"Although periodontal disease is often considered a localized
infection, there is increasing evidence linking periodontitis to
systemic conditions such as cardiovascular disease, stroke,
respiratory diseases and adverse pregnancy outcomes. Evidence
suggests that periodontitis can be a systemic exposure that may
contribute to the development or progression of other diseases and
conditions. Periodontal intervention may
prevent the onset or progression of atherosclerosis-induced
diseases, such as myocardial infarction and ischemic stroke and may
help to prevent adverse preganacy outcomes."
