Stomatologic examinations of 1370 children aged 7, 12, and 15, determination of hygienic indexes in them, and anonymous questionnaires distributed among 154 parents and 64 pupils, as well as study of the efficacies of fluorine lacquer and gel have lead the authors to a conclusion that the level of dental caries intensity is low in children, but shows a tendency to growth. This necessitates introduction of a program of measures for the prevention of dental diseases and local administration of fluoride drugs, fluoride gel being the most effective of them.
