title: Impact of insurance scheme on adults' dental check-ups in a developing oral health care system.
abstract: OBJECTIVE
  To find out the relationship between dental insurance and demand for dental care, the present study evaluated impact of insurance scheme on adults' dental check-ups in a developing oral health care system.
  
  
  METHODS
  The target population included adults in the city of Tehran where the only telecommunication company provides 90% of the 1.9 million households with a fixed telephone. Of the 1531 subjects who answered the phone call, 224 were outside the target age (under 18), 67 said that they never had visited a dentist, and 221 refused to respond, leaving 1019 subjects in the final sample. Each interview lasted 15 minutes and was carried out using a structured questionnaire with fixed and open-ended questions.
  
  
  RESULTS
  71% of the subjects reported having dental insurance and 16% having visited a dentist for a check-up; 55%, more women than men, reported having had a dental visit within the past 12 months.
  
  
  CONCLUSIONS
  The present results revealed the positive relationship between insurance and demand for dental care. Those having dental insurance were more likely to go to check-ups despite their generally low rate found in this country with a developing oral health care system. In such countries, health insurance schemes should therefore include obligatory regular dental check-ups to emphasize prevention-oriented dental care.
