Abstract

Objective. To evaluate the association between the number of teeth and cognitive functions adjusted for age and education level in a cohort of older adults living in Sweden. Materials and methods. The study employed a cross-sectional design in which 1147 individuals between 60–96 years underwent a clinical oral examination. The cognitive functions were assessed using Mini-Mental State Examination (MMSE) and Clock-test. The level of education was obtained from a questionnaire. Data were subjected to Chi-square tests and multivariate logistic regression analyses were employed, grouping the different variables into pre-determined categories. Results. The co-variables age and education were significantly associated with the number of teeth (p < 0.05). The multivariate logistic regression analysis revealed that the association between the number of teeth and the cognitive functions persisted even after adjusting for age and level of education. Conclusions. The findings suggest that the presence of teeth may be of importance for cognitive abilities in older adults.
