Résumé

Changes in tooth color are a common esthetic problem in patients exposed to certain extrinsic or intrinsic factors. Among the extrinsic factors, the heavy metals deserve highlighting. Therefore, this study aimed to verify if there is association between the water consumed by residents from Caapiranga, Amazonas (Brazil) and changes in tooth color. This is a cross-sectional descriptive study. The calculated sample size (n = 350) was based on the prevalence of the phenomenon would be the maximum possible (50%) in a city not to exceed 100,000 people. Residents were examined by a dental surgeon from the Family Health Program staff in regular home visits. The clinical examination was carried out with a wood spatula under natural light. The water samples were collected in resistant plastic bottles. There were three collections in each well, with minimum volume of water (500 mL) to perform the analysis and then assess all metals of the study. There were 30 collections, since 10 wells were analyzed. The analyzed metals were: aluminum, antimony, arsenic, cadmium, lead, copper, cobalt, chromium, iron, magnesium, mercury, nickel, selenium, and zinc. Descriptive statistics were used and the measure of Odds Ratio (OR) for association checking. It was found that the only metal in excess was iron (0.4 to 4.3 mg/L) in water samples and 16.9% of staining in the teeth of residents of this sample (n = 332). There was an association between the staining and the presence of iron in the supply water (p = 0.015), presenting OR = 2.16(1.10 û 4.23). The quality of the water supply in some points of Caapiranga was in disagreement with the tolerable level for the presence of iron in water (0.33 mg Fe/L). As for the other metal the levels were within the limits of tolerance. It is suggested that teeth stain needs further studies because they can be an important indicator of the presence of iron and/or other metals in the water

Résumé

Introdução: Manaus não apresenta fluoretos na água de abastecimento público, mesmo sendo a oitava cidade mais populosa do Brasil. Objetivo: O objetivo neste trabalho foi conhecer as condições de saúde bucal de escolares aos 12 anos de idade, em relação à cárie dentária, nesse município de grande porte sem fluoretação da água de abastecimento público, no ano de 2003. Métodos: Os dados neste estudo foram obtidos do Projeto SB Brasil (MS) de 2003. Foi aplicada uma técnica de amostragem por conglomerados em três estágios que permitiu a produção de inferências para cada uma das macrorregiões brasileiras, por porte do município e para cada idade ou grupo etário. Foram examinadas 102 crianças de 12 anos das escolas públicas de Manaus. Resultados: O CPOD em Manaus (2003) foi 3,20. Conclusão: Portanto, atingir a meta para o ano de 2010 de CPOD menor que 1,0 está distante da real condição do Município de Manaus.


Introduction: Manaus has no fluoride in public water supply, even though is the eighth most populated city in Brazil. Objective: The aim in this paper was to know the oral health status of the 12-year-old scholars in relation to dental caries, in this large city without fluoridation of public water supply in the year 2003. Methods: The data of this study were obtained from the SB Brazil Project (MS) 2003. It was applied a technique of cluster sampling in three stages that allowed the production of inferences for each of the Brazilian regions, by size of municipality and for each age or age group. We examined 102 school children (12 years), from public schools in Manaus. The CPO-D in Manaus (2003) was 3.20. Conclusion: Therefore, the target for the year 2010 of a CPOD less than 1.0 is distant from the real condition of the city of Manaus.

Résumé

Objetivos: Determinar a prevalência da oclusão normal e da má oclusão em escolares de 7 a 11 anos, de ambos os gêneros, na rede estadual de ensino da cidade de Manaus, Amazonas; e estudar possíveis diferenças existentes entre os gêneros, obtendo assim, dados que possam servir de orientação a programas de saúdes dentárias. Métodos: Realizou-se levantamento das escolas públicas estaduais e o número de alunos que albergam. De cada zona administrativa de Manaus foi selecionada uma escola com oferecimento de educação até a 4ª série do ensino fundamental e com características semelhantes entre si em relação ao número de alunos. Foram examinados 957 escolares, independente de gênero e etnia, advindos de seis Escolas da Rede Estadual, com idade entre 7 a 11 anos. Resultados: Os dados obtidos mostraram que dos 957 escolares, 630 eram portadores de má oclusão, resultando numa prevalência de, aproximadamente, 66%, sendo que para portadores de oclusão normal, esta prevalência foi de 34%. Não houve diferença significativa entre os dois gêneros quanto à má oclusão. Conclusão: Fica evidente o elevado índice de má-oclusão na faixa etária estudada, o que denota a importância da adoção de medidas estratégicas de combate a esse problema. A criação de um programa de conscientização da população, e a realização de medidas interceptativas para a prevenção de oclusopatias, é sugerida para assegurar a superação deste problema de saúde pública.


Objectives: study occlusion conditions of the public school childrens (7 to 11 years) in Manaus, Amazonas, and determine possible gender differences. Methods: There were examined a total of 957 students, independently of gender or race, with ages ranging from 7 to 11 years old, from 6 schools. Results: The results have shown that 630 had malocclusion out of 957 students, resulting in a percentage of 66%. To normal occlusion students, this percentage was 34%. There was no significant difference between genders regarding to malocclusion, i.e., the malocclusion among boys (70%) was statistically similar to the percentage found in girls (63%). Approximately half of the students with permanent teeth have been classified as Class II, corresponding to 48% of the students with malocclusion. Conclusion: it is very clear the high malloclusion prevalence in this study, that showed the importance of the Health Departament to bring prevention and correction to the children´s oral problems.
