Brushing teeth can reduce the risk of suffering from heart disease
Researchers from department of infectious diseases and public health of the University of London began the survey eight years ago. 11,869 Scottish residents with average age of 50 years attended this survey. They were requested to record the number of brushing teeth and the frequency. The results showed that 62% of respondents went to dental clinic every 6 months, 71% of respondents brushed their teeth twice a day. Overall, the oral conditions of respondents were in good state. The researchers found that about 555 respondents suffered from heart disease and 170 people died during eight years. Compared with those who never or rarely brush teeth, people who brush teeth twice a day had lower chance of suffering from heart disease. Reuters quoted the words of Professor Richard Watt that this discovery was not fresh, sepsis theory was raised in early 19th century, which suggested that oral infections can lead to systemic illness. At that time, pull out the teeth was the best treatment.
Researchers tested the blood samples from 4830 respondents. It was found that people with dirty oral cavity had more inflammation, which may result in heart disease. Previous studies have shown that 700 kinds of bacteria often appeared in dirty mouth and gums bleeding. Once the bacteria entered the blood circulation, it may activate the body's immune system, leading to inflammation and contraction at arterial wall. What's worse, it increased fat at artery, which narrowed blood vessels down and brought out cardiovascular disease." The latest research confirmed previous findings," Watts said, "there was relation between oral health and cardiovascular disease." Factors like smoking, obesity, genetic may lead to heart disease. The researchers ruled out these factors in this survey and found that cardiovascular disease associated with oral dirty.
Research report was published on the latest magazine called British Medical Journal. Warmsley, a consultant from British Dental Association, said there were many research proved that dirty mouth lead lots of diseases such as heart disease, diabetes and even Alzheimer. "We need further studies to determine the current view is just an accidental discovery or incontrovertible conclusions," Walmsley said. "but, it was certain that brushing the teeth with toothpaste contained fluoride twice a day for long-time, go to dental clinic regularly and eat less sweet foods, you can keep your mouth clean and enjoy happy life."
