PREVALENCE OF CARIES IN ADOLESCENTS IN RELATION TO DIET

The aim of the present study was to compare dietary habits between adolescents with high or low dental caries prevalence. All 15-yr-old adolescents living in a small community in Northern Sweden were studied in 1987, 1988, and 1989. The median values for energy and nutrient intake exceeded or were close to the recommendations (SNR89) given by the Swedish National Food Administration. The fiber intake did not reach the recommended daily amount even for the 90th percentile of the studied cohort. Nineteen percent of the adolescents had caries free teeth and 10% had nine or more decayed or filled surfaces. There was no difference in daily sucrose intake or average number of meals per day between these two groups. The group with nine or more decayed or filled surfaces had worse dietary habits, expressed as a higher fat intake, lower intake of complex carbohydrates, and lower density of iron (mg/MJ) than the group with no dental caries. Dietary counseling by dentists should be a valuable addition to other caries prophylactic measures taken by the dentists.
