[The incidence of caries in a school-age population sample of U.S.L. n. 15 Alta Val di Cecina-Volterra].

: It was made a screening on children of some filter classes (1st and 3d class of primary school and 1st class of secondary school) of the Volterra's schools to estimate the incidence of caries and, if necessary, to activate programs for an adequate prevention. We examined 749 children arrived to the Dental Department of the Sanitary District owing an invitation letter; a set of question was given to their parents testing mainly alimentary and oral hygienic uses of the children examined by dentists. Elaboration of data obtained from replies and demonstrated that caries incidence in our population is of 65.29%, prevailing on male sex, and that this pathology is predominant on people taking insufficient care of oral hygiene, making no use of fluoridated toothpaste and eating any of cakes (especially between meals). These data show the high incidence of caries in evolutional age and how much this is strictly connected with wrong alimentary and hygienic uses. Therefore, to reduce this phenomenon, it's necessary to operate interventions of sanitary education and dental checking examinations, at least every 6-12 months, beginning in preschool age.
