title: [The prevalence of permanent caries in adolescent in Sichuan province].
abstract: OBJECTIVE
  The aim of this survey was to obtain some information of the prevalence of dental caries in the youth aged 12, 15 and 18 years of Sichuan province.
  
  
  METHODS
  Based on WHO and national oral health survey standards, dental caries prevalence and treatment needs were investigated randomly in selected young individuals of Sichuan province in 1995.
  
  
  RESULTS
  The prevalent rates of caries of 12-, 15-, and 18-year-old adolescents were 28.47% and 36.40% and 39.54% respectively. The mean DMFT of 12-, 15- and 18-year-old were 0.52, 0.81, and 0.99. There are more pit and fissure caries than smooth caries in the young of 12-year-old than those of 15- and 18-year-old.
  
  
  CONCLUSIONS
  Despite improvement can be seen in adolescents' oral health in Sichuan, there remains a proportion of active untreated decays. Some simple prevention programs are needed to stabilize the caries.
