OBJECTIVES: Chronic subclinical inflammation may elevate the risk of cognitive impairment. Periodontitis is associated with subclinical inflammation and accounts in part for tooth loss. The hypothesis was tested that periodontitis and tooth loss as a proxy of chronic periodontitis is associated with cognitive impairment in the elderly. SUBJECTS AND METHODS: The population-based Study of Health in Pomerania comprises 1336 subjects (60-79 years). Cognitive impairment was assessed with the Mini-Mental Status Examination (MMSE). Tobit regression analyses were adjusted for potential confounders. RESULTS: A decreased number of teeth was associated with lower MMSE scores in females (p
