Theory-based oral health education/promotion interventions (HBM, TPB, SCT, HAPA, TTM, PMT, SOC, PRECEDE-PROCEED, MI) vs Control (waitlist, routine/standard oral health education, or minimal intervention)

Self-efficacy related to oral health · school‐age children and adolescents

Theory-based educational interventions significantly improved oral health self-efficacy (SMD 1.49; low certainty), though between-study heterogeneity was very high.
