Objective: Describe the current situation of early childhood caries in 4-year-old children, at some kindergartens in Hanoi city, 2024-2025. Subjects and methods: A cross-sectional descriptive study was conducted on 296 4-year-old children, at kindergarten 10-10 (Tuong Mai ward - Hanoi city), Yen Vien and Anh Duong kindergartens (Phu Dong commune - Hanoi city). Results: The rate of early childhood caries is 80.4%; girls are 82.5% higher than boys 78.6%; suburban areas are 85.5% higher than inner-city areas are 75.5%. The rate of severe early childhood caries is 44.9%, of which the rate in girls is 50.4% higher than in boys 40.3%; and in suburban areas (55.2%) than urban areas (35.1%). The dmft index of 4-year-old children in the study group was 6.23 ± 5.84, the dmfs index was 9.96 ± 13.13. Conclusion: the rate of early childhood caries, severe early childhood caries and the dmft, dmfs index in 4-year-old preschool children in both urban and suburban areas were high, the dt and ds components accounted for the majority of the dmft, dmfs index, reflecting the insufficient level of attention to the condition of baby tooth decay in this group of children.
