ABSTRACT

Objective To analyze the current oral health status of middle-aged and elderly people in Wuhan,and to provide clinical evidence for preventing and promoting oral health among middle-aged and elderly people.Methods The data was col-lected from the annual health examination data system of Wuhan,which included 1994 patients aged 45～95.According to the World Health Organization(WHO)"Basic Methods of Oral Health Survey"(5 th edition),the data of caries,periodontal disease,dentition defect,dentition loss and denture restoration was mainly studied.Statistical methods such as Chi-square test and vari-ance analysis were used for data analysis.Results Among the 1994 subjects,1613 people(80.89％)were male and 218 people(10.93％)were older than 75 years old.The average numbers of caries and teeth loss were 2.68 and 2.03,respectively.The mean number of caries and tooth loss increased with age.The mean numbers of caries and tooth loss in 45～,55～,65～,75～,and 85～95 years old groups were 0.98 and 0.54,1.82 and 1.39,3.21 and 2.48,7.65 and 6.04,12.65 and 9.91,respective-ly.The difference among different age groups was statistically significant(P＜0.01).The proportion of restoration of teeth loss was also elevated with the increase of age(P＜0.01),and the difference of community periodontal index(CPI)among different age groups was also statistically significant(P＜0.01).The proportion of people in CPI1 group(shallow periodontal pocket)was decreased with the increase of age,while the proportion of people in CPI2 group(deep periodontal pocket)was increased with the increase of age(P＜0.01).Conclusion The overall oral health examination results of middle-aged and elderly people in Wuhan shows that the oral health status is slightly better when compared with the result of urban area in the 4th National Oral Health Examination.But caries,periodontal disease,tooth loss and unrepaired dentures are still serious in the elderly population.It is necessary to improve the prevention awareness of oral diseases in the elderly through regular oral examination,timely detection and treatment.At the same time,attention should be paid to dental restoration in the elderly population to improve the quality of life.
