Abstract

The study aims to identify the situation of caries in permanent dentition in Vietnamese children in 2019, thereby planning measures to prevent dental caries for children in the near future. A cross-sectional study with a sample size of 8053 children divided into  age groups (6-8; 9-11; 12-14 and 15-17 years old) was selected according to the randomized, multi-stage stratification method from 14 provinces representing the whole country by geographic regions. Caries in permanent dentition status was recognized by the tooth decay - loss - fillings index (DMFT) and the surface decay - loss - fillings index (DMFS) according to the World Health Organization criteria combined with the early tooth decay lesion of  ICDAS's index. The results showed that permanent caries appeared early and increased rapidly with age. The rate of caries was highest in the age group of 12-15 (43.7%) and on average, each child has 1 to 2 tooth decay without filling, the rate of treated teeth was very low. This result showed that it is necessary to promote dental health care activities for children.
