Forthcoming · Oral Intelligence by Michael Gulizio, DMD, MSEd, MSciDent

The clearest window into your health and longevity is your mouth.

Breathing, sleep, the microbiome and chronic inflammation all meet in the mouth, yet most of medicine still treats it as a separate department. Oral Intelligence makes the case that it is one of the earliest and most readable signals of how the whole body is aging.

The gap

Your dental visit was built to answer one question.

Are there holes in the teeth. Everything else the mouth can tell you goes uncollected.

Not out of negligence, but because no one is asking for it. Training, reimbursement and the design of the appointment all point the same way. Meanwhile the literature on what the mouth reveals about the heart4,9, the brain5, metabolism13 and sleep2 has moved a long way past the chair.

That gap, between what the science establishes and what happens at a dental visit, is the subject of the book.

The pathogen map

From the gumline to distant disease.

Four oral culprits, seven conditions, and the published evidence connecting them. Select any organism or condition to see what has been found, and how strong the evidence is.

How to read this map

Select an organism or a condition.

Each line is a published finding, labeled by the strength of its evidence. Association is not causation; the label tells you what kind of evidence stands behind each line.

Randomized trialProspectiveMechanisticAssociationReviewCase report
Oral organism

Porphyromonas gingivalis

A principal periodontal pathogen. It produces gingipains, protein-cutting enzymes, and an enzyme (PPAD) that citrullinates human proteins.

  • Cardiovascular diseaseAssociation

    DNA of P. gingivalis detected inside human atheromatous plaque.4

  • Alzheimer's diseaseAssociation + animal

    Gingipains found in Alzheimer's brain tissue, tracking with tau; oral infection in mice reached the brain.5

  • Pancreatic cancerProspective

    Oral carriage associated with higher later risk of pancreatic cancer.8

  • Rheumatoid arthritisMechanistic

    Its PPAD enzyme citrullinates human proteins, the targets of rheumatoid autoantibodies.10

Oral organism

Fusobacterium nucleatum

A common oral anaerobe that bridges other species in dental plaque. Its FadA adhesin binds E-cadherin on human cells.

  • Colorectal cancerAssociation + mechanistic

    Enriched in colorectal tumors; FadA activates β-catenin growth signaling.6,7

  • Adverse pregnancy outcomesCase report

    One documented case traced an oral strain to a term stillbirth.12

Oral organism

Aggregatibacter actinomycetemcomitans

Associated with aggressive forms of periodontitis. It produces leukotoxin A, which damages white blood cells.

  • Pancreatic cancerProspective

    Oral carriage associated with higher later risk of pancreatic cancer.8

  • Rheumatoid arthritisMechanistic + association

    Leukotoxin A drives hypercitrullination in neutrophils; exposure associated with RA.11

Oral organism

Periodontitis: the dysbiotic gum community

Not a single organism: chronic inflammation driven by an imbalanced bacterial community below the gumline.

  • Type 2 diabetesReview

    A two-way relationship: each condition worsens the other.13

  • Cardiovascular diseaseRandomized trial

    Intensive periodontal treatment improved blood-vessel function at six months.9

Condition

Cardiovascular disease

Atherosclerosis and blood-vessel function.

  • P. gingivalisAssociation

    DNA of P. gingivalis detected inside human atheromatous plaque.4

  • PeriodontitisRandomized trial

    Intensive periodontal treatment improved blood-vessel function at six months.9

Condition

Alzheimer's disease

Progressive neurodegeneration with amyloid and tau pathology.

  • P. gingivalisAssociation + animal

    Gingipains found in Alzheimer's brain tissue, tracking with tau; oral infection in mice reached the brain.5

Condition

Colorectal cancer

Cancer of the colon and rectum.

  • F. nucleatumAssociation + mechanistic

    Enriched in colorectal tumors; FadA activates β-catenin growth signaling.6,7

Condition

Pancreatic cancer

Usually diagnosed late, when treatment options are limited.

  • P. gingivalisProspective

    Oral carriage associated with higher later risk of pancreatic cancer.8

  • A. actinomycetemcomitansProspective

    Oral carriage associated with higher later risk of pancreatic cancer.8

Condition

Rheumatoid arthritis

Autoimmune joint disease marked by antibodies to citrullinated proteins.

  • P. gingivalisMechanistic

    Its PPAD enzyme citrullinates human proteins, the targets of rheumatoid autoantibodies.10

  • A. actinomycetemcomitansMechanistic + association

    Leukotoxin A drives hypercitrullination in neutrophils; exposure associated with RA.11

Condition

Type 2 diabetes

Impaired glucose control and insulin resistance.

  • PeriodontitisReview

    A two-way relationship: each condition worsens the other.13

Condition

Adverse pregnancy outcomes

Including preterm birth and stillbirth.

  • F. nucleatumCase report

    One documented case traced an oral strain to a term stillbirth.12

The book in six parts

From mechanism to action.

How you breathe, what lives in your saliva, what regeneration can and cannot do, and what to ask for at your next appointment.

Part VI · The assessment

ORIGIN™ reads the mouth as one system.

Six domains, assessed in sequence, combined into a single picture of systemic risk. The book conceptualizes it; the practice runs it.

Six domains, one reading

Select a domain.

ORIGIN assesses each domain in sequence, because each finding changes how the next is read. Tap a number on the wheel or a domain below.

Domain 01

Microbiome

Salivary analysis of the bacterial community and the specific pathogens with documented systemic associations.

Domain 02

TMJ & function

The jaw joints, the bite and how the system moves under load.

Domain 03

Neuromuscular

The muscles of the head and neck, pain patterns and the signals driving them.

Domain 04

Imaging

Structural views of joints, bone and airway that the eye cannot see in the chair.

Domain 05

Airway

Breathing pattern, airway anatomy and sleep-disordered breathing risk.

Domain 06

Biomarkers

Inflammatory and stress markers, including salivary cortisol, that place the oral findings in the context of the whole person.
