dentifrice Flashcards
7 components of dentifrice
- fluoride
- abrasive
- humectant
- binder
- surfactant
- flavoring agent
- sweetenders
abrasive agents
silicas
carbonates
phosphates
polishing agents
aluminum
calcium
tin
humectants
sorbitol
manitol
glycerin
propylene glycol
maintain moisture
prevent evaporation/hardening
increase shelf life
humectants
recommend toothpaste (with/without) fluoride
with
binders
natural gums: seaweed extracts
synthetic: cellulose
thickening agent
stabilizes (prevents solids from settling out)
binders
main reason why patients purchase
flavor needs to be pleasant immediate long lasting
sweetening agents non-cariogenic sweeteners
agents that serve as humectants
*sorbitol
*mannitol
*glycerin
surfactant (foaming agent)
detergent:
- stable/compatible
- some antibacterial properties
- flavor easy to mask
- low surface tension
- most common is SLS (sodium lauryl sulfate) (common thing happening are patients tissues are sloathing)
- products available without SLS
categoies of toothpaste,
therapeutic options:
others:
therapeutic options: anti-caries, anti-gingivitis, anti-hypersensitivity
others: baking soda, hydroxyaptite, anti-calculus, whitening, natural
all ada accepted toothpastes contain
fluoride
and NO SUGAR
therapeutic anti-caries toothpaste,
fluoride:
- sodium fluoride NaD- 0.22% at 1,000ppm
- sodium monofluorophosphate (MFP)- 0.76% at 1,000ppm
- stannous fluoride (SnF2)- 0.4% at 1,000ppm
**most OTC toothpastes are ____ppm
1,000
therapeutic anti-gingivitis fluoride:
stannous fluoride
stannous fluoride reported activity against:
- caries
- plaque-antimicrobial
- gingivitis- gingival bleeding
- calculus control
- sensitivity
therapeutic anti-hypersensitivity ingredients:
- potassium nitrate
- stannous fluoride
penetrates through the length of dentinal tubules (depolarizes sensory nerve endings)
potassium nitrate in anti-hypersens therapeutic toothpaste
blocking of exposed dentinal tubules
stannous fluoride
baking soda toothpastes contain
- sodium bicarbonate
- silicate
- fluoride
are no more effective than regular toothpaste
toothpaste with hydroxyapatite
- newer ingredient
- lab generated
3 non-toxic - biocompatible
- may be used in conjunction with fluoride
- often paired with xylitol
tartar control toothpaste
anti-calculus dentifrices
anti-calculus dentifrices use this to interrupt process of mineralization
soluble pyrophosphates
(crystalline growth inhibitors)
whitening toothpastes control stain via:
- physical methods
-abrasives: hydrated silica, titanium dioxide, activated charcoal - chemical mechanisms
-surface active agents or bleaching/oxidizing agents:
hydrogen peroxide, carbamide peroxide
