title: [A survey of oral health-related quality of life and related influencing factors in elderly patients].
abstract: OBJECTIVE
  To investigate the oral health-related quality of life (OHRQL) and related influencing factors in elderly patients.
  
  
  METHODS
  A survey was conducted on a random probability sample of 250 elderly patients aged 55 years and over. The measures included the Chinese version of GOHAI, self-rated oral health, satisfaction with oral health and satisfaction with life. Socio-demographic and clinical information were collected. Multiple regression was used to analyze the related influencing factors.
  
  
  RESULTS
  Mean GOHAI scores of the sample was 12.26 +/- 7.67. Multiple regression equation was established. GOHAI scores = -6.477 + 0.309 x self-ratings of oral health +0.164 x number of missing teeth +0.237 x satisfaction with oral health +0.127 x satisfaction with life. The R square of the equation was 0.423.
  
  
  CONCLUSIONS
  Self-rated oral health, number of missing teeth, satisfaction with oral health and satisfaction with life are important variables influencing oral health-related quality of life in elderly patients.
