The Claim
Dysbiosis of the oral microbiome associated with periodontitis reduces nitric oxide bioavailability, increases oxidative stress, and upregulates adhesion molecules VCAM-1 and ICAM-1, leading to leukocyte adhesion and initiation of atherosclerosis.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Oral microbiome imbalance linked to gum disease reduces nitric oxide, increases oxidative stress, and elevates levels of VCAM-1 and ICAM-1 molecules, which cause white blood cells to stick to blood vessel walls and trigger atherosclerosis.
See the scientific wording
Dysbiosis of the oral microbiome, particularly associated with periodontitis, is linked to systemic endothelial dysfunction through reduced nitric oxide bioavailability, increased oxidative stress, and upregulation of adhesion molecules such as VCAM-1 and ICAM-1, which promote leukocyte adhesion and initiate atherosclerosis.
Bacteria from infected gums enter the bloodstream, invade blood vessel walls, and trigger a chain reaction that reduces a key molecule needed for blood vessels to relax, increases harmful chemicals that damage cells, and causes immune cells to stick to the vessel lining. This leads to fatty deposits forming inside arteries, which can rupture and block blood flow.
What the research says
1 studyBad bacteria in the gums can get into the blood and damage blood vessel lining, making it harder for vessels to relax and causing inflammation that leads to clogged arteries.
