Abstract
The aims of this study were to estimate the prevalence of prosthetic requirements and dental treatment needs among the elderly Brazilian population and the associations with contextual and individual determinants. Data were taken from the Brazilian Oral Health Survey (SB Brasil 2010) and a sample of 7,619 Brazilian people aged 65-74 years were investigated. Multilevel logistic regression models were used to estimate the odds ratio (OR) and 95% confidence intervals between treatment needs and contextual variables (Municipal Human Development Index, Gini coefficient and oral health coverage in the Family Health Strategy) and individual (gender, income, education and skin color). The prevalence of treatment need ranged from municipalities (p < 0.05). Of the individual variables, gender was associated with dental treatment need (OR = 1.18, 95% CI 1.05 to 1.31); lower education and non-white skin were risk factors (OR = 1.18; 95% CI 1.05 to 1.31 and OR = 1.28, 95% CI 1.15 to 1.43); the non-white skin color represented a risk factor (OR = 1.83; 95% CI 1,38- 2,42) and for the need for prosthesis income was a protection factor (OR = 0.39; 95% CI 0, 30-.51). The results showed an association between the individual factors and treatment needs.

Summary
Trata-se de estudo quantitativo, analítico, de corte transversal, baseado em dados secundários oriundos do levantamento epidemiológico SB. Para a análise bivariada e multinível, em relação à necessidade de tratamento dental, foram excluídos os idosos edêntulos (n = 3.583) e os idosos sem informação (n = 110). A necessidade de tratamento dental foi categorizada em: “necessita ou não necessita”, e para sua determinação foram verificadas as questões do banco de dados do SB Brasil 2010 (NT1, NT2, NT3, NT5, NT6). Para a obtenção da distribuição espacial das necessidades de tratamento dos idosos no Brasil, dados das prevalências de necessidade de tratamento dos municípios (capitais e interior), de cada unidade federativa, foram submetidos ao software de geoprocessamento QGIS® (Creative Commons Attribution-Share) versão 2.1, juntamente com os índices de malhas digitais dos municípios brasileiros do Instituto Brasileiro de Geografia e Estatística (IBGE)[14]. Análise descritiva das variáveis contextuais, individuais e necessidades de tratamento em idosos, Brasil, 2010
