English 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.
