The Claim
Serum antibody titers against Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola are significantly elevated in patients with severe aortic valve disease compared to healthy controls, and these titers correlate positively with the clinical stage of periodontitis.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People with severe aortic valve disease have higher levels of antibodies against three specific bacteria linked to gum disease than healthy people, and these antibody levels increase as gum disease becomes more severe.
See the scientific wording
Serum antibody titers against periodontal red-complex bacteria (Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola) are significantly elevated in patients with severe aortic valve disease compared to healthy controls, and these titers correlate positively with the clinical stage of periodontitis.
Bad bacteria in the gums multiply and enter the bloodstream through damaged tissue, travel to the heart valve, stick to damaged areas, and cause the immune system to make antibodies against them. The more severe the gum disease, the more bacteria enter the blood and the higher the antibody levels become.
What the research says
1 studyStudy: Oral Dysbiosis Is Associated with the Pathogenesis of Aortic Valve Diseases
People with serious heart valve problems were found to have more antibodies in their blood against gum disease bacteria than healthy people, and those same bacteria were found in their heart valves — suggesting gum infections may be linked to heart disease.
