Dental caries and gingivitis are common oral diseases in schoolchildren. This retrospective analysis was done to assess oral health problems and risk factors of children aged 6-14 years in selected primary school in Bangkok. Data of 509 schoolchildren were analyzed. The dmft index for grade 1 children demonstrated that prevalence of caries in primary teeth of grade 1 children was 82.6%. On the contrary, children in grade 2-6, high level of caries in permanent teeth was only 2.5%. Besides, gingivitis affected main group of children (76.8%). After logistic regression analysis found only poor oral hygiene significantly associated with dmft level (Adj OR=12.04, 95% of CI = 1.11-131.28). Gender, educational level and underlying diseases were significantly associated with DMFT level (Adj OR=2.32, 95% of CI =1.25-4.32, Adj OR=2.05, 95% of CI =1.04-4.06, and Adj OR= 4.09, 95% of CI =2.01-8.32, respectively). For gingivitis, school and oral hygiene were significantly associated factors (Adj OR= 3.5, 95% of CI =1.71-7.37, and Adj OR=19.09, 95% of CI =5.12-71.24) It indicated that early detection and prevention program should be provided for this group of children.
