[An epidemiologic study of the oro-dental status of children in the North of France, Pas de Calais and Picardy].
An epidemiological survey of dental caries prevalence has been conducted in North of France on a representative sample of 6 to 15 year old children. Six departments were studied: Nord, Pas de Calais, Somme, Aisne, Oise and Seine-Maritime. 2,772 children were randomly selected and examined. A dft index of 3,38 was found at 6 years which increased slightly until 8 years (3.71) and then decreased regularly to 0.57 at 12 years. The mean DMFT was 0.31 at 6 years, 4.10 at 12 years and 6.92 at 15 years. At the same ages, the respective values of DMFS were 0.56; 8.65 and 14.22. The plaque index increased up to 10 years (1.57), was stable from 10 to 13 years and decreased until 15 years. The calculus index increased up to 8 years. It was stable between 9 and 12 and increased again until 14 years. The gingival index varied in relation to age.
