A study found that good oral hygiene, such as brushing your teeth frequently, lowers the risk of cardiovascular disease.
Professor Jin-kwon Kim of Neurology at Yonsei University Yongin Severance Hospital and Professor Taejin Song of Neurology at Ewha University Seoul Hospital announced on the 29th that they have demonstrated a correlation between oral health and lipid levels in blood.
The research team observed 65,000 oral examination subjects for the national health checkup for about five years, and found that patients with periodontitis had a protective effect against cardiovascular disease, resulting in decreased HDL cholesterol levels. In addition, it was confirmed that triglyceride levels increased when there was a tooth defect.
Conversely, when brushing frequently, HDL cholesterol levels were high and triglyceride levels were low.
HDL cholesterol is called good cholesterol because it removes bad cholesterol accumulated in the walls of blood vessels. When HDL cholesterol is high, it helps smooth blood circulation and lowers the risk of angina and myocardial infarction.
In contrast, when triglycerides accumulate in the body, it can cause dyslipidemia such as hypertriglyceridemia.
On the other hand, oral diseases, including periodontitis, are known to cause localized oral inflammation as well as systemic inflammatory reactions, affecting the occurrence of various diseases such as diabetes and cardiovascular disease.
In fact, in previous studies, it was confirmed that the higher the incidence of diabetes and the higher the fasting blood sugar the more periodontitis or poor brushing.
Professor Kim Jin-kwon said, “Through this study, we have confirmed that there is a correlation between oral health and lipid levels in the blood,” and “proving that improving oral hygiene helps improve overall body health by lowering the risk of cardio-cerebrovascular disease. It has great significance in that it did it.”
