Taking care of your oral health will give you a winning smile and may also be heart healthy. Do you find this far-fetched to believe? It's true...A dirty mouth is like a factory dumping into a river. Using this analogy, the bacteria from your mouth is the sewage that can seep into your bloodstream, or in this case the river causing it to become polluted. Your bloodstream carries bacteria from the mouth and may cause the arteries of the heart to become polluted with periodontal bacteria. This can bring about inflammation of the arteries and possibly increase your risk of having a heart attack.
Periodontal researchers are racing to find out more about exactly how periodontal disease may affect heart disease. Recent issues of the Journal of Periodontology published findings about this topic. Following is a brief overview of these studies providing a pulse on the connection:
Levels of Oral Bacteria May Increase Risk for Heart Attacks
Two studies in the May 2005 issue furthered researchers' understanding about the potential link between the periodontal bacteria found in the mouth and heart disease. In one study, researchers found that the total number of periodontal bacteria was higher in individuals that suffered from a heart attack. In the second study, DNA of periodontal bacteria from the mouth was found in the plaque of the heart's arteries.
Researchers believe these findings may help confirm what they have long known - if there is a sterile pathway, such as a bloodstream near an infected area, the bacteria can travel to other parts of the body and cause harm.
Although more research needs to be done, periodontists are advising people to maintain good oral health.
Deep Periodontal Pockets Increase Risk for Electrocardiographic Abnormalities
In another study suggesting a relationship between periodontitis and cardiovascular disease, researchers found that people with deep periodontal pockets had an increased risk for Electrocardiographic (ECG) abnormalities. People with severe attachment loss also had a significant risk for ECG abnormalities.
Periodontitis is a chronic inflammatory bacterial infection. Past studies reported that when periodontitis is present, it elevates levels of other inflammatory substances such as C-reactive protein (CRP), interleukin-6 and neutrophils. This suggests that when these inflammatory substances are elevated, the risk of a cardiac event is also elevated.
Additional studies are required in order to examine the degree of cardiovascular risk from periodontitis compared with other risk factors. Because problematic ECG results are a widely appreciated risk factor for cardiovascular disease, it could be valuable to know if periodontal treatment could improve ECG exams. ECG exams cause no discomfort and take only a few minutes, so it's a common screening for heart disease. ECG abnormalities are a sensitive predictors of fatal coronary heart disease.
