title: [Caries prevalence and dental hygiene in a group of school-age children].
abstract: The results of a cross-sectional study of the prevalence of caries in a sample of 3,237 children aged 5 to 21 are described in relation to some objectives of the WHO program. The prevalence of caries is high in the sample: 1. 31.5% of the children aged 5 to 6 are free of caries (according to the WHO objectives, 50% of the children aged 5 to 6 should have no caries), 2. the mean number of decayed, missing and filled permanent teeth (DMF/T index) in children aged 11 to 12 is 6.6 (The DMF/T should be less than or equal to 3). The frequency of toothbrushing is distributed as follows: 23% of the children brush their teeth once a week or less, 46% brush their teeth once a day, and 31% brush their teeth twice a day or more. The purpose and the frequency of the consultations at the dentist's office have been examined: 15% of the children never consult the dentist, 44% consult the dentist in case of toothache, and 41% go to the dentist's office for screening or control. Only 3.2% of the children use regularly and appropriately fluoride tablets. Since the variance of the results is large, it is difficult to distinguish explaining variables or determinants. However, the data indicate that social groups show differences in DMF indices as well as in the behaviors associated with dental hygiene and prevention.
