New data of dental fluorosis in Senegal

ABSTRACT

Dental fluorosis isn't unknown in Senegal. With the implication of drilled-wells in the country for the satisfaction of the needs of the population in drinking water; the pravalence of disease has increased at the same time. To determine the relation between this increasing of the prevalence of dental fluorosis and the multiplication of the sinkings; we did an epidemiological study based on a comparative investigation of the rate of dental fluorosis in children using solely well-water or sinking-water for their alimentation. We did 25 sampling waters through 17 localities. In some localities; we did both sampling of well-water and sinking-water. In some others; we did only one of the two types of sampling; because it was the only one possible. We constitued also samplings of scholar children between 10 and 12 years aged. The analysis of the sampling-waters had been done at the Oral Biology Laboratory of Eastman Dental Center; Rochester; N.Y.; U.S.A. Correlatively; the epidemiological studies and the results of analysis show a relation between the prevalence of dental fluorosis in children using exlusively sinking-water and the level of fluoride contained in the studied waters
