[Influence of ignorance of caries prevention on tooth health and behavior of junior high students].

Within the framework of an averaging study (clinical examination combined with written questionnaire) an attempt was made to determine the extent to which theoretical and practical knowledge of caries prophylaxis influences the behaviour and dental health of school children. Mean DF and DMF levels, it was demonstrated, are significantly reduced in children who know more; also, a higher percentage of children reported brushing their teeth more than once a day. In spite of this, a considerable discrepancy is noticed between knowledge and behaviour. Improved integration of dental hygiene instruction in the school day could improve school children's motivation to change their behaviour on a lasting basis.
