Caries prevalence of preschool children in Baja, Hungary, in 1975 and 1982: effect of a supervised monthly NaF mouthrinsing program.
The aim of the study was 1) to compare the caries prevalence of preschoolchildren in Baja with data from 1975 and 2) to evaluate the effect of 0.2% sodium-fluoride mouthrinsings practiced during the last 4 yr. In 20 kindergartens of Baja 1462 children between 3 and 6 yr of age were investigated. All the children were participants in an oral hygiene motivation program and fluoride rinsings, performed generally monthly, but at least 10 times in a year. The dental investigations of the primary teeth were carried out by the same team as in 1975. The frequency of caries-free children increased from 18.8% in 1975 to 24.8% in 1982.
