Cárie dentária e condições sócio-econômicas: um estudo transversal com jovens de 18 anos de Florianópolis, Santa Catarina, Brasil / Dental caries and socioeconomic conditions: a cross-sectional study among 18 years-old male in Florianópolis, Santa Catarina State, Brazil

ABSTRACT

The aim of this study was to assess the prevalence and severity of dental caries and need for treatment among 18 years-old males in Florianópolis, Southern Brazil. In addition, the associations between dental caries and socioeconomic conditions were tested. A cross sectional study was carried out. A random sample of 300, was selected from a list of Brazilian Army conscripts. Clinical data were collected according to World Health Organization criteria. Socioeconomic data (years of education of the subjects, their fathers and mothers and family income) were collected through interviews. The statistical significance of associations between socioeconomic indicators and dental caries prevalence were tested using the chi-square test whilst for severity of dental caries Mann-Whitney test was used. The prevalence of dental caries was 81 and the mean DMF-T was 4.5. The mean number of teeth that needed treatment was 1.2. Both dental status and treatment need were statistically significantly associated with socioeconomic indicators. Those with low levels of education and income experienced more disease and needed more treatment than those from high levels of education and income.
