Epidemiological survey of caries occurrence in school age children

: In this paper a sample of 242 subjects has been examined in order to verify the frequency and diffusion of dental caries in some Elementary school of the Pavia district. The analysis of the outcomes obtained have showed substantial differences between this district and others formerly examined. However a significant decrease of DMF index has been noticed owing to notable work of information made by the teaching-staff. The need of an advertising campaign carried out by specialized staff is emphasized.
