The fifth spoke in the preconception clinician wedge: the periodontal disease → preeclampsia evidence base for OB-GYNs and REIs, including the shared two-hit inflammatory model, who to screen at the preconception visit, and the case for preconception intervention over gestational treatment.

An evidence-based educational overview of ozone therapy in periodontics — how it works, what the evidence shows, which oral pathogens it targets, and where it fits in a comprehensive periodontal protocol.

An educational guide to laser therapy in periodontics — the three main laser types (Nd:YAG, Er:YAG, diode), how they work, what the evidence shows for LANAP and adjunctive use, and which periodontal pathogens they target.

An educational guide to Guided Biofilm Therapy (GBT) — the AIRFLOW, PERIOFLOW, and PIEZON protocol guided by biofilm disclosure, how it differs from traditional prophylaxis, what the evidence shows, and where it fits in periodontal maintenance.

The clinician capstone: a single ordering pathway that converts the four preconception evidence spokes (biomarkers, pathogens, male-partner, maternal periodontitis) into one actionable workflow for OB-GYNs and REIs — who to screen, what to order, how to interpret, when to treat, when to refer, and how to re-test.

The most-studied periodontal pathogen — found in arterial plaque, Alzheimer's brain tissue, and placental specimens. How P. gingivalis drives systemic inflammation through gingipains, where the evidence is strongest, and what you can do about it.

Periodontal pathogens transmit between intimate partners. A patient who reduces her oral pathogen load preconceptionally can be re-exposed by an untreated partner. Why couples' salivary screening belongs on the fertility workup.

Periodontal disease during pregnancy raises preterm birth risk by up to 7×. The preconception window is the last clinical moment to treat it before gestational physiology locks the inflammatory baseline. A citation-ready brief for OB-GYNs, MFM specialists, and periodontists.

A citation-ready clinician brief on the oral-to-placental pathway — FadA-mediated translocation, the P. gingivalis/red-complex preconception link, and which oral findings should trigger a referral.

The preconception window is the last routine clinical moment where oral pathogen load can be measured and treated before pregnancy hormones lock the inflammatory baseline in place. Here's why salivary diagnostics deserve a place on your preconception checklist.

Getting accurate saliva test results starts with proper collection. Here's exactly how to collect your sample — timing, prep, common mistakes, and what invalidates results.

Fusobacterium nucleatum is one of the most consequential oral bacteria — found in colorectal tumors, placental tissue, and linked to pregnancy loss. Here's what the research shows.

A complete guide to at-home saliva testing — what these tests measure, how to choose the right one, and what to do with your results.

The mouth is not just the start of digestion — it's a frontline diagnostic surface. Here's what an oral microbiome test actually measures, the three test types available, and the five systemic conditions most closely tracked to your oral bacteria.

Porphyromonas gingivalis is one of the most studied oral pathogens — linked to gum disease, heart disease, Alzheimer's, and pregnancy complications.

Not all saliva tests are the same. Here's how to decide between a salivary biomarker test and an oral pathogen panel based on your health goals.

Periodontal disease raises Alzheimer's risk by 1.5–3× — but the research is more nuanced than the headlines suggest. A detailed review of the oral-systemic connection, key studies, and what you can actually do about it.

Got your saliva test results back? Here's how to read them, what the bacterial levels mean, and what actions to take next.

A landmark year for oral-systemic research — from the first oral bacteria link to Parkinson's to flossing reducing stroke risk by 22%.

What salivary biomarkers actually measure in the preconception window — microbial load, inflammatory mediators, and the threshold logic behind the read.

How periodontal disease and oral pathogen burden raise preterm birth and low birth weight risk — and what the preconception visit can do about it.

How oral bacterial burden and periodontal inflammation worsen the insulin resistance at the core of PMOS (formerly PCOS) — and what the preconception visit can do about it.

Pregnancy gingivitis, enamel erosion from morning sickness, and periodontal disease that raises preterm birth risk by up to 7×. A trimester-by-trimester guide to safe, evidence-based dental care during pregnancy.

We're debating hormones while ignoring the environment they enter. The oral microbiome is the first ecosystem hormonal contraceptives encounter — and we're not assessing it.

Swallowing a gut probiotic won't fix your breath or your gums. The oral microbiome is a different ecosystem entirely — here's which strains actually work, why formulation matters more than CFU count, and the top products ranked by clinical evidence.

A $6 roll of pH strips can tell you more about your oral microbiome than most dental check-ups. Here's what salivary pH means, how to test it correctly, and when a low reading signals something worth investigating.

30% of infertility cases are classified 'unexplained.' New research points to something your OB-GYN and dentist have never discussed with you — and your saliva may hold the missing answers.

Understanding how the family microbiome is shared.

How hormonal shifts may influence gum sensitivity and inflammation.

How gum health may be linked to inflammation, circulation, and overall vitality.

How saliva may offer early insight into inflammatory and microbial patterns.

How gum inflammation may be associated with whole-body health patterns.

Up to 30% of infertility cases are labeled 'unexplained'—but could oral bacteria, inflammation, and partner microbiome sharing be part of the answer?

How a personal pregnancy loss led Dr. Najafi to salivary diagnostics — and why she now tests every patient for oral-systemic risk.

A personal conversation about discovering salivary diagnostics after pregnancy loss and how testing transformed my approach to patient care.
