The research arm of Gengyve
No one explains the oral–systemic connection this deeply.
Curated from Dr. S. Thaddeus Connelly's Oral Health Bulletin — written for clinicians and the curious. Every claim is tagged by how strong the evidence actually is. That honesty is the point.

We separate what is proven from what is promising
Oral Pathogens & Systemic Disease
Do Oral Pathogens Cause Systemic Disease? — Part I
P. gingivalis DNA turns up in arterial plaque, brain tissue, and tumors. That's a striking fact — and not the same thing as causation. This is where honest science earns its keep.
When Pathogens Rewrite the Rules — Part II
P. gingivalis ships concentrated virulence in nanoscale packets that slip across barriers whole bacteria can't cross — and dodge the immune system on the way. Meet the outer membrane vesicle.
Information Collapse
Information Collapse — Part I
Treat the body as a communication system and chronic gum infection becomes a signal-processing failure: persistent inflammatory noise that degrades the messages cells depend on. A new lens on an old disease.
System-Level Consequences — Part II
Once inflammatory noise corrupts the periodontal-vascular interface, it doesn't stay put. Shared mediators wire the body's systems together — and the whole becomes worse than the sum of its broken parts.
Clinical Biomarkers — Part III
A theory is only as good as the instruments that test it. Here are the biomarkers of the oral-systemic axis, sorted honestly by whether you can order them now, use them in research, or only imagine them yet.
Therapeutic Recalibration — Part IV
If chronic oral infection is a signal-fidelity failure, the goal of treatment shifts. Not eradication, but recalibration: quieting the noise at its source and letting the network re-tune itself.
Biofilm Architecture & Disease
Biofilm as a Structured Information System — Part I
The film on your teeth isn't a passive smear to scrape off. It's a spatially organized, chemically communicating microbial community that senses, decides, and remembers — a primitive information processor living in the mouth.
From Symbiosis to Dysbiosis — Part II
The shift from a healthy oral microbiome to a diseased one isn't gradual drift — it's a tipping point. And it can be triggered by a keystone pathogen too scarce to notice, whose power lies not in numbers but in influence.
Immune Signaling at the Biofilm Interface — Part III
In advanced periodontitis, the tissue damage isn't mainly the bacteria's doing — it's your own immune system, frustrated by a fortress it can't breach, spraying destructive enzymes into the gum it was meant to protect.
Systemic Coupling and Attractor States — Part IV
Dynamical-systems theory explains what clinicians see every day: periodontitis settles into a deep, self-defending stable state that resists treatment — and couples, through shared mediators, to stable disease states in the artery, the pancreas, and the brain.
