Cario Class 5 Flashcards
Is topical or systemic fluoride more effective at caries prevention?
Topical
What are 4 big functions of replacing the hydroxyl group with the fluoride ion in hydroxyapatite (which becomes fluoroapatite)?
- Improves crystal structure (Fluoride is strongly bonded to the lattice site)
- Decreases solubility (more stable apatite)
- Inhibits bacterial growth
- Promotes remineralization of the enamel
What are two negatives of stannous floride and the positive aspect?
Extrinsic stains and unpleasant taste
+ reduces tooth sensitivity
Acidulated phosphate fluoride: One positive and one negative
- enamel uptake is greatest in acidic environment (pH of 3.0)
+Non-irritating and non-staining
Sodium fluoride: 3 positives and one negative
+ stable, absorbed by enamel at pH 7.0, no staining
- reduces salivary flow
Silver diamine fluoride: 2 positives and 2 negatives
+ lots of fluoride (>44K ppm), arrests carious lesions
-stains carious lesions black, may cause mild gastric inflammation
What evidence is there for fluoride foams?
No “sound” evidence
When was SD approved by the FDA?
2016
When was fluoride varnish approved by the FDA?
1994
What is one benefit and one drawback to fluoride varnish?
+ it slows progression of carious lesions in both permanent and primary teeth
-less longevity than sealants
For how long does one apply fluoride?
4 minutes
What does the “D/d” in DMFT/dmft not include?
Filled teeth
Why did women used to have higher rates of caries prior to water fluoridation?
Their teeth erupt earlier, thus prolonging their exposure to cariogenic challenges
For children 2-19, which group has the highest proportion of untreated caries?
6-11 y/o
For children 2-19, which group has the highest caries experience?
12-19 y/o
Between 9-11 y/o and 6-8 y/o, which group has more sealants?
9-11 >6-8
For adolescents 2-19, what ethnicity has the greatest total caries experience?
H>B>W
For adolescents 2-19, which group has the most untreated caries?
B>H>W
For adults age 20-64, which which group has the greatest total caries experience?
W>B/H
For adults age 20-64, which group has the most untreated caries?
B>H>W
For adults 65+, which group has the greatest total caries experience?
W>B/H
For adults 65+, which group has the greatest amount of untreated caries?
B>H>W
For adults 65+, who has the greatest number of dental sealants?
W>H>B
For adults 65+, who has the greatest permanent retention?
W>H>B
For adults 65+, which group has the greatest edentulism?
B>W>H
What are three indications to use SDF?
- High risk patients
- Severe ECC
- Multiple lesions
