Periodontal disease: link to cardiovascular disease.

Poor oral hygiene that leads to dental infections could contribute to adverse medical outcomes such as cardiovascular disease. Twelve studies of varying degrees of design rigor have associated dental conditions, such as periodontal disease, missing teeth, and edentulousness, with either coronary heart disease or a cerebral vascular accident. Six of the studies were longitudinal so that the demonstration of the oral health parameters as significant predictors of the cardiovascular event would elevate the dental parameter to the status of a risk factor. Because dental diseases (especially periodontal disease) are treatable, the dental component is a modifiable risk factor; therefore, maintaining good oral health should receive the highest priority for a healthy life.
