Results based on 2,724 high caries risk patients with baseline caries risk assessment from 2007–2012
^aAdjusted models account for patient age, sex, payer type, race/ethnicity, provider type and year in training, calendar year, baseline decayed teeth, baseline number of teeth, losses-to-follow-up, and follow-up time
