Brushing your teeth can also clean your blood vessels, a new study reported in the US “Science Daily” a few days ago reminds that healthy teeth are also good for cardiovascular health. When there is plaque deposition in the blood vessels, it will gradually thicken the intima of the arteries and narrow the lumen, which is called “atherosclerosis”. This process also leads to heart disease, stroke and other cardiovascular and cerebrovascular diseases. major factor. Researchers at Mailman College of Columbia University in the United States conducted a survey called the “Epidemiological Study of Oral Infections and Cardiovascular Disease”, which regularly followed up 420 adults.
During the 3-year study period, the researchers observed that when a person’s oral and periodontal health improved, including regular brushing, flossing, regular visits to the dentist, scaling, etc., there was a reduction in arterial intima thickness about 0.1 mm. Previous studies have shown that if the carotid intima thickness increases by 0.1 mm over 3 years, the risk of coronary artery disease increases by 2.3 times. The study, published in the Journal of the American Heart Association, is the first to demonstrate that “reducing oral bacteria can directly slow and prevent the progression of arteriosclerosis.” The researchers speculate that oral bacteria may contribute to arteriosclerosis in a number of ways. On the one hand, bacteria in the oral cavity may directly damage blood vessels; on the other hand, when the oral cavity is unsanitary, the body’s immune response is intensified, and the inflammatory factors in the body increase, which will also “attack” the arterial intima. Therefore, the researchers suggest that timely improvement of periodontal and oral health, and removal of oral “garbage” such as plaque and calculus can effectively reduce the number of pathogenic bacteria, which is also equivalent to “brushing” the blood vessels. harmful materials.
