Prevalence and Prevention of Fluorosis in Children Living in the Districts of the Bukhara Region

Abstract

Fluorine is embedded in the structure of the main mineral substance of the tooth tissue – hydroxyapatite, which turns into a much harder fluorohydroxyapatite. Fluoride is especially important for the hardness of the tooth enamel. The recommended daily dose of fluoride is only 0.05 mg / kg, however, with an increase in the dose of fluoride by only 0.01 mg / kg, the risk of fluorosis increases significantly (Nikolishin A.K. 1999). The presence of high concentrations of fluoride in drinking water (1.5-12.0 mg / l) is the main etiological factor of fluorosis. The concentration of fluoride in water up to 0.5 mg / l, as a rule, does not cause any manifestations of fluorosis in the tissues of the teeth.
