Metodologia para determinar a relação dose-resposta de produtos fluoretados utilizando esmalte bovino e modelo de ciclagem de pH /

Vieira, Ana Elisa de Mello. January 2003 (has links)
Orientador: Alberto Carlos Botazzo Delbem / Resumo: O objetivo do presente trabalho foi desenvolver metodologia para determinar a relação dose-resposta de produtos fluoretados utilizando esmalte bovino e modelo de ciclagem de pH. Os blocos de esmalte, previamente selecionados através de microdureza de superfície, foram submetidos ao tratamento diário com solução placebo e soluções de NaF a 275, 550, e 1100 ppm F. Foram realizados dois métodos in vitro de desafio cariogênico para verificar o potencial dos produtos fluoretados para inibir a perda mineral (Des>Re) e a capacidade para promover a remineralização (Re>Des). Fatores de influência nas lesões in vitro produzidas no esmalte de dente bovino, como tempo de desmineralização e pH, tempo de remineralização, composição das soluções desmineralizadoras e remineralizadoras, freqüência e tempo de aplicação das soluções fluoretadas e duração da ciclagem foram O alterados para o estabelecimento de metodologia sensível, a partir dos modelos de Ten Cate & Duijsters (1982) e Featherstone et al. (1986). Após, realizou-se o cálculo da variação da microdureza de superfície, percentagem de volume mineral e flúor presente no esmalte. Testes paramétricos e não-paramétricos e análise de regressão foram utilizados para determinar relação dose-resposta entre os tratamentos realizados. As modificações propostas proporcionaram padronização das metodologias atingindo um alto nível de precisão, evidenciando relação dose-resposta entre os tratamentos em termos de flúor presente no esmalte, microdureza de superfície e percentagem de volume mineral em secção longitudinal. / Abstract: The aim of the present study was to establish methodology for verification of fluoride product dose-response relationship using a bovine enamel and pH-cycling model. Enamel blocks, previously selected in regards to surface microhardness, were submitted to daily treatment with placebo and NaF solutions (275, 550 and 1100 ppm F). Two in vitro methods of cariogenic challenge were performed to verify the potential of fluoride products to inhibit mineral loss and the ability to promote remineralization. Factors influencing in vitro bovine enamel lesions (time and pH of demineralization, time of remineralization, composition of demineralization and remineralization solutions, frequency and time of application of treatment solutions, and pHcycling duration) were altered for the establishment of a sensitive methodology, based on the studies of Ten Cate & Duijsters (1982) e Featherstone et al. (1986). Then, surface microhardness changes, % mineral volume and enamel's fluoride were calculated. Parametric and non-parametric tests and regression analysis were applied to establish dose-response relationship among different treatment groups. The proposed models provided for improvement in standardization of methods leading to a higher level of precision, demonstrating dose-response between treatments in regards to enamel's fluoride, surface microhardness and % mineral volume. / Mestre
