[Epidemiological study of the incidence of dental caries]

The aim of this work is the evaluation of the results of an epidemiological survey on dental caries in schoolchildren in Arezzo and the province of Arezzo. The examined patients were 492, between the ages of 8 and 12, all of whom were at Primary School, in their third, fourth or fifth year. The evaluation of the data, which has been collected in other statistics in recent years, focussed on the measurement of caries in primary molars and upper incisors. The total occurrence of cases in which either the caries were present, or had already been cured, amounted to 62.4% of the total sample. It also seems as if there is a progressive increase in the instance of caries between the third year (45%) and the fifth year (68%) of Primary School. In addition it is worth noting that there is a higher incidence of caries among subjects in urban areas.
