dentrifices-boles Flashcards
dentrifice components
abrasive agents
inactive component, high %
removes surface stains
Silicas
Carbonates
Phosphates
polishing agents
inactive, high %
gives teeth smooth feel
Aluminum
Calcium
Tin
toothpaste factors of abrasiveness
▪Hardness of abrasive
▪Size
▪Shape
pt factors of abrasiveness
▪Brushing Technique
▪Pressure of Brush
▪Hardness of bristles
▪Direction of brushing stroke
▪Number of strokes
humectants, names?
maintain what? prevent what? increase what?
high %, active
Maintain moisture
Prevent evaporation
Prevent hardening
Increase shelf life
Sorbitol
Manitol
Glycerin
Propylene Glycol
Binders
low %, active
Thickening Agent, Stabilizes, Prevents solids from settling out
Natural Gums
seaweed extracts
Synthetic Cellulose
flavoring agents
low %, most common reason pts choose a toothpaste
▪Flavor needs to be: Pleasant, Immediate, Long lasting
synthetic flavors/essential oils
Synthetic Flavors: Spearmint, Cinnamon, Wintermint, Peppermint, Vanilla, Citrus
Essential Oils
Thymol, Menthol, Eucalyptol, Methyl Salicylate
problem with cinnamon flavoring
can lead to sloughing
early sweeteners
honey/sugar=no good, cariogenic
sweeteners now
*Non-cariogenic sweeteners:
*Saccharin
*Cyclamate
Sorbitol
Mannitol
Glycerin
*Xylitol
** - Agents that serve as humectants
surfactants, common one now? why?
foaming agent, allows toothpaste to be spread about
Detergents used now
▪ Sodium lauryl sulfate (SLS)
▪ Stable/compatible
▪ Some antibacterial properties
▪ Flavor easy to mask
▪ Low surface tension
All ADA Accepted toothpastes contain:
No ADA Accepted toothpaste contains:
All ADA Accepted toothpastes contain Fluoride
No ADA Accepted toothpaste contains sugar
is all good toothpaste ADA approved
no
%/ppm
flouride systems used
*Sodium fluoride (NaF) - 0.22% at 1,100 ppm
*Sodium monofluorophosphate (MFP) – 0.76% at 1,000 ppm
*Stannous fluoride (SnF2) – 0.4% at 1,000 ppm
most OTC are what ppm
1000
stannous flouride
Reported activity against:
Research indicates superior efficacy:
Reported activity against:
- Caries
- Plaque
- Gingivitis
Research indicates superior efficacy:
- Antimicrobial
- Plaque**
- Gingivitis/gingival bleeding
- Calculus control
toothpaste with hydroxyapatite
- Newer ingredient
- Lab generated
- Non-toxic
- Biocompatible
- May be used in conjunction with
fluoride - Often paired with xylitol
anti hypersensitivty compounds
mechanisms?
ADA seal?
*Potassium Nitrate: Penetrates through the length of dentinal tubules and depolarizes sensory nerve endings
*Stannous Fluoride: Blocking of exposed dentinal tubules
*ADA seal for anti-hypersensitivity effects
anti-gingivitis compound
*Stannous Fluoride (Crest Pro-Health)
contain? seal? more effective?
baking sode toothpastes
Contain:
*Sodium bicarbonate
*Silicate
*Fluoride
*May have ADA seal
*NOT due to baking soda effects (F-)
*Baking soda toothpastes are no more effective than regular toothpaste
anti-calc toothpastes
compound/mechanism?
ADA seal?
▪ Tartar control toothpaste
▪ Crystalline growth inhibitors interrupt process of mineralization
▪ Soluble pyrophosphates
▪ ADA seal NOT awarded for anti-calculus claim
can whitening toothpastes get the ADA seal?
yes, for removal of surface stains
how do whitening toothpastes control the stain?
Physical Methods: Abrasives
Chemical Mechanisms: Surface active agents or bleaching/oxidizing agents
Polishing or chemical agents
that remove stains for whitening toothpastes
*Hydrated silica
*Titanium dioxide
*Hydrogen Peroxide
*Carbamide Peroxide
