Abstract

Researching and analysising of tooth decay in children in the Mekong River Delta Region over the past two decades provides characteristics of the development of tooth decay in both primary teeth and permanent teeth as well as  preserving treatment status for children from 6 to 17 years old. Survey results show that primary tooth decay in children is at a high level in both caries rate and dmft index. Permanent tooth decay has increased with age over the past two decades. In 2019, permanent tooth decay in children decreased compared to 1999 in both tooth decay rate and DMFT index. Most primary tooth decay in children over the past two decades has not been treated. In 1999, most decayed permanent teeth in children were also untreated. In 2019, the rate of treated decayed permanent teeth in older children from 9 to 17 years old increased more than two decades ago but remained low, from 11.11% to 13.86%. With the results of the study, we recommend that children should be given dental preventive care for preschool children to improve oral health for them.
