Product must be tested in randomized, parallel-group,
cross-over design and compared to a negative control
Must have minimum two 6-month studies, conducted
independently with indices recorded at baseline,
intermediate, and 6 months, and averaging 20% gingivitis
reduction
Statistically significant reduction of plaque and gingivitis
(compared to control)
Establish product safety (soft tissues, teeth, toxicology,
effects on oral flora)

MOUTHRINSES/MOUTHWASHES

Used as solvent for active ingredients
High content can cause hyper-keratotic lesions
Possible link to oral cancer? (inconclusive and still heavily debated)

cancer-risk-quantitative-meta-analysis-of-epidemiologic-studies
Conclusions:
This quantitative analysis of
mouthwash use and oral malignancy revealed no
statistically significant associations between
mouthwash use and risk of oral cancer, nor any
significant trend in risk with increasing daily use; and
no association between use of mouthwash
containing alcohol and oral cancer risk.
CHLORHEXIDINE
(8)
0.12% CHX
Peridex, Perio-gard and others
Cytoplasmic poison; causes rupture of cell membrane allowing leakage
Binds to mucins, reducing pellicle formation and inhibiting colonization
Binds to bacteria, inhibiting their
adhesion onto teeth
Substantivity: 12-24 hours
12% alcohol
35-40% decrease in plaque and gingivitis
