[The sampling survey of teeth defect and denture restoration among 1579 middle aged and elder people in Shanghai].
OBJECTIVE
To investigate the condition of teeth defect and denture restoration among the middle aged and elder people in Shanghai and to analyse the variation tendency so as to provide relevant policy basis for the government.


METHODS
Multistage stratification isasteric random sample was used to acquire the teeth defect and denture restoration information among 791 people from 35 to 44 and 788 people from 65 to 74 years old, respectively. SPSS13.0 software package was used for data analysis.


RESULTS
The teeth defect rate of the middle aged and elder people in Shanghai was 21.0% and 81.0%, respectively. The mean permanent teeth number was 28.9 and 19.5. The edentulous rate of the elder people was 10.8%. The defect rate was highest in the molar area, and lowest in the canine agra. The denture restoration rate of the middle aged and elder people was 59.6% and 61.7%, respectively. The rate of the removable denture restoration was higher than that of the fixed denture. The rate of full denture, fixed denture and informal fixed bridge restoration in the suburb area was higher than that in the urban area(P<0.01).


CONCLUSIONS
The condition of teeth defect and denture restoration among middle aged and elder people in Shanghai is still unsatisfactory even though it has been getting better in the last decade. It is suggested that the government take efforts to lessen the teeth defect by control of caries and periodontal disease, and to improve the restoration level of the middle aged and elder people.
