Aim: To examine the relationship between edentulousness and the socioeconomic and behavioural variables collected in a cross-sectional study of an elderly population.
Methods: The study was conducted on 277 elderly (60 years or older) in the municipality of Biguaçu, Southern Brazil. The oral examinations and questionnaires were conducted by two calibrated dentists. The criteria used followed the WHO and FDI standards.
Results: Prevalence of edentulousness reached 48.4%. A significant association was found in bivariate analysis for gender, satisfaction with appearance, time since last dental visit, the type of dental service sought in the last 5 years, educational level of the elderly and their children, and age of the elderly. In the multivariate analysis, gender, time since last dental visit and level of education of the elderly were significantly associated with edentulousness.
Conclusions: Female sex and low educational level were the main risk factors for edentulousness in this population. Although various Brazilian studies suggest a decline in edentulousness in the country, methodologically robust research into edentulousness in Brazil is still limited, demanding further studies into this highly prevalent yet preventable health problem amongst the elderly.
