title: Risk factors for dental erosion in a group of 12- and 16-year-old Brazilian schoolchildren.
abstract: BACKGROUND
  Dental erosion is a multifactorial disease and is associated with dietary habits in infancy and adolescence.
  
  
  OBJECTIVE
  To investigate possible associations among dental erosion and diet, medical history and lifestyle habits in Brazilian schoolchildren.
  
  
  METHODS
  The sample consisted of a random single centre cluster of 414 adolescents (12- and 16-years old) of both genders from private and public schools in Bauru (Brazil). The O'Brien [Children's Dental Health in the United Kingdom, 1993 (1994) HMSO, London] index was used for dental erosion assessment. Data on medical history, rate and frequency of food and drinks consumption, and lifestyle habits were collected by a self-reported questionnaire. Odds ratios with 95% confidence intervals were used to assess the univariate relationships between variables. Analysis of questionnaire items was performed by multiple logistic regression analysis. The statistical significance level was set at 5%.
  
  
  RESULTS
  The erosion present group comprised 83 subjects and the erosion absent group 331. There were no statistically significant correlations among dental erosion and the consumption of food and drinks, medical history, or lifestyle habits.
  
  
  CONCLUSIONS
  The results indicate that there was no correlation between dental erosion and the risk factors analysed among adolescents in Bauru/Brazil and further investigations are necessary to clarify the multifactorial etiology of this condition.
