Abstract: PURPOSE: To investigate the periodontal health status and influencing factors of the elderly aged 65-74 years in Jiading District of Shanghai, and to provide data support for periodontal prevention and health care for the elderly in Jiading District. METHODS: A total of 961 elderly people aged 65-74 years old in Jiading District were selected by multi-stage, stratified, equal size and random sampling method, and oral examination and questionnaire survey were conducted. SPSS 22.0 software package was used for descriptive statistics and multivariate logistic regression analysis. RESULTS: Among 961 elderly people, the detection rate of periodontal pockets, bleeding on gingival probing, dental calculus and debris were 58.9%, 85.3%, 90.5% and 88%, respectively. The mean number of missing teeth was 6.25±5.94. The average number of gingival index, calculus index and debris index were 1.82±0.706, 1.26±0.632, 1.17±0.620, respectively. The results of univariate analysis showed that gender, education level, smoking, diabetes, cardiovascular disease, oral hygiene habits (frequency of brushing teeth and frequency of cleaning teeth) were risk factors for periodontitis in the elderly in Jiading District. Multivariate logistic regression analysis showed that smoking, diabetes and oral hygiene habits (tooth cleaning frequency) were independent risk factors for periodontitis in the elderly in Jiading District. CONCLUSIONS: The periodontal health status of the elderly aged 65-74 years in Jiading District is poor, and comprehensive prevention and treatment from various aspects and links should be carried out.
