The Role Of Fluoride In Caries Management Flashcards
(52 cards)
What concentration of fluoride has low mottling
1ppm of fluoride
if water is fluoridated what conc of fluoride is in the water
0.7PPM
what does DMFT mean
decayed missing filled teeth
what does the graph of fluorosis and DMFT show
that with the ppm of fluoride increasing there is only a slight decrease in DMFT
but the severity of fluorosis greatly increases
where is fluoride absorbed in the body
mainly in the stomach
what type of absorption is fluoride absorbed by
systemic absorption
where does excretion of fluoride happen
in the kidneys
how is fluoride absorbed into the blood
as HF
where is fluoride incorporated
in calcified tissues such as bones and teeth
where does fluoride also enter
saliva
how does fluoride work
decreases demineralisation of enamel
increases remineralisation of enamel
incorporated in developing enamel
interferes with metabolism of some plaque bacteria
what are some examples of bacteria ghat cause caries
strep mutans
lactobacillus
what is the critical ph of enamel
5.5
how long does it take to get the ph of the mouth back up to normal after an acid attack
around an hour( some notes say 20-40 mins)
what does acid demineralisation cause in the enamel crystals
porosities
why does the lesion appear chalky
due to the fact that light is refracted differently of those enamel porous crystals leaving a chalky appearance
what ions are important for remineralisation
calcium
phosphorus
fluoride
will demineralised enamel take fluoride up
yes
where can we get calcium and phosphate from
saliva
dairy food
CPP-ACP mousse
what is tooth mousse
made from casein
it is milk product to paste on teeth
very common
what does CPP-ACP stand for
Casein phosphopeptide–amorphous calcium phosphate
where do we lose most of the enamel
at the sub surface
what is the conc of fluoride varnish used in clinic
22600 ppm
what do we apply at the surface enamel
high fluoride varnish
