title: [Study of dental caries and the influence of social-behavioral risk factors on dental caries of 1,080 15-year-old adolescents].
abstract: OBJECTIVE
  To describe the dental caries of 15-year-old adolescents in Hubei province, and to determine the influence of various social-behavioral risk factors on dental caries in the population.
  
  
  METHODS
  The survey employed a multistage, stratified, non-geometric proportional randomized sampling, representing adolescents aged 15-year-old in Hubei province. The epidemiological investigation of dental caries was made by clinical oral health examination. Oral health knowledge, attitude and behavior investigated by questionnaire.
  
  
  RESULTS
  The prevalence and mean DMFT in 1,080 15-year-old adolescents in Hubei province was 24.4% and 0.45, respectively. 11.4% of the adolescents brushed their teeth at least twice a day, 33.1% of the adolescents ever visited the dentists. A significant higher prevalence of dental caries was observed in girls (OR = 1.70). In addition, those who visit dentists and those who the scores of the consumption of sugar drink were high tended to have a higher prevalence of dental caries.
  
  
  CONCLUSIONS
  The dental caries prevalence of adolescents in Hubei province is low, but oral health habit of adolescents seems poor. Gender and consumption of sugar drink may be risk factors of dental caries.
