ABSTRACT
BACKGROUND:
Evidence of the cost-effectiveness of school-based first permanent molar sealants programs is not yet fully conclusive. The aim of this study was to determine the incremental cost-utility ratio (ICUR) of school-based prevention programs for the application of sealants in molars of schoolchildren compared with non-intervention.METHODS:
A cost-utility analysis based on a Markov model was carried out using probability distribution. The utility was measured in quality-adjusted tooth years (QATY). The assessment was carried out from the public payer's perspective with a six-year time horizon. Costs and benefits were discounted at 3% per year. Only direct costs were evaluated, expressed in Chilean pesos (CLP) at 7th May at 2019 values (exchange rate USD = CLP 681.09). Univariate deterministic sensitivity analysis and probabilistic analysis were carried out.RESULTS:
After a six-year follow up, the cost of sealing all first permanent molars was found to be higher than non-intervention, with a mean cost difference of USD 1.28 (CLP 875) per molar treated. The "seal all" strategy was more effective than non-intervention, generating 0.2 quality-adjusted tooth years more than non-intervention. The ICUR of the "seal all" strategy compared to non-intervention was USD 6.48 (CLP 4,412) per quality-adjusted tooth years. The sensitivity analysis showed that the increase in caries was the variable which most influenced the ICUR.CONCLUSIONS:
A school-based sealant program is a cost-effective measure in populations with a high prevalence of caries.Palabras clave
