[Prevalence of dental caries in a school population of the Amazonian region]

In view of the lack of data as to the prevalence of dental caries among typical amazonian populations, the authors carried out an epidemiological study of 103 schoolchildren from Sirituba Island, Abaetetuba, Pará, Brazil. The mean values found for DMFT and deft were 6.5 and 5.4 respectively. Although the region is very primitive, this high prevalence may be linked to several factors, among which is the urban influence, mainly through the use of sugar, on food habits in such a way as fundamentally to alter the diet of the amazonian population.
