Modeling the cost‐effectiveness of school‐based supervised toothbrushing program in reducing the dental caries burden in India

Abstract

BackgroundSupervised toothbrushing (STB) significantly reduces the incidence and progression of dental caries. School years present a favorable age for introducing such healthy habits for a lifetime.AimTo estimate the cost‐effectiveness of implementing a STB program in India in preventing dental caries incidence.DesignAn operational framework of a national STB program was devised. A mathematical model was then developed to evaluate this program's clinical effectiveness and economic impact in the Indian scenario. This study considered a hypothetical cohort of the Indian population aged from 6 to 75 years. Two groups were compared: no intervention and STB in government schools. The health outcomes assessed were a number of tooth caries incidences averted and quality‐adjusted life years gained.ResultsThe STB program in the government schools of India would prevent at least one tooth from developing caries in an individual's lifetime. Considering the current treatment‐seeking behavior, the STB program saves INR 153 (US$ 1.95) per carious tooth incidence averted and INR 22 202 (US$ 283) per QALY gained.ConclusionIn India, the school‐based STB program is expected to be a cost‐effective strategy for reducing the dental caries burden and its associated treatment costs.
