Resumo: | Objective: This study evaluated the surface roughness of a nanofilled composite resin submitted to different degrees of erosion and methods of control.Methods: 120 cylindrical composite specimens (6×1.5 mm) were randomly divided into four groups, according to the surface protection against the erosive challenge [negative control, topical application of fluoride, glass-ionomer sealant, resin sealant]. After the application of the respective method, specimens were divided into three subgroups (n=10): a) absence of erosive challenge; b) 9 cycles of DES-RE; c) 18 cycles of DES-RE. Surface roughness (Ra, μm) was recorded and statistically analyzed (2-way Anova/Tukey).Results: The glass-ionomer sealant exhibited less rough surfaces under all the conditions. However, the average roughness was significantly higher after 18 DES-RE cycles.Conclusion: Despite the potential shown by glass-ionomer sealant, it was concluded that no material prevented an increase in surface roughness of the nanofilled composite after an intense erosive challenge. |

Após a aplicação dos respectivos métodos, os corpos de prova foram divididos em três subgrupos (n=10): a) ausência de exposição à solução simulada de ácido gástrico; b) 9 ciclos de DES-RE; c) 18 ciclos de DES-RE. Valores da rugosidade superficial (Ra, μm) foram registrados e analisados estatisticamente (Anova 2-critérios/Tukey).RESULTADOS: O selante ionomérico promoveu superfícies menos rugosas, em todas as condições experimentais testadas. Porém, todas as médias de rugosidade ficaram significativamente mais altas após 18 ciclos de DES-RE.CONCLUSÃO: Apesar do potencial demonstrado pelo selante ionomérico, conclui se que nenhum material foi capaz de evitar o aumento de rugosidade superficial da resina composta nanoparticuladas após a maior intensidade de desafio erosivo.EDIPUCRS - Editora Universitária da PUCRS2017-11-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/2793010.15448/1980-6523.2017.2.27930Revista Odonto Ciência; Vol. 32 No. 2 (2017); 88-93Revista Odonto Ciência; v. 32 n. 2 (2017); 88-931980-65230102-946010.15448/1980-6523.2017.2reponame: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/27930/16175Copyright (c) 2017 Revista Odonto Ciênciainfo:eu-repo/semantics/openAccessCavalcanti, Andrea NóbregaVaz de Queiroz, Mariana MenezesShibasaki, Patricia Akemi NishitaniLima, Max José PimentaFoxton, Richard Markde Araújo, Roberto Paulo Correia2018-04-04T16:33:37Zoai:ojs.revistaseletronicas.pucrs.br:article/27930Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2018-04-04T16:33:37Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false |
