Abstract

Tooth decay is a fairly common disease, causing consequences at many levels for oral health and general health. Therefore, with the purpose of helping dentists have a more general view of the current situation of dental caries in children, we conducted a study to describe the current situation of dental caries of 6-year-old students. This cross-sectional descriptive study was conducted in 191 6-year-old students (grade 1), who have been studying at Khuong Thuong Primary School – Dong Da – Hanoi. Results: The rate of tooth decay in children was 71.2%, of which the rate of primary tooth decay in female students was 80.9% and in male students was 63.6%. The rate of permanent tooth decay is 23.6%, of which the rate of permanent tooth decay in men is 27.1% and in women is 19.0%; dmft index = 3.46 ± 3.99; in which the dmft index in female students is 3.61 ± 4.08 and in male students is 3.34 ± 3.94. DMFT index = 0.35 ± 0.72, in which the DMFT index in male and female students is 0.40 ± 0.76 and 0.27 ± 0.66, respectively. Conclusion: The rate of tooth decay in children is relatively high, in which the rate of primary tooth decay in female students is higher than in male students and the rate of permanent tooth decay in male students is higher than in female students. The DMFT index of 6-year-old children is still high, in which the DMFT index of female students is higher than that of male students and the DMFT index is the opposite
