Influence of cognitive impairment and dementia on oral healt
The aim of this study was to show the influence of cognitive impairment and dementia on oral health and on the utilization of dental services.

A cross-sectional analysis of data of the OrBiD pilot study was conducted. 137 subjects were stratified into five dementia groups on the basis of the Mini-Mental State Examination (MMSE) (1—no dementia (MMSE 28–30), 2—mild cognitive impairment (MMSE 25–27), 3—mild dementia (MMSE 18–24), 4—moderate dementia (MMSE 10–17), and 5—severe dementia (MMSE?<?10)). Information on the utilization of dental services and oral health parameters was collected.

- An increase in dementia resulted in a significant reduction in utilization. Moreover, with increasing cognitive impairment/dementia there was a significant difference in the number of teeth that were decayed, but not in the number of filled or missing teeth or the DMF/T index itself.

- With increasing dementia, the degree of restoration decreased and oral/denture hygiene deteriorated significantly.

- Nevertheless, periodontal therapy was required for all subjects independent of their degree of dementia while bleeding on probing was increasing with increasing dementia.

An influence of cognitive impairment and dementia on oral health and on the utilization of dental services was shown.
