This cross-sectional study investigated the association between the presence of 20 or more teeth and sociodemographic and economic variables, use of dental care, and self-perceived oral health in adults. The sample consisted of 1,612 individuals aged 35 to 44 years, representative of the State of São Paulo, Brazil. In addition to the dental examination, subjects answered a questionnaire. Analysis in this study was limited to dentate individuals, divided into two groups (1 to 19 versus 20 or more teeth). The chi-square test and logistic regression were used (p < 0.05). Most individuals (72.1%) had more than 20 teeth. Less schooling was heavily associated with tooth loss, as were female gender, older age, rural residence, 5 or more people in the same household, low income, seeking treatment in the public health system, and seeking care due to toothache.251124072418Vargas, A.M.D., Paixão, H.H., Perda dentária e seu significado na qualidade de vida de adultos usuários de serviço público de saúde bucal do Centro de Saúde Boa Vista em Belo Horizonte (2005) Ciênc Saúde Coletiva, 10, pp. 1015-24Suominen-Taipale, A.L., Widstrom, E., Alanen, P., Uutela, A., Trends in self-reported use of dental services among Finnish adults during two decades (2000) Community Dent Health, 17, pp. 31-7Pinto, V.G., Epidemiologia das doenças bucais no Brasil (2003) Promoção De Saúde Bucal, pp. 25-42. , In: Kriger L, organizador.
