title: Factors affecting caries experience in French adolescents.
abstract: Three hundred French 14-15-yr-old adolescents were randomly selected. They were examined clinically and caries experience was determined by using the DMFS index. The aim of this investigation was to evaluate children's habits using a self-administered questionnaire, to clarify the actual influence of well-known factors such as fluoride exposure, diet, oral hygiene and socioeconomic factors on caries experience and to stress those factors of primary importance. A multiple regression analysis revealed the variables which significantly contributed to explain DMFS scores in a final model: Age, sex, frequency of sweet consumption, use of standard or high fluoride toothpastes, bleeding during toothbrushing, living in St Yorre (F- = 0.45 mg/l). At a time when caries experience is decreasing, it seems that fluoride supply, snacking and oral hygiene are still independent and significant determinants of caries experience in French adolescents.
