http://ebd.ada.org/en/evidence/evidence-by-topic/6066/mouthwash-and-oral-
cancer-risk-quantitative-meta-analysis-of-epidemiologic-studies
Conclusions:

A

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.

Q

CHLORHEXIDINE
(8)

A

 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

ALCOHOL-FREE CHLORHEXIDINE
(5)

A

 0.12% CHX

24
Q

CHX
(3)

A

 Most effective anti-plaque agent currently available
 Available with prescription only
 FDA approved (no longer carries the ADA seal of
approval due to a change in the program)

25
CHX on established biofilm will have only --- effects.
superficial
26
CHX is more effective when plaque is removed prior to ---.
rinsing
27
The biofilm will adapt and protect itself from the
effects of CHX.
28
CHX Inactivated by
toothpaste—important to rinse well with water prior to rinsing with CHX (or wait 30 min before rinsing with CHX)
29
DO NOT rinse with water immediately after rinsing with
CHX
30
CHX Recommend for patients who (2)
cannot or will not maintain adequate plaque control Post (periodontal) surgical cases
31
PHENOLIC COMPOUNDS (LISTERINE ANTISEPTIC AND ITS GENERIC EQUIVALENTS) (7)
 Active ingredients: Essential oils: thymol, eucalyptol, methyl salicylate, menthol  Original formula: 26.9% alcohol (Cool Mint: 21.6% alcohol)  Alters cell membrane, causing leakage and cell death  18-25% decrease in plaque and gingivitis  Low substantivity Rinse with 20ml, bid, for 30 seconds ADA approved (Antiseptic)
32
PHENOLIC COMPOUNDS (LISTERINE ANTISEPTIC AND ITS GENERIC EQUIVALENTS) SIDE EFFECTS (3)

LISTERINE ZERO (6)
 Introduced in 2010  “...powered by our 4 essential oils formula”  “...for patients who prefer an alcohol-free rinse”  This product is NOT Listerine Antiseptic without alcohol  COSMETIC  Contains essential oils for flavoring—they are NOT a therapeutic concentration
35
CETYLPYRIDINIUM CHLORIDE (CPC) (.05% COSMETIC CONCENTRATION) (4)
Ingredient in many OTC ‘cosmetic’ mouthwashes (.05%) Quaternary ammonium compound Marginally effective in reduction of plaque and gingivitis Little to no substantivity
36
CETYLPYRIDINIUM CHLORIDE (CPC)(.07% THERAPEUTIC CONCENTRATION) (4)
ie: Crest Pro-Health Rinse Multi-Protection Rinse* // Crest Gum Care //Colgate Advanced Pro-Shield no alcohol Studies indicate plaque and gingivitis reduction comparable to Listerine Antiseptic. Mechanism of action: ruptures cell wall; also may alter bacterial
37
Both products contain
.07% CPC
38
CPC VS CHX (2)
 CPC binds to tooth structure and plaque, but not as strongly as CHX binds to them  CPC is rapidly released from binding sites so it is not as efficacious as CHX
39
HYDROGEN-PEROXIDE-BASED (4)
 1.5% hydrogen peroxide  Alcohol free  Cleanses oral wounds, irritations  Preliminary information reported H2O2 to be effective against COVID *More investigation: Data does not currently support

VIADENT FORMER active ingredient:
sanguinarine (blood root plant)
41
VIADENT (5)
 In the mid to late 90’s, higher than normal incidence of leukoplakia was seen.  Sanguinarine determined to be cause.  Pts were 8-11 times more likely to develop leukoplakia  Lesions seen in former users-5 yrsafter use  Risk was highest in patients who used both mouthrinse and toothpaste
42

Marketed as pre-brushing rinse Ingredients: surfactants (detergents), sodium bicarbonate, glycerin, alcohol (7.5%) Non-toxic, non-irritating, no enamel damage Claims are unsubstantiated with sound research “The data provided do not support the use of PLAX dental rinse as part of an oral hygiene program.”*
43
SMART MOUTH (4)
 Claim: “Eliminate & Prevent Sulfur Gas, Never have bad breath again”  Active ingredient: zinc  What does the evidence say? Evidence is unclear. Potential efficacy is weak.  Should be marketed as an ‘oral deodorant’

What does the Evidence Say?  Jauhari, D, et al: Comparative evaluation of the effects of fluoride mouthrinse, herbal mouthrinse and oil pulling on the caries activity and streptococcus mutans count using Oratest and Dentocult SM Strip Mutans Kit. Int J Clin Pediatr Dent, 2015  52 healthy children, ages 6-12, divided into four groups  Fluoride (200ppm NaF)  Herbal (Salvadora Persica)  Oil pulling  Control  Estimation of caries activity and S. mutans done prior to and following respective rinsing for 2 wks  Conclusions: (2)
 Fluoride and herbal rinses were comparable. Both equally effective in reducing caries activity and S mutans  Oil pulling did not provide any additional benefit as an effective antimicrobial agent in reducing bacterial colonization
