Abstract. Background and Purposeâ Chronic infectious diseases may increase the risk of stroke. We investigated whether periodontal disease, including periodontitis and gingivitis, is a risk factor for cerebral ischemia.n conclusion, our study indicates that periodontal disease is significantly associated with cerebral ischemia.

Therefore, their identification as stroke risk factors that require further studies would have a major impact on stroke prevention.
