Abstract

The objective of this study was to evaluate the clinical effectiveness and cost-effectiveness of oral-health promotion programs (OHPPs) aiming to improve children's knowledge of favorable oral health behavior to lower decayed/-missing/-filled teeth (DMFT) while reducing the financial cost on health institutions. An electronic search was performed in seven databases. Studies were restricted to human interventions published in English. The search study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, and the risk of bias was assessed based on the Drummonds Checklist. A total of 1072 references were found. Among these, 19 full texts were included. Most studies had a strong quality. The overall pooled impact of OHPPs estimates children suffering from DMFT/S to have 81% lower odds of participating in OHPP (95% CI 61-90%, I2: 98.3%, p = 0). Furthermore, the program was shown to be effective at lowering the cost in 97 out of 100 OHPPs (95% CI 89-99%, I2: 99%, p = 0). Three subgroups analyses (age groups, study countries, studies of the last five years) were performed to evaluate the influence modification on the pooled effect. A comprehensive analysis of the OHPPs confirmed a reduction effect on child DMFT, hence, lowering the financial burden of dental-care treatment on health institutions.
