Chlorhexidine

• Cationic

• Absorbed to Oral Tissue

• Substantivity/Reservoir

• Broad Spectrum

• Decrease Plaque

• Decrease Gingivitis

Chlorhexidine

Substantivity

• Binds to oral surfaces 30% retained

• Inhibits bacterial regrowth

• Released over time, binds for prolonged effect

One stage full-versus partial mouth disinfection in the treatment of chronic or generalized early onset periodontitis

I.

Long-term clinical observations

II. Long-term impact on microbial level

One Stage Full

Mouth Disinfection to Treat Periodontitis

Partial Traditional

Mouth Disinfection to

Treat Periodontitis

• RP 4 quadrants in 24 hours

• Chlorhexidine Rinse

2x/day

• Chlorhexidine Spray

Tonsils for 2 months

• RP each quadrant with 1-2 week interval

• No disinfection

One Stage Full VS Partial

Mouth Disinfection

Full Stage Gave:

• Greater PD !

• Greater AL "

Chlorhexidine

3 of 10

Cetylpyridium Chloride

• Increase cell wall permeability

• Cationic

• Some effect in reducing plaque and gingivitis

• Minimal substantivity

Fluorides

• Stannous Fluoride, Acidulated

Phosphate Fluoride, Sodium Fluoride

• Some antiplaque properties

• Some effect on gingivitis

• SnF

ADA accepted for anticaries, reduce tooth hypersensitivity

Stannous

Fluoride

Staining

Oxygenating Agents

• Anaerobic bacteria

• Anti-inflammatory

• Little effect on plaque reduction

• Little effect on gingivitis reduction

• Co-carcinogen/delay wound healing

4 of 10

Long-term use of hydrogen peroxide > 3% or 10% carbamide peroxide is discouraged

(especially in patients at risk for cancer)

Essential Oils

• Listerine and others: Thymol,

Menthol, Eucalyptol,

Methylsallicylate

• Alter bacterial cell wall

• Uncharged/low substantivity

• Reduces Plaque and

Gingivitis

• ADA Accepted

Triclosan

• Non-cationic

• In Dentifrices 0.2 - 0.3%

• Combine with zinc citrate, pyrophosphate or gantrez
