Abstract

Objective: To describe the status of dental caries among primary school students in Đông Sơn District, Thanh Hóa Province, in 2022. Subjects and Methods: A cross-sectional descriptive study was conducted on 1,153 students from four primary schools in Đông Sơn District, Thanh Hóa Province. The status of dental caries in primary and permanent teeth was assessed according to the diagnostic criteria of the School Oral Health Program. Results: The prevalence of dental caries in primary and permanent teeth was 65.1% and 51.5%, respectively. The prevalence of primary tooth caries among first-, second-, third-, and fourth-grade students was 68.7%, 67.7%, 60.2%, and 52.2%, respectively. Corresponding rates of permanent tooth caries were 38.0%, 54.2%, 52.7%, and 45.4%. Overall caries prevalence across the four grades was 80.1%, 89.6%, 70.2%, and 82.1%. The prevalence of primary tooth caries, permanent tooth caries, and overall caries among boys and girls was 63.5%–45.8%–80.7% and 61.1%–48.3%–83.3%, respectively. No statistically significant differences were observed between sexes (p > 0.05). Conclusion: The prevalence of dental caries among primary school students in Đông Sơn District remains high in both primary and permanent teeth. No sex-related differences were identified. The findings highlight the need to strengthen preventive measures and oral health interventions for primary school students.
