Abstract
The purpose of this cross sectional study was to determine the prevalence, severity and primary dental caries pattern in 3-year-old children in Muang District, Nakhonsawan. A total of 546 children were examined by using WHO criteria. Descriptive statistics and chi square were used to analyze the data. The prevalence of caries, severe early childhood caries (dmft 24), molar-proximal caries and retained root were 60.8, 34.6, 12.1 and 15.4% respectively. Mean dmft and dmfs were 3.00+3.63 and 6.82–11.32. Children with severe early childhood caries were nine times more likely to develop posterior proximal caries (odds ratio = 8.82, 95%CI = 3.89 - 20.01). Upper central incisors were most affected by caries (49%) especially on the mesial surfaces (31.5%). The most affected occlusal surfaces were lower second right molars effective prevention programs are needed and should be implemented before the age of 3.
