title: [The sampling survey of denture restoration situation and its influence factors of the elders in Shanghai].
abstract: OBJECTIVE
  The prosthetic status and associated factors of the elders in Shanghai were evaluated to provide references for the government to issue related policies.
  
  
  METHODS
  The multi-stage stratified and isometric random sampling was used.The information of tooth loss and prosthodontic restoration was collected by oral examination in 788 elder residents aged between 65 to 74 years in Shanghai, and 325 subjects was randomly drawn from the given group to collect the information concerning socioeconomic factors and life health situation by means of interviewer administered questionnaire. A Logistic regression model(Stata.7.0) was used to analyze the related factors that have effects on whether or not those elders would choose to do the restoration.
  
  
  RESULTS
  The restoration rate of the patient was 61.73%. The restoration rate of the patients with the defect of dentition was significantly lower than that of the edentulous(P<0.01).The constituent ratio of the denture restoration with fixed denture, the removable denture, the fixed denture and removable denture, the full denture, the informal fixed bridge was 21.94%, 41.58%, 5.87%, 20.92%, 9.69%, respectively. The ratio of full denture, fixed denture and informal fixed bridge of the suburb elders was significantly higher than that of the urban ones(P<0.01). Logistic regression analysis revealed that the position of teeth defect, the gender and the number of missing teeth were significant predictors of denture or non-denture wearers.
  
  
  CONCLUSIONS
  Ratio of denture wearers is low in the older individuals with missing teeth in Shanghai. It is suggested that the government should take effective efforts to strengthen the people's oral health consciousness so that the elder patients could restore their lost teeth in time and more effectively.
