Gum disease and cardiovascular disease

Problem
The traditional risk factors such as smoking, diabetes, physical inactivity, high cholesterol and high blood pressure have caused only half of heart disease. Researchers have long tried to find other contributing causes to these diseases. Bacteria from the mouth may explain some outstanding cases.
Question
More and more evidence has accumulated in recent years indicating a possible link between certain chronic inflammatory conditions such as gum disease and cardiovascular disease. Although the causal relationship is not yet clear, this assumption is gaining credibility with the monitoring of patients and epidemiological investigations.
The Evidence 
Several studies show a link between gum disease and heart attacks. A Finnish study showed that men who suffered an acute myocardial infarction show a higher incidence of bacterial infection. Another study of 100 patients indicates that the dental health of patients with acute myocardial infarction was significantly worse than that of individuals in a control group. A study lasted seven years and about 214 persons has also shown that dental diseases were a significant way to predict the incidence of fatal coronary heart disease. It seems that the link between oral infections and heart disease occurs predominantly among individuals younger. In 1993, a large U.S. study on dental examinations of more than 10 000 people has concluded that the presence of gum disease increased the risk of heart disease significantly. The link was strongest among young men. There is evidence of a link between gum disease and stroke. A study of stroke and Dentistry over the past 10 years suggests that patients who suffered alchemic stroke had fewer teeth and greater bone loss around teeth that the control groups without stroke.
