title: [Sampling procedures of a national survey on the orodental status of 6-15-year-old children in France].
abstract: The multistage sampling procedure for the study of dental caries prevalence of 6 to 15 year old children of France consisted of 2 stratification variables and several levels of sampling. The geographical stratification controlled the distribution of the selected sample for the whole French territory. The second stratification variable consisted of the differentiation of urban and rural zones. The sampling rate was 1/400 and each schoolchild had the same probability of being selected. This rate gave samples of about 2,000 children for each age group, giving an adequate precision for the DMFT, DMFS and dft indices. This multistage sampling procedure was unbiased.
