title: [Epidemiological investigation on deciduous dental caries among children aged 2 approximately 4 years of Kaifu district in Changsha city].
abstract: OBJECTIVE
  To investigate dental caries of deciduous teeth among preschool children of Kaifu district in Changsha.
  
  
  METHODS
  According to the criteria recommended by the Third National Oral Health Investigation, deciduous caries of 459 children aged 2 to 4 were clinically examined. The mean decayed missing filled teeth (dmft) and the prevalence of dental caries for each age group were calculated. The Results were statistically analyzed using SPSS13.0 software package.
  
  
  RESULTS
  The prevalence of dental caries was 39.65%.The mean dmft score was 1.32. The prevalence of dental caries and mean dmft increased as children grew up (P<0.05).Dental caries of maxillary deciduous central incisor and mandibular second deciduous molar were significantly more common than other teeth. The filling rate was 7.57%, which increased with age. The prevalence of early childhood caries was 17.21% (17.90% for males and 16.34% for females). CONCLUSION Deciduous dental caries of preschool children are an important problem, and the filling rate is very low. Necessary measures for early prevention of dental caries must be taken.
