Background: The health of Russian Arctic residents has recently received special attention; however, information on the dental health of children in this region remains limited. Aim: To perform a systematic search and qualitative synthesis of scientific data on the prevalence and severity of dental caries in 12-year-olds in the Russian Arctic published in Russian and English over the last 25 years. Materials and methods: The scientific data were identified, selected, and presented according to the PRISMA 2020 guidelines. The literature search on the prevalence and severity of dental caries in 12-year-olds in Arctic and Subarctic Russia was performed using eLIBRARY.RU for publications in Russian and PubMed for publications in English, for the period from 1998 to 2023. Furthermore, information was gathered from national dental examination reports. Results: The initial search yielded 279 publications. Following screening and eligibility assessment using inclusion and exclusion criteria, 14 publications were selected for qualitative synthesis. According to the metaanalysis, the newly arrived residents in Salekhard had the highest prevalence and severity of dental caries among 12-year-olds, accounting for 98.33% (95% confidence interval [CI]: 95.04–99.97) and 7.82%, respectively. The lowest prevalence and severity of dental caries were observed in Segezha (Republic of Karelia): 54.98% (95% CI: 48.21–61.65) and 1.81%, respectively. The weighted prevalence based on systematic sampling was 79.33% (95% CI: 74.70–83.62). In the majority of cities where the assessment was performed at least twice, the prevalence of dental caries decreased over time; however, there were no significant differences. Conclusion: The study found that dental caries were more severe in 12-year-olds in the Russian Arctic than in other northern countries; however, the prevalence decreased over time without achieving statistical significance.
