Resumo: | Purpose: To evaluate the efficacy of smear layer removal by cavity cleaning agents by the use of atomic force microscopy (AFM). Methods: Five intact human third molars were sectioned in the coronal portion to obtain dentin disks, which were ground with 600-grit abrasive paper for 10 s. Serial longitudinal sections were made perpendicular to each other to create four specimens, from each tooth. The specimens were divided into four treatment groups: GI, 2% chlorhexidine; GII, calcium hydroxide solution; GIII, 1.23% fluoride solution; and GIV, 37% phosphoric acid. The solutions were applied with a brush for 60 s, with the exception of the 37% phosphoric acid, which was applied for 15 s and rinsed with distilled water for 60 s. The specimens were examined by AFM. Results: All of the specimens in GI and GII showed 100% of the dentin tubules obliterated by the smear layer. However, all of the specimens in GIII and GIV showed 0% of the dentin tubules obliterated by the smear layer. Conclusion: The 1.23% fluoride solution was effective in removing the smear layer and can be used as a cavity cleanser. |

Metodologia: Cinco terceiros molares humanos hígidos foram seccionados transversalmente na porção coronária, obtendo discos de dentina de 2 mm, que foram desgastados com lixas de granulação 600, por 10 s.Foram feitos cortes seriados longitudinais e perpendiculares entre si, obtendo-se quarto espécimes de cada dente. Os espécimes foram divididos em 4 grupos: GI- clorexidina 2%; GII- água de hidróxido de cálcio; GIII- solução fluoretada a 1,23%; GIV - ácido fosfórico 37%. As soluções foram aplicadas com pincel por 60 s, com exceção do ácido fosfórico que foi aplicado por 15 s e lavado com água destilada pelo mesmo tempo. Os espécimes foram analisados por MFA. Resultados: Todos os espécimes de GI e GII apresentaram 100 % dos túbulos dentinários obliterados por lama dentinária. Os espécimes de GIII e GIV apresentaram 0 % dos túbulos obliterados por lama dentinária. Conclusão: A solução de fluoretada a 1,23 % foi eficiente na remoção de lama dentinária, podendo ser empregada na limpeza de cavidades.EDIPUCRS - Editora Universitária da PUCRS2011-09-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/9536Revista Odonto Ciência; Vol. 26 No. 3 (2011); 253 - 257Revista Odonto Ciência; v. 26 n. 3 (2011); 253 - 2571980-65230102-9460reponame: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/9536/6888Neri, Jiovanne RabeloPassos, Vanara FlorêncioViana, Felipe Bandeira de AlencarRodrigues, Lidiany Karla AzevedoSaboia, Vicente de Paulo AragãoSantiago, Sérgio Limainfo:eu-repo/semantics/openAccess2013-11-11T11:52:28Zoai:ojs.revistaseletronicas.pucrs.br:article/9536Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-11-11T11:52:28Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false |
