Quality of life related to oral health: contribution from social factors

Lesions infiltrated with Icon(®) underwent greater color change when compared with remineralized lesions, which may represent an esthetic disadvantage for the first-mentioned treatment.

The objectives of this study were: (1) test the psychometric properties of OHIP-14 in a rural population; and (2) compare the oral health impacts in two riverine communities in the Brazilian Amazon that were living at different distances from an urban center. Data were obtained from a cross-sectional study in a consecutive sample (n = 126). The validity was assessed through the association of OHIP with clinical and subjective variables, which showed a more significant association with: pain, caries, need of extraction or endodontic treatment; than with tooth loss, periodontal disease or need of prostheses. The stability and internal consistency were good (ICC = 0.97; Cronbach's α = 0.89). The prevalence of oral impacts was greater in the community far from the urban center [70.3 (59.9-80.7)] than in the community closer to it [44.3 (30.7-57.7)], and in women [66.7 (56.0-77.3)] in comparison with men [49.1 (35.3-62.7)]. The OHIP-14 adapted to rural populations in Amazonas State was valid, reproducible, and consistent. There was high prevalence of impacts, especially for riverine communities that lived far from urban centers.

O presente estudo de caso teve o objetivo de descrever a oferta e utilização de serviços odontológicos em duas comunidades ribeirinhas do Município de Coari, Amazonas, Brasil. Para tanto, foram colhidos dados sobre freqüência de utilização de serviços de saúde bucal, por entrevistas estruturadas com indivíduos acima de 18 anos, e dados sobre oferta de serviços obtidos por entrevistas semi-estruturadas com informantes-chave. Nas análises bivariadas, embora sem diferença estatística, os indivíduos da comunidade mais distante da sede do município apresentaram maior tempo decorrido da última consulta, e menor proporção de atendimentos pelo serviço público e por barcos de saúde. A análise qualitativa das entrevistas revelou: ausência de serviço odontológico permanente nas comunidades; oferta esporádica através de barcos da saúde, com menor ocorrência dos serviços na comunidade mais distante; alto custo do deslocamento do ribeirinho à sede do município; e tratamento odontológico voltado para o controle da dor, basicamente se resumindo à extração dentária. O acesso precário dos ribeirinhos aos serviços de saúde bucal aponta para a necessidade de implantação de medidas amplas de promoção de saúde, aliada a maior oferta de serviços.

ObjectivesThe aim of this study was to evaluate the fluoride release of conventional glass ionomer cements (GICs) and resin-modified GICs.Materials and MethodsThe cements were grouped as follows: G1 (Vidrion R, SS White), G2 (Vitro Fil, DFL), G3 (Vitro Molar, DFL), G4 (Bioglass R, Biodinâmica), and G5 (Ketac Fil, 3M ESPE), as conventional GICs, and G6 (Vitremer, 3M ESPE), G7 (Vitro Fil LC, DFL), and G8 (Resiglass, Biodinâmica) as resin-modified GICs. Six specimens (8.60 mm in diameter; 1.65 mm in thickness) of each material were prepared using a stainless steel mold. The specimens were immersed in a demineralizing solution (pH 4.3) for 6 hr and a remineralizing solution (pH 7.0) for 18 hr a day. The fluoride ions were measured for 15 days. Analysis of variance (ANOVA) and Tukey's test with 5% significance were applied.ResultsThe highest amounts of fluoride release were found during the first 24 hr for all cements, decreasing abruptly on day 2, and reaching gradually decreasing levels on day 7. Based on these results, the decreasing scale of fluoride release was as follows: G2 > G3 > G8 = G4 = G7 > G6 = G1 > G5 (p < 0.05).ConclusionsThere were wide variations among the materials in terms of the cumulative amount of fluoride ion released, and the amount of fluoride release could not be attributed to the category of cement, that is, conventional GICs or resin-modified GICs.
