Community and caregiver oral health education plus media campaign vs Pre-intervention baseline (and sites that discontinued the prevention program)

Reduction in prevalence of baby bottle tooth decay (BBTD) · Alaska Native and American Indian Head Start children

Community and caregiver oral health education was associated with a significant ~25% overall reduction in baby bottle tooth decay among Head Start children (certainty not graded).
