DHT 141 Fluoride Week 12 Questions and
Correct Answers. 100% Correct. 2024/2025.
in what routes are fluoride available?
they are Available to the tooth by a topical and Systemic route
when is systemic fluoride the most effective?
Systemic fluoride is most effective from birth - 14 years of age
what was the recommendation for the serving of fluoride per day in 2015
2015 recommendation is 0.7 mg/L (1PPM = 1mg F /liter of H2O) community water system
where can fluoride be found naturally
fluoride can be found in foods such as fish, tea, fruit
what form is fluoride available in?
tablets and drops
how well does fluoride act in reducing caries?
fluoride reduces caries rate by up to 50%
where is fluoride absorbed?
fluoride is absorbed in the stomach and small intestines
when does the peak absorbance of fluoride occur?
the peak level is reached in 1 hour
Do you think that given where fluoride is found in food and beverages that certain ethnicities would have
less decay?
yes.
Low urinary PH is associated with a
low fluoride excretion
Increase urinary PH is associated with
high fluoride excretion
does prenatal fluoride cross the placenta?
Prenatal fluoride does cross placenta but it does not reduce caries in offspring so it is not recommended
what is the concentration of fluoride in breast milk?
,Breast milk has low fluoride
how much fluoride is in baby formula?
Baby formula fluoride levels are low, but reconstituted may have levels of fluoride due to water used to
mix with the powder
do water filtration systems remove fluoride from water?
Yes. Some water filtration systems remove fluoride from the water
Is the amount of fluoride in bottled water listed on the label?
The FDA doesn't require bottlers to list the fluoride content in a bottle of water
However, the FDA does require fluoride additives to be listed.
How can I find out the level of fluoride in bottled water?
contact the manufacturer and ask about the fluoride content of a particular brand of bottled water.
an increased amount of fluoride will increase the
resistance to acid attacks by reducing enamel solubility;
producing an anti-caries effect
where does the fluoride go?
the fluoride is absorbed by the tooth's enamel with calcium and phosphate
how does fluoride doses work?
the fluoride is effective at re-mineralization because it prefers to go to the de-mineralized enamel over
the sound enamel
it helps by modifying crystal size within an enamel lesion to re-mineralize it
Fluoride in low concentration and high frequency increases the rate of
the growth and size of crystals that are formed
what types of crystals are less likely to be damaged by acid attacks?
larger crystals are more resistant to acid attacks
True or false does fluoride have an anti-bacterial effect?
yes.
this is true fluoride has an anti-bacterial effect
True or false does fluoride have a de-sensitizing effect?
, true fluoride has a de-sensitizing effect
how does fluoride have an anti-bacterial affect?
the fluoride interferes with the metabolism of bacteria
for example, the conversion of glucose to lactic acid
it reduces energy making bacterial attachment to the tooth's enamel more difficult
stannous fluoride aka SnF
Stannous Fluoride has more antibacterial effects than NaF because of the associated accumulation of tin
inside bacteria espesially S. Mutans
how does fluoride work as a de-sensitizing agent?
because fluoride reduces sensitivity by mechanically blocking dentinal tubules with fluorapatite
what patients are great for the de-sensitizing uses of fluoride treatment
fluoride is effective for Clients with Special Needs, xerostomia, radiation, etc.
how much fluoride does plaque contain?
Plaque contains 5-50 PPM fluoride.
what supplies the fluoride to the plaque?
Saliva & crevicular fluid supply fluoride to plaque
why is it beneficial to have fluoride in plaque?
Fluoride is beneficial to have within plaque because it inhibits acid production in plaque.
True or false fluoride lowers the metabolism of plaque
True. Fluoride lowers the metabolism of plaque.
True or false fluoride inhibits carb metabolism
true. Fluoride inhibits carbohydrate metabolism.
does fluoride reduce or increase the ability of plaque to adhere to the tooth
Fluoride reduces ability of plaque to adhere to tooth.
does fluoride affect the cariogenic potential of plaque?
yes. Fluoride reduces the cariogenic potential of plaque.
