Motivational interviewing (MI) is a counseling strategy to help people change their behaviors. This single-blinded randomized controlled trial evaluated the effectiveness of MI in improving adolescents’ oral health | Journal of Adolescent Health
Fifteen secondary schools were randomly assigned to three groups: (I) prevailing health education, (II) MI, and (III) MI coupled with interactive dental caries risk assessment (MI + RA). Adolescents (n = 512) with unfavorable oral health behaviors (infrequent toothbrushing and/or frequent snacking) were recruited; 161, 163, and 188 in groups I–III, respectively. Participants in the three groups received their respective interventions. At baseline and after 6 and 12 months, participants completed a questionnaire on their oral health self-efficacy and behaviors. Their oral hygiene (dental plaque score) and dental caries (number of decayed surfaces/teeth status) were recorded.
MI was more effective than prevailing health education strategy in eliciting positive changes in adolescents’ oral health behaviors and preventing dental caries.
