[An epidemiologic survey of the oro-dental health status of the child population in the middle Pyrenees region].
As part of a national survey, an epidemiological study of caries prevalence was conducted on 6 to 15 years old schoolchildren from the region Midi-Pyrénées. The analysis of a sample of 711 children representative of this regional child population showed no significant differences related to sex, age, rural and urban areas. The 6 years old children had a DMFT of 0.35 which rose to 2.35 and 4.58 at the ages of 9 and 12 years respectively. The DMFS indices were 0.43, 3.49 and 7.84 at the age of 6, 9 and 12 years respectively. At the age of 6 years, 87% of the children had no carious lesions. This percentage decreased rapidly to 33% at 9 years of age, 20% at 12 years and 7% at 14 years.
