Describe the current situation and the relationship between oral health care knowledge and tooth decay in 6-year-old students (grade 1) in Hanoi. Subjects and methods: The cross-sectional descriptive study was conducted on 191 6-year-old students (grade 1), studying at Khuong Thuong Primary School - Dong Da - Hanoi. Results: 94.8% of students who were surveyed said that the cause of tooth decay is due to eating a lot of biscuits, candies and soft drinks and 90.6% of students thought that tooth decay could be prevented. Only 12.6% (24/191) of children knew how to prevent tooth decay. 90.6% of students knew to choose the right type of toothbrush, but only 11.5% of students knew to brush all 3 sides of their teeth; 84.3% of students chose to brush their teeth for 2 minutes, and 93.7% of students chose to brush their teeth only twice a day. No relationship has been found between children's oral health care knowledge and tooth decay. Conclusion: Children's knowledge of oral health care is not good. More studies need to be conducted with larger and more diverse sample sizes to evaluate the relationship between children's oral health care knowledge and tooth decay.
