Effectiveness of Different Oral Health Interventions on Plaque and Gingivitis Incidence in Children Under Seven Years of Age: A Systematic Review and Meta-Analysis.

Oral health is crucial for young children, yet plaque and gingivitis pose significant challenges. This review evaluates oral health interventions for children under seven years to identify effective strategies. A systematic review was conducted across multiple databases using predefined criteria. Thirteen thousand five hundred records were identified, with 13 studies meeting the inclusion criteria. Various interventions were assessed, including tactile models, digital tools, fluoride varnish, and education programs. The meta-analysis showed heterogeneity in outcomes, with some interventions significantly reducing plaque and gingivitis. Tactile models and digital tools demonstrated effectiveness, particularly among children who were visually impaired and had congenital heart defects. However, fluoride varnish showed mixed results. School-based interventions and advanced toothbrushing technologies effectively reduce early childhood caries and plaque. Despite publication bias, a low risk of bias was observed across studies. The findings underscore the importance of tailored interventions and collaboration among stakeholders. Comprehensive oral health education, innovative digital tools, and multifaceted approaches are recommended to promote lifelong oral health habits. Further research is needed to standardize protocols and assess long-term effectiveness. Evidence-based interventions can significantly improve oral health outcomes for children under seven, laying the foundation for lifelong oral health.
