A scoping review of cost-effectiveness analyses of school-based interventions for caries.

There is evidence to suggest that school-based caries preventive interventions are cost-effective, and in some cases cost-saving. Further evidence is required from low- to middle-income countries to confirm the generalizability of these findings. Future studies should consider adopting Quality Adjusted Life Years as a generic outcome measure that would enable the cost-effectiveness findings to be compared across different types of interventions and diseases. Improved standardization and quality of reporting are also required.
