title: [Analysis on oral health care utilization and expenditure of residents in Beijing].
abstract: OBJECTIVE
  To analyze the dental care utilization and expenditure of residents in Beijing, and to provide some basis on the policy of oral health insurance system.
  
  
  METHODS
  A cross-sectional survey was conducted among 1,517 subjects (urban area) and 1,878 subjects (rural area) of all age groups in Beijing selected by stratified, clustering, random sampling. The data of oral health care utilization and expenditure were collected in their home.
  
  
  RESULTS
  The number of the people who visited a dentist in a year were low both in urban area and in rural area, but the expenditure for oral health care per visit were quite high. The value of utilization of dental care in rural residents was 1/3 of that in urban residents, while the value of expenditure in rural people was about 1/2 of that in urban people. 2.07% incomes of rural residents were used for dental care per year, the corresponding value of urban residents was 1.77%. There was significant difference on the expenditure among those with different demographic, socio-economic backgrounds.
  
  
  CONCLUSIONS
  The expenditure for oral health care was high in Beijing, which accounted for quite a lot in average incomes per year. The burden of expenditure for dental care on rural residents was heavier than that on urban residents. The level of expenditure for dental care could provide some references for oral health insurance system in Beijing.
