Gum Bacteria Reach a Calcified Valve
Preliminary human-tissue and mouse work links P. gingivalis with inflammation and calcium buildup in the aortic valve.
Summary
Preliminary human-tissue and mouse work links P. gingivalis with inflammation and calcium buildup in the aortic valve.
Researchers presenting at an American Heart Association meeting found more Porphyromonas gingivalis in calcified human aortic valves and reproduced valve accumulation and calcification in mice. Antibiotics or removal of the IL-1β pathway reduced effects in animals. The findings are a non-peer-reviewed meeting abstract and do not establish that dental treatment prevents valve disease in people.
