Eine Wurzelkanalbehandlung könnte den Blutzuckerspiegel deutlich senken, was darauf hindeutet, dass sie vor Typ-2-Diabetes schützen könnte. Zahnärzte stellten auch Verbesserungen des Cholesterin- und Fettsäurespiegels fest. Angesichts der weitreichenden gesundheitlichen Auswirkungen von Zahninfektionen sollte die Mundgesundheit in die allgemeine Gesundheitsversorgung integriert werden.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:

**Root canal treatment could significantly lower blood sugar levels, study suggests**

**Dentists also saw improvements in patients’ cholesterol and fatty acid levels, both associated with heart health**

If a looming root canal treatment is putting a dampener on the week, take heart: having the procedure can drive health benefits that are felt throughout the body, according to research.

Patients who were successfully treated for root canal infections saw their blood sugar levels fall significantly over two years, **suggesting that ridding the body of the problematic bacteria could help protect against type 2 diabetes.**

Dentists also saw improvements in patients’ blood cholesterol and fatty acid levels, both of which are associated with heart health. Yet more benefits were seen around inflammation, a driver for cardiovascular disease and other chronic conditions.

Dentists know that long-standing tooth infections can lead to bacteria entering the bloodstream. Once circulating, the microbes can increase inflammation and impair the body’s ability to control blood sugar levels. It was unclear, however, whether root canal treatment had benefits beyond clearing up the tooth infection.

Writing in the Journal of Translational Medicine, the researchers describe seeing meaningful changes after root canal treatment in more than half of the blood molecules they analysed. The results point to short-term improvements in fat metabolism and long-term improvements in blood sugar levels. Markers for inflammation, a driver for a multitude of chronic diseases, dropped after the dental procedure.

The findings are particularly important for global health, since chronic tooth infections often go untreated. According to the World Health Organization, 3.7 billion people globally live with untreated oral disease. **Given the broader health impact of tooth infections, oral health should be integrated into a patient’s general healthcare**, Niazi said.
