Effectiveness of various methods of educating children and adolescents for the maintenance of oral health: A systematic review of randomized controlled trials

Abstract

AbstractBackgroundSchool‐based oral health education has emerged as one of the most effective methods to instill a positive attitude toward oral health in children.AimThis systematic review (SR) aimed to assess the effectiveness of different methods of oral health education in children and adolescents.DesignSystematic search was conducted in PubMed, Cochrane, Web of Science, LILACS, Scopus, and EMBASE on January 29, 2023. Review included only randomized controlled trials (RCTs), and their risk of bias (ROB) was assessed by Cochrane RoB‐2. Data were extracted and analyzed by expert group. The GRADE approach was used to assess the quality of evidence for each outcome. Every step was conducted in duplicate, and disagreements were resolved by consulting the third reviewer.ResultsThe SR included 10 RCTs with majority showing a high ROB. They included 12 methods with the commonest being the use of leaflets/flash cards. Most interventions were effective in improving oral hygiene, gingival health, and knowledge except conventional teaching methods, lecture by using PowerPoint by dentists, and e‐learning interventions. The grade of evidence in the majority of outcomes was found to be low or very low.ConclusionInterventions using the interactive methods such as games, motivational‐experiential learning, and audiovisual methods were found to be more effective than controls and other interventions. Variabilities in study methods and outcome variables must be addressed in the future.
