The aim was to study oral health in relation to cognitive impairment in the general population.
The study population comprised 2320 persons aged 55 years or older who participated in a nationally representative Health 2000 Health Examination Survey in Finland. The data were collected by interviews and clinical oral examinations. Cognition was assessed using a shortened version of the Mini-Mental State Examination (score 0-16). Poisson regression models were used to estimate the relative risk (RR) for continuous variables and logistic regression models to estimate the odds ratio (OR) for dichotomized variables.
The results show that individuals with cognitive impairment have more carious teeth (MMSE 11-10: RR: 1.3, CI: 0.9-1.7, MMSE 9-0: RR: 1.5 CI: 1.0-2.4) than healthy persons. Furthermore, compared to cognitively healthy subjects, those with MMSE 9-0 more often have no teeth and no dentures (OR: 5.2, CI: 1.0-26.6) and less often good denture hygiene (OR: 0.4, CI: 0.2-0.7).
Cognitively impaired subjects among older adults in Finland have more carious teeth, are more often edentulous without using a denture, and have poorer denture hygiene than cognitively healthy persons.
旨在研究普通人群中口腔健康与认知障碍之间的关系。
研究人群包括2320名年龄在55岁及以上的人，他们参与了芬兰具有全国代表性的2000年健康检查调查。数据通过访谈和临床口腔检查收集。认知功能使用简易精神状态检查表的简化版本进行评估（得分0至16分）。泊松回归模型用于估计连续变量的相对风险（RR），逻辑回归模型用于估计二分变量的比值比（OR）。
结果显示，与健康人相比，认知障碍者有更多龋齿（简易精神状态检查表得分11 - 10分：RR：1.3，CI：0.9 - 1.7；得分9 - 0分：RR：1.5，CI：1.0 - 2.4）。此外，与认知健康的受试者相比，简易精神状态检查表得分9 - 0分的人更常没有牙齿且未佩戴假牙（OR：5.2，CI：1.0 - 26.6），而保持良好假牙卫生的情况则较少（OR：0.4，CI：0.2 - 0.7）。
在芬兰的老年人中，认知障碍者比认知健康者有更多龋齿，更常无牙且不佩戴假牙，假牙卫生状况也更差。
