Background: Poor oral and dental Health significantly affects public Health, impacting over half the world’s population. Dental caries can undermine children’s academic success and career prospects. Social inequities result in unequal access to oral Healthcare, particularly among populations with lower socioeconomic status (SES). National policies that improve access to oral Health can reduce these disparities. Objectives: This study aims to compile policies implemented by various countries to achieve universal Health coverage (UHC) for pediatric dental services. Methods: This scoping review was conducted according to Arksey and O’Malley’s framework and is reported using the preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews (PRISMA-ScR) guidelines. A systematic search was conducted on databases including Scopus, PubMed, Magiran, SID, Irandoc, Google Scholar, the WHO website, and the databases of Iran’s Ministry of Health. The search aimed to identify literature discussing governmental steps taken to achieve UHC for pediatric dental Health, published between January 1, 2011, and December 31, 2022. The results were charted and presented in a table. Results: This review included 22 studies. Six themes were identified based on the roles played by key players in this field, including schools, government policy and support, community-oriented preventive plans, insurance support, parents’ awareness, and inequality in accessing dental services. Conclusions: A comprehensive policy that reduces barriers to access, increases utilization, and engages all stakeholders—including parents, schools, and community centers—can effectively achieve UHC for pediatric dental Health.
