Abstract

To analyze the oral health of 12 year-old students in the municipality of Nova Mutum-MT through the prevalence of caries, periodontal condition and fluorosis. Method: Transversal study with 538 12 year-old students from public and private schools of Nova Mutum/MT. For this epidemiological survey, clinical examination and socioeconomic questionnaire were conducted, both based on national survey of oral health – SB 2010 Brazil. Through clinical examination, data were collected on dental caries (decayed, missing and filled teeth index, DMFT), dental fluorosis (Dean index) and periodontal condition (community periodontal index, CPI). The questionnaire, which was applied to the parents of the students, showed demographic, socioeconomic and behavioral profiles in order to contextualize the results. To verify the association between the dependent variables (prevalence of caries, fluorosis and periodontal condition) with independent variables (gender, race, type of school, location of housing, family income, parents ' education, oral hygiene habits and access to dental services) was used by bivariate analysis Chi-square test at significance level of 5%, and those variables that exhibited statistically significant association (p<0,20) were selected for analysis through Multivariate regression model of Poison. Results: the prevalence of dental caries was 56.31%, while that of fluorosis and periodontal condition was 9.5% and 15.2% respectively. The results showed low DMFT index (1.80) in 12 year old students in Nova Mutum/MT and the component Filled beats of Decayed, showing an increase in access to dental services. Statistically significant association was observed between the variable DMFT index and the variables type of school, race, family income, number of teeth brushing, use of orthodontic appliance, use of fluoride mouthwash, use of fluoride dental gel and dental consultation over the past 12 months. Both variables Fluorosis and Periodontal Condition, showed statistically significant association with gender and family income variables. Conclusions: in General, there were good oral health among schoolchildren assessed, however the DMFT index must be improved in order to achieve the recommended by WHO. Considering that dental caries, periodontal diseases and fluorosis are public health problems in the country, and that there is a lack of data on the prevalence of such problems in children and adolescents in the State of Mato Grosso, it is necessary the adoption of risk assessment tools and the addition of longitudinal care in Oral health policy of the municipality to ensure the maintenance of dental health of individuals, in particular those most vulnerable.
