Compliance in a school-based caries clinical trial of a sugar-free chewing gum.

Unlabelled: There is currently little reliable and quantifiable compliance data reported for preventive trials of oral disease. During a two-year, school-based caries clinical trial of sugar-free chewing gum, strategies to promote compliance with a gum-chewing protocol were implemented and outcomes measured.

Methods: Over a 28-month period 2720 subjects, aged 11½-13½ at baseline, were recruited from 29 secondary colleges in Melbourne, Australia.

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.
