Q

how does the pH level of the mouth affect fluoride reaction

Study These Flashcards
A

a pH drop in the mouth the fluoride ion will precipitate to a free ion to aid in remineralization

24
Q

how much fluoride should be in the fluoridated water

Study These Flashcards
A

1 ppm (part per million)

25
what do you need to consider when adding fluoride to water
climate daily intake temperature
26
what are carbon filters used for
to filter out any extra fluoride from the water
27
when is systemic fluoride most effective
during the time of tooth development
28
appearance of teeth when the right amount of fluoride is applied
white aging opaque with no blemishes
29
when fluoride is continuously used from birth, what percentage of various lesions are prevented
40-65%
30
what teeth benefit most from drinking fluoridated water
maxillary anterior
31
3 compounds for topical fluoride application
sodium fluoride (NaF) stannous fluoride (SnF) acidulated phosphate fluoride (APF)
32
2.0% Sodium Fluoride (NaF)
has a pH of 7 used for patients with cosmetic dentistry (fillings, crowns, veneers)
33
8% stannous fluoride (SnF2)
pH level is 2.1-2.3 effective for application on root surfaces with early decay and desensitizing cementum can cause brown stains on teeth
34
1.23% acidulated phosphate fluoride (APF)
pH is 3.0-3.5 used for patients with no restos takes 1 min to be done
35
what two fluorides are used most commonly
acidulate phosphate fluoride APF sodium fluoride NaF
36
what type of fluorides is used in toothpaste
sodium fluoride
37
what type of fluoride is prescribed for kids
38% silver diamond fluoride (SDF)
38
fluoride varnish
most commonly used safe easy and has the best retention
39
self applied fluoride
used at home by adults only should not be used on children
40
fluoride toxicity
comes from swallowing fluoride
41
6 symptoms of fluoride toxicity
nausea vomiting diarrhea abdominal pain increased salivation thirst
42
what is the amount of fluoride uptake determined by
amount ingested when it was ingested length and time of exposure
43
fluoride toxicity effects on bone
bonds with calcium and cause hypocalcemia
44
fluoride toxicity effects on central nervous system
- hyperreflexia - convulsions - parasthesis
45
fluoride toxicity effects on cardiovascular and respiratory
can lead to death
46
acute fluoride poisoning
rapid amount in a small amount of time
47
chronic fluoride poisoning
small amounts over a long period of time can cause fluorosis
48
6 classifications of fluorosis
normal questionable very mild mild moderate severe
49
normal fluorosis
enamel is smooth pale creamy white translucent no fluorosis present
50
questionable fluorosis
a few white spots are seen on the enamel
51
very mild fluorosis
small opaque paper white areas that cover less than 25% of the tooth surface
52
mild fluorosis
opaque areas covering more than 50% of the tooth surface
53
moderate fluorosis
all tooth surfaces are affected possible brown stain
54
severe fluorosis
all tooth surfaces are affected, discrete of confluent pitting, brown stain present
55
post op instructions for fluoride application
no eating drinking or rinsing for 30 mins
