Abstract

A survey of childhood dental caries in the South Central Coastal region of Vietnam was conducted over two decades, from 1999 to 2019, to provide useful information on the status of primary dental caries, permanent dental caries, as well as preventive care and restorative treatment for children. The results showed that: The prevalence of primary dental caries among children aged 6-8 years was high, ranging from 91.3% to 99.1%, with a mean number of decayed teeth per child ranging from 5.13 to 6.16. There was no decreasing trend in primary dental caries in this age group. Most decayed primary teeth were not conservatively treated to maintain them until natural exfoliation. The prevalence of permanent dental caries increased with age, both in terms of caries rate and DMFT index. Most children in the two younger age groups with permanent dental caries did not receive treatment over the two decades. In the two older age groups, the proportion of permanent teeth receiving restorative treatment was higher, but still remained low. After two decades, the prevalence of dental caries in the two older age groups decreased significantly, both in terms of caries rate and DMFT index. The number of decayed teeth receiving restorative treatment in these groups also increased, but remained at a low level.
