abstract: OBJECTIVE
  To investigate the prevalence of dental erosion and associated drinks in 12-year-old adolescence of Beijing.
  
  
  METHODS
  A random sample of 12-year-old adolescence of Beijing (n=844) was examined for dental erosion and required to fill a questionnaire of acidic drink intake. The grade criteria suitable for the survey of the dental erosion was used in the study.
  
  
  RESULTS
  The prevalence of dental erosion was 61.8%, of which mild enamel was 74.1%, severe enamel erosion 24.9% and dentine erosion 1.0%. Statistic analysis showed that a large amount of intake of carbonated drink or juice were risk factors.
