Objectives: The purpose of this study was to evaluate the cost-effectiveness of two preventive interventions aimed at increasing the proportion of caries-free preschool children of low socioeconomic status using a decision analytic model.
Methods: Two scenarios were tested, one with a school milk program (SMP) and one without (non-SMP). Fluoride varnish (FV) and a probiotic (PB) were compared to a do-nothing alternative among children in public nurseries/schools over a 4-year period.
