The DMFT, DMFS and dfs indices were determined on a sample of 2,018 children, aged 6 to 15 years, representative of the Rhône-Alpes region. Plaque, calculus and gingival indices were also recorded. The results indicated that the caries experience in the deciduous dentition was important. The DMFT and DMFS indices increased with age. The DMFT increased from 1.03 +/- 1.50 at 6 years to 7.39 +/- 3.78 at 15 years and was higher in girls at the ages of 8, 14 and 15 years. The DMFS was higher in rural zones at the ages of 7, 12 and 14 years. The periodontal indices were generally low.
