[Dental cavities in the urban, suburban, and rural environment among school children from the region of Dakar].

An epidemiological survey on 2.067 children from 7 to 12 years old in average carried in three urban, suburban and rural school environments, has shown that dental caries prevalence is not yet alarming in the district of Dakar, and that the caries index remain more high in the urban environment than in the rural environment. However face to the urbanization and the industrialization of this region, the modification of the alimentary habits appear to be facilitating factors of the raising of the dental caries prevalence in the coming years if nothing is done. It's why preventive measures have to be taken based over all on dental health education and dental health information in organized structures like school.
