title: [A study on the epidemiology of permanent tooth carles in children aged 15 years in Anhui province].
abstract: OBJECTIVE
  The first study on the epidemiology of oral health status in AnHui province was held. The purpose of this survey was to investigate the prevalence of dental diseases and the needs of dental treatment, so as to develop effective programs in providing dental care in children.
  
  
  METHODS
  Non-proportional stratified cluster sampling was used for this study.
  
  
  RESULTS
  The results showed that XDMFT in this group was 0.95, permanent caries prevalence rate was 39.78%, lower than that of the same age children in other 11 provinces in Mainland(P < 0.001). The proportion of DMFT was 86.78%(D), 4.30% (M), 8.92% (F), respectively. The caries number that needed dental care were 1842 teeth(0.78 teeth per person).
  
  
  CONCLUSIONS
  The caries prevalence rate, the XDMF and the "F" were lower than the same age children in 11 provinces in Mainland and the "M" was higher.
