Effectiveness of the school-based oral health promotion programmes from preschool to high school: A systematic review

Background Schools offer an opportunity for oral health promotion in children and adolescents. The purpose of this study was to conduct a systematic review of the influence of school-based oral health promotion programmes on oral health knowledge (OHK), behaviours (OHB), attitude (OHA), status (OHS), and quality of life (OHRQoL) of children and adolescents. Methods A systematic search on the PubMed and Embase databases was conducted to identify eligible studies. The last search was done on April 24(th), 2020. The quality of the included studies was evaluated using the Joanna Briggs Institute (JBI) Critical Appraisal tools. Results Of the 997 articles identified, 31 articles were included in this review. Seven studies targeted students in preschools, seventeen in elementary schools, and seven in high schools. Most of these studies revealed positive outcomes. Some studies showed that the school-based oral health promotion programmes showed better OHK, OHB, OHS, and OHRQoL. Conclusion Positive results were obtained through oral health promotion programmes in schools, especially those involving children, teachers, and parents.
