fluoride Flashcards
which dental material has the ability to release fluoride
glass ionomer
does fluoride have bactericidal effect? what happens?
fluoride does have bactericidal effect, and it is able to destroy certain types of bacteria
explain the pre-eruptive stage and how fluoride i incorporated
the pre-eruptive stage is when the teeth are developing after birth, but before the teeth erupt
fluoride is deposited during the formation of the enamel, and is in a fluid filled sac, the fluoride in the fluid strengthens the enamel and is from the mothers diet
explain what the post eruptive stage is and how fluoride is incorporated
post eruptive is when the teeth erupt, fluoride is incorporated into the teeth from someones day to day intake whether topical or systemic
what must be done to the teeth prior to any fluoride application
must be dried
what type of filter can be used to remove fluoride from wter
carbon filters
what is fluoriosis and how does it happen
too much fluoride during the developmental stage of the tooth
- occurs from chronic over exposure
can an adult with fully developed and erupted teeth develop fluorosis? why?
no, because their teeth are fully developed
what is enamel hypoplasia
a defect of the enamel that only occurs while teeth are still developing
- white spots, pit and grooves or brown lines
what is the recommended amount of fluoride gel in one tray for an adult
5ml
what is the recommended amount of fluoride gel in one tray for a child
2ml
is fluoride rinse recommended for children adn why
no, children are at risk for swallowing
what would be the most beneficial form of fluoride to place on a childs teeth
varnish
name a food/beverages that have fluoride
water, black tea, wine, grape
what does apf stand for
acidulated phosphate fluoride
what does naf stand for
sodium fluoride
what is the difference between topical and systemic fluoride
systemic: by way of circulation to developing teeth
topical: is applied directly to the exposed surface
what is the primary source of topical fluoride
toothpaste
would tap water be considered a topical or systemic fluoride
it would be considered topical and systemic
when drinking tap water, would the anterior teeth receive more fluoride or posterior
anterior
how is fluoride excreted from the body
fluoride is excreted from the body through the kidneys and sweat glands
which type of fluoride can cause staining
stannous fluoride
what kind of container should APF be stored in
in plastic
what kind of container should naf be stored in
polyethelene
what kind of container should stannous fluoride be stored in
in plastic
what are the post op instructions for someone who has received apf or naf gel fluoride
instruct patient not to rinse, eat, drink or smoke for at least 30 minutes
what are the post op instructions for someone who has received fluoride varnish
patient should avoid brushing teeth for at least 4-6 hours
avoid harad, crunchy and hot foods and beverages
what should be done if a patient accidentally ingests a a large amount of fluoride
give them milk
what is fluorapatite and how is it formed
it is a form of hydorxyapatite where fluorice ions have replaced some hydroxyl ions
it is harder than original tooth surface, it is more resistant to decay and reduces acid production
when would fluoride treatment be indicared
risk assessment for patient
xerostomia
children over 6
newly erupted teeth
after rubber cup polish
what is the halo effect
occurs in increased fluoride intake for people living in non fluoridared communities providing them protection against caries
if a apatient has composite resins, and 2 pbm crowns, which type of fluoride would be recommended
neutral
if a patient has generalized decalcification, which type of fluoride would be recommended for them
varnish
if a patient has no restorations, which type of fluoride would be recommended for them
gel tray type
what is the optimum concentration of water fluoridation
0.7mg/L
optimum levels of water fluoridation depend on what
the climate
what type or types of fluoride do toothpastes generally contain
sodium fluoride
sodium manafluorophophate
stannous fluoride
describe the procedural steps for applying a varnish application on a patient
dispense the varnish
discard any clear varnish
use an applicator brush to mix varnish
apply
what is the pH of NaF
7.0
why is fluoridated toothpaste not recommended for children under 6
they could swallow larger quantities of fluoride
what does ppm stand for
parts per million
what are the indications for mouth rinsese
- areas of demineralization
- root exposure
- moderate or rampant caries
- hypersensitivity
why is fluoride treatment contraindicated prior to palcement of sealants
it minimizes the proper etching before placement of sealants
which type of fluoride decreases dental hypersensitivity
fluoride varnish
what precautions are necessary for children who use fluoridated toothpastes
children should use a pea-seized amount and be supervised while brushing
what are some ways to receive fluoride therapy
consumption, over the counter, dental office
does fluoride contain plaque
there is fluoride in plaque
what does dairy do to fluoride
calcium in dairy makes it harder for the body to absorb fluoride
when should you use gel fluoride
5 minutes before bedtime
how much solution should you use for a mouth rinse
10 ml
are topical fluorides permanent
no
what is done before, fluoride or scaling and polishing
scaling and polishing
what is the percentage of caries reduction for sodium fluoride
40%
what forms of fluoride is stannous fluoride available in
rinse or varnish
what is the percentage of caries reduction for acidulated phosphate
40-50%
what is active intake of fluoride
rapid intake of excess dose over a short time
what is chronic toxicity
long term intake of fluoride
minimum dose of fluoride that can cause fluoride toxicity
5mg/kg
