PHOENIX: Tooth loss in adults worldwide, particularly in the elderly population, is primarily caused by severe periodontitis, a common peripheral infection and inflammation. Periodontitis leads to the destruction of tooth-supporting tissue and alveolar bone, and is also related to systemic inflammation. The latter is a well-documented risk factor, among others, for Alzheimer’s disease.
The present study, led by the Professor Jin Lijian from the University of Hong Kong, points out that multiple tooth loss does not only indicate poor oral health, but also could be a sign of Alzheimer’s disease or dementia.
Researchers examined and evaluated 161 acute ischemic stroke patients (mean age 63.8) for medical, oral and cognitive conditions. They found that the patients who had a higher amount of tooth loss of around eight teeth tended to get lower scores on the Montreal Cognitive Assessment, a test designed for clinicians to detect cognitive impairment.
The subjects with higher number of missing teeth also exhibited a significantly higher proportion of VCI than those with seven or less missing teeth…
