[Self-rated oral health: results of the World Health Survey-Primary Care in four municipalities in Rio de Janeiro State, Brazil, 2005].

Self-rated health is a subjective indicator that combines physical and emotional components and individual well-being. It has gained an important role in Public Health, with increasing use in the evaluation of the general population's health status. This study focuses on dental care and oral health status, including self-rated oral health, using data from 1,871 individuals 18 years or older, interviewed in World Health Survey-Primary Care, conducted in four municipalities in the State of Rio de Janeiro, Brazil. Bivariate logistic regression models were used to identify the determinants of 'excellent' or 'good' self-rated oral health. For both men and women, variables significantly associated with self-rated oral health were: per capita family income, frequency of dental visits, tooth loss, and use of dental prostheses. The results showed a socioeconomic gradient in self-rated oral health, precarious oral health among the elderly, and the importance of regular dental visits for maintaining oral health.
