Sugar-starch combinations in food and the relationship to dental caries in low-risk adolescents.

The aim of this 2-year prospective cohort study was to determine whether food-level sugar-starch combinations are predictors of dental caries in a low-risk adolescent population. A total of 645 subjects, aged 12-13 yr at baseline, were recruited from 25 secondary colleges in the north-west region of metropolitan Melbourne, Australia. Examinations to record dental caries status were conducted annually.
