Relationship Between Periodontal Status and Cognitive Function of Rural Elderly in Taizhou
Objectives: To investigate the oral health status of the Taizhou imaging study, compare the differences of periodontal health status between different cognitive function groups, and explore the correlation between periodontal status and cognitive function.
Methods: The Taizhou imaging study was followed up in 2020. The social demographic background, health behavior and general health were collected through questionnaire survey. Mini-Mental State Examination (MMSE, Chinese version) and Montreal Cognitive Assessment (MoCA, Beijing version) were used to evaluate the cognitive function. According to the method recommended by the World Health Organization, the status of crown and root caries was collected by full-mouth examination. Periodontal examination was performed in half mouth randomly, including gingival bleeding index (GBI), calculus index (CI), probing depth (PD) and clinical attachment loss (CAL).
Results: A total of 547 subjects were included in this study, of which 95 cases (17.4%) in the normal cognitive group, 318 cases (58.1%) in the undefinable group and 134 cases (24.5%) in the impaired cognitive group. The prevalence rates of crown caries, root caries and severe periodontitis were 94.5%, 36.4% and 54.3% respectively. The calculus index (%) and clinical attachment loss in the normal cognitive group were the smallest among the three groups, and the difference was statistically significant (P < 0.05). Multivariate analysis was conducted with cognitive group as the dependent variable. The results showed that dental calculus index (%), education level, occupation and drinking history were the related factors of cognitive function (P < 0.05).
Conclusions: The overall periodontal condition of the Taizhou imaging study was poor, while a quarter had cognitive impairment. In terms of periodontal condition, only calculus status was significantly correlated with cognitive function.
