Khaberni - Although most individuals dislike undergoing root canal treatment (nerve treatment), a new study suggests that this common procedure may offer benefits beyond oral health, as it can improve cardiac and metabolic indicators and reduce the risk of heart disease and type 2 diabetes.
According to "The Washington Post," the study, published in the Journal of Translational Medicine, followed 65 patients at the Dental Institute at Guy's Hospital in London, who underwent root canal or post-root surgery to remove infection and inflammation from affected teeth. The researchers collected blood samples at five intervals: before treatment, three months later, six months, one year, and two years.
Before treatment, the patients, regardless of their overall health, showed elevated indicators associated with the risk of heart disease, including high blood sugar, disturbances in lipid levels, and signs of chronic inflammation.
After treatment, these indicators significantly improved, with decreases in cholesterol and fatty acid levels within three to six months. By the end of the two-year follow-up, most patients showed clear improvement in sugar and cholesterol levels and inflammation indicators.
The lead researcher, Sadia Niazi, a senior lecturer at King’s College London, said: "The presence of inflammation around the root apex can increase the risk of diabetes, heart disease, and other systemic health conditions. Successful treatment promotes healing and improves overall health and well-being."
Experts indicate that oral infections may allow bacteria to enter the bloodstream, leading to chronic inflammation that contributes to heart disease, diabetes, and other illnesses. These germs can also reach the lungs, causing respiratory infections, or the heart valves, leading to rare and dangerous conditions like endocarditis.
Although the study did not include a control group, and some improvements might be due to lifestyle changes, the results underscore the broader health impact of dental care. Niazi confirmed: "Root canal treatment is not just about saving a tooth; it can positively affect overall health."
Dentists and specialists encourage a bi-annual dental check-up, along with maintaining a healthy lifestyle including balanced nutrition, regular physical activity, and adherence to medications when there are chronic conditions.
Ultimately, experts hope that these studies will enhance collaboration between dentistry and other medical specialties, achieving an integrated approach that links oral care with general health.
