Resumo: | Purpose: The aim of this in vitro study was to evaluate the fluoride concentration in mouthrinses and their capacity to intervene with the caries process. Methods: The analysis of the fluoride concentration in the solutions was carried with ion specific electrode connected to an ion analyzer. Bovine incisors enamel blocks with previously known superficial microhardness were submitted to a pH cycling model and treated with fluoridated solutions, and later reanalyzed for microhardness and fluoride incorporation. Results: The fluoride concentration (ppm) found in the solutions SANiFill- Sanikids®, Colgate Plax Fresh Mint®, Oral B®, Sorriso Fresh® and Cepacol® (not fluoridated) were, respectively: 242.91±21.89; 248.42±3.55; 248.29±11.31; 257.61±17.57 and 35.37±10.64. The lowest loss of superficial microhardness was observed with the use Sorriso Fresh® (29.66%± 8.84), followed by Plax Fresh mint® (32.99%±14.09) and Oral B® (43.00%±18.34). Conclusion: The data suggests that fluoride solutions, in proper concentrations, are capable of intervening on the phenomena of demineralization and remineralization, promoting fluoride incorporation and, consequently, decreasing the loss of microhardness on dental enamel. |

Metodologia: A análise da concentração de flúor nas soluções para bochecho foi realizada com eletrodo específico para íon flúor acoplado a um analisador de íons Orion. Blocos de esmalte de dentes incisivos bovinos com a microdureza superficial conhecida foram submetidos à ciclagem de pH e uso de soluções fluoretadas, sendo, posteriormente, avaliados por uma nova análise de microdureza e também pela incorporação de flúor. Resultados: As concentrações de flúor (ppm) encontradas nas soluções SANiFill®, Colgate® Plax®, Oral B®, Sorriso® e Cepacol® (não fluoretada) foram, respectivamente: 245,94; 247,61; 251,50; 258,01 e 38,44. A menor perda de porcentagem de dureza superficial foi observada com o uso da solução fluoretada Sorriso® (29,7%±14,4), seguida por Colgate® Plax® (33%±14,1) e Oral B® (43%±18,3). Todas as soluções fluoretadas analisadas mostraram capacidade de incorporar flúor no esmalte dental. Conclusão: Os dados sugerem que as soluções fluoretadas foram capazes de interferir nos fenômenos de desmineralização e remineralização, promover incorporação de flúor e, conseqüentemente, diminuir a perda de dureza no esmalte dental.EDIPUCRS - Editora Universitária da PUCRS2010-06-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/4443Revista Odonto Ciência; Vol. 25 No. 2 (2010); 194 - 197Revista Odonto Ciência; v. 25 n. 2 (2010); 194 - 1971980-65230102-9460reponame: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/4443/5343Carvalho, Maira de Souzade Oliveira, Juliana Maria SouzaPereira, Juliana ViannaRebelo, Maria Augusta Bessainfo:eu-repo/semantics/openAccess2013-11-11T12:39:32Zoai:ojs.revistaseletronicas.pucrs.br:article/4443Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-11-11T12:39:32Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false |
