspui/bitstream/123456789/2158/1/Amanda%20Mushashe.pdfda8e198df0d307f329ae10f9fcb70d1dMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81748http://dev.siteworks.com.br:8080/jspui/bitstream/123456789/2158/2/license.txt8a4605be74aa9ea9d79846c1fba20a33MD52123456789/21582021-06-23 10:03:36.982oai:repositorio.cruzeirodosul.edu.br: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Repositório InstitucionalPRIhttps://repositorio.cruzeirodosul.edu.br/oai/requestmary.pela@unicid.edu.bropendoar:2021-06-23T13:03:36Repositório Institucional da Universidade Cruzeiro do Sul - Universidade Cruzeiro do Sul (UNICSUL)false |
