PDF: Factors associated with dental fluorosis

With the decreasing incidence of dental caries in Brazil since the 1980s, attention has been paid to the control of fluoride content and the quantity of ingested fluorides.

The latter has been associated with the increase in prevalence of dental fluorosis in regions with and without public water supply fluoridation.

Dental fluorosis often occurs at mild levels without greatly affecting dental esthetics or function, but the control of fluoride ingestion is considered important for the prevention of oral health problems in the general population.

Thus, oral health professionals should orient their communities to the correct use of fluorides in several 
presentations.

Recent national data indicate fluorosis prevalence rates of 8.5% in 12-year-old adolescents and 5% in 15-to-19-year-old subjects, confirming the fact that fluorosis is not a major public health problem in Brazil. Nevertheless, the prevalence of the disease is high in some cities.

Previous studies have demonstrated an association between dental fluorosis and sociodemographic factors. For example, an association between the quantity and frequency of topical sources of fluorides was observed in the countryside of the Rio Grande do Sul state in the South Region of Brazil. Other studies reported that fluorosis was associated with fluoridation of the public water supply.
