ABSTRACT

Objectives: This study evaluated the impact of oral health education on children’s the caries status and plaque accumulation before and after education. Methods: Oral examination data from the first two years of the Seoul Metropolitan Oral Health Education Project were used included 914 and 896 participants from the 2023 and2024 data, respectively. Independent and paired t-tests were used to comparethe dental caries status and plaque accumulation before and after education. Results: A comparison of caries status by age and year showed no significant difference in the decayed-filled- teeth (dft) index of 3-year-olds (0.57±1.78 in 2023 vs. 0.41±1.49 in 2024). In contrast, a significant decrease was observed in 4-year-olds (1.72±2.85, 1.11±2.28). The Fluorescence Patient Hygiene Performance Index (F-PHPI) was significantly lower across all age groups in 2024. Among those who participated in the Infant Oral Health Education Project in both years, the dft index of the 3-year-olds significantly increased (0.53±1.50 to 0.99±2.05), while no significant change was observed in the 4-year-olds (1.81±2.91 to 1.83±2.73). However, the F-PHPI significantly decreased in both age groups. Conclusions: These findings confirmed that oral health education can effectively reduce plaque accumulation and prevent dental caries. To maintain these benefits, repeated education is recommended,along with structured programs involving parents and teachers.
