Abstract

Objectives: (1) Determine the rate and some factors associated with the dental caries condition among students. (2) Evaluate the effectiveness of the Infection Prevention Project through oral care for primary school students in Tra Vinh city. Materials and methods: A descriptive cross-sectional study combined with a non-controlled intervention study, using a total sampling method. The study was conducted from March 2022 to March 2025 in 17 primary schools in Tra Vinh city. Data was collected directly during examinations, evaluated according to the Health Policy Bureau, Ministry of Health and Welfare Okayama, Japan. Results: The rate of dental caries among students was 92.0%. The rate of deciduous tooth caries was 75.1% with a dft index of 4.46, and the rate of permanent tooth caries was 65.1% with a DFT index of 1.86. Factors related to permanent tooth caries include: age group with OR (95% CI): 2.30 (2.09-2.50), p<0.0001; gender with OR (95% CI): 0.69 (0.63-0.77), p<0.001; brushing frequency with OR (95% CI): 1.29 (1.07-1.54), p=0.006; brushing duration with OR (95% CI): 1.24 (1.03-1.49), p=0.025; having visited a dentist with OR (95% CI): 1.26 (1.08-1.47), p=0.017. The rate of dental caries after the intervention decreased to 89.0%. Conclusion: The high rate of dental caries shows improvement after intervention. There is a need to widely implement oral health programs and enhance dental education in schools. Collaboration with parents is also essential to improve students' knowledge, awareness, and behavior regarding oral health.
