Abstract

Objective: To describe the status of dental caries and gingivitis in 15-year-old students before and after oral health education in 2023 and 2024 at Hoang Long Secondary School, Phu Xuyen, Hanoi. Subject and method: Prospective descriptive study. Result: The overall rate of gingivitis increased from 89.7% in 2023 to 96.2% in 2024, with the majority being mild to moderate gingivitis. The overall rate of dental caries increased from 81.25% in 2023 to 90% in 2024. The average DMFT (Decayed, Missing, and Filled Teeth) index significantly increased after one year (from 3.98 ± 4.063 to 7.06 ± 4.353), along with the average DMFS (Decayed, Missing, and Filled Surfaces) index (from 5.4 ± 6.139 to 10.73 ± 7.664). All tooth and surface parameters of caries, filled teeth, or missing teeth showed statistically significant increases after one year. The number of lesions evaluated with ICDAS (International Caries Detection and Assessment System) 1, 2, 3, 4, and 6 all increased (more than double) and were statistically significant. Conclusion: In the study group, the rates of gingivitis and dental caries increased rapidly within just one year following the community examination. Additional preventive and treatment interventions for dental caries and gingivitis are necessary, alongside oral health education programs, particularly for adolescents.
