Abstract

OBJECTIVE:

The aim was to study oral health in relation to cognitive impairment in the general population.

MATERIAL AND METHODS:

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.

RESULTS:

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).

CONCLUSION:

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.
