Abstract

Objective
This study aimed to investigate the characteristics of the high-risk group for dental caries among 12- and 15-year-old children in Laos.
Methods
Oral health survey was conducted on 12-year-old (N=537) and 15-year-old (N=490) children in Laos. The oral examination data were listed from highest to highest based on the permanent caries experience index. Then the caries experience permanent index of the participants corresponding to the top third was calculated. In the final high-risk group, 179 and 163 children aged 12 and 15 years, respectively, were analyzed for the Significant Caries (SiC) Index.
Results
The Decayed, Missing and Filled Teeth (DMFT) index of 12-year-old children in Laos was 1.59 (urban area 1.72, rural area 1.46), and the SiC index of the high-risk group for dental caries was 3.93 (urban area 4.01, rural area 3.85). DMFT index of the 15-year-old group was 2.04 (2.37 in urban areas, 1.74 in rural areas), and the SiC index of the high-risk group for dental caries was 5.17 (5.90 in urban areas, 4.49 in rural areas).
Conclusions
Children aged 12 and 15 in the high-risk group for dental caries in Laos showed a higher caries experience permanence index than the overall average in the high-risk group. Based on the outcome of the investigation that the high-risk group had a lot of experience with dental caries, it is thought that the priority dental caries prevention project for the high-risk group of dental caries should be carried out.
