Summary
This bonus episode spotlights Perio Protect, a Cellerant Best of Class Hygiene Award winner, featuring Tanya Dunlap explaining the company's origin story and clinical approach. A dentist created the system to treat his mother's periodontal disease without surgery, developing a specialized tray with an internal peripheral seal that delivers medication deep into periodontal pockets. The key discovery was that hydrogen peroxide gel alone, originally intended as a propulsion agent for antibiotics, was independently effective at treating periodontal disease. At just 1.7% concentration, H2O2 breaks down biofilm protein chains, kills aerobic and anaerobic bacteria, and releases oxygen that changes the pocket microenvironment to favor healthy bacterial repopulation. The episode makes a compelling case for hydrogen peroxide as a dental home care tool, particularly as the profession moves away from antibiotics.
Key Points
- Perio Protect trays use an internal peripheral seal to deliver medication 8-10mm deep into periodontal pockets
- Hydrogen peroxide gel at 1.7% was discovered to be independently effective without antibiotics
- H2O2 breaks down protein chains in biofilm and bacterial cell walls
- The sealed tray builds oxygen pressure that changes the pocket microenvironment
- Oxygen-rich environments favor repopulation by healthy aerobic bacteria over pathogens
- Just 10-15 minutes of daily use produces substantial reductions in bleeding on probing
- 47% of American adults over 30 have periodontal disease, rising to 70% by age 65
- Dentists are the number one outpatient prescribers of clindamycin, which carries C. diff risk
Key Moments
How hydrogen peroxide was discovered to work without antibiotics
The accidental discovery that hydrogen peroxide gel alone was treating periodontal disease, originally intended only as a propulsion agent for antibiotics, led to research showing H2O2 breaks through biofilm and kills bacteria by disrupting protein chains.
"She said, I ran out of that months ago. I've just been using that gel, which was the hydrogen peroxide."
Oxygen therapy changes the periodontal pocket microenvironment
When H2O2 breaks down in the sealed tray, the released oxygen builds pressure and changes the microenvironment to favor healthy bacteria over pathogens.
"the tray is sealed. It's not letting the oxygen out. You're building pressure inside the tray."
