title: Allergic diseases, dental health, and socioeconomic situation of Swedish teenagers. Allergy, dental health, and social situation.
abstract: OBJECTIVE
  To study the association between allergic diseases (eczema, allergic rhino-conjunctivitis, and asthma), dental health, and the socioeconomic situation of Swedish teenagers.
  
  
  METHODS
  Cross-sectional survey with a questionnaire for allergic symptoms and parents' occupation (for socioeconomic classification); current dental status from the Public Dental Service. Bronchial reversibility test. Telephone inquiry of asthma cases.
  
  
  METHODS
  Primary care and a school in the centre of a middle-sized Swedish town (approx. 80,000 inhabitants).
  
  
  METHODS
  137 pupils of both sexes, 13-15 years old.
  
  
  METHODS
  Number of reported cases with allergic disease and outcome of bronchial reversibility test in relation to social class. Number of validated cases of asthma. Number of filled tooth surfaces in healthy and diseased cases.
  
  
  RESULTS
  Socioeconomic situation was found to associate with dental health, i.e. more fillings in lower social classes (P = 0.01), and with allergic disease, i.e. asthma and rhino-conjunctivitis (P = 0.05). Individuals from the upper social classes seemed prone to overreport asthmatic symptoms, whereas teenagers in the lower classes did the opposite, as indicated by five cases of pathologic values after bronchial reversibility tests in individuals who did not report asthmatic symptoms.
  
  
  CONCLUSIONS
  The study indicates that socioeconomic situation associates significantly with both dental health and allergic disease. No association was found between dental health and allergic diseases.
