caries symposium Flashcards
1
Q
what is included in a caries risk assessment
A
- MH
-clinical evidence - diet
-social history
-fluoride use
-plaque control
-saliva
2
Q
what is needed for caries
A
-tooth
-substrate (OH, food)
- flora
- plaque
3
Q
what would class someones caries experience as high risk
A
- DMFT >5
-caries in 6’s at 6
3 year caries increment >3
4
Q
what would class someones diet as high risk
A
> 3 sugar intakes a day
-higher frequency more of an issue
5
Q
action of fluoride
A
- incorporation into enamel crystal to form flurorapitite which is more caries resistant (resistant to demineralisation) than hydroxyapatite
- bacteriocidal? resistant streptococcal strains
- interferes with the adhesion force of bacteria reducing their ability to stick to the surface of the teeth
6
Q
role of saliva
A
- amount
-flow
-buffering capacity
-pH
-viscosity
7
Q
8 elements of preventative programme
A
- radiographs
- toothbrushing instruction
- strength of F in toothpaste
- F varnish
- F supplementation
- diet advice
- fissure sealants
- sugar free medicine
8
Q
how often are bitewings carried out
A
6 months for high risk
12-18 for low risk
9
Q
how to identify caries
A
- clinical exam
-probe
-radiograph (bitewing) - temp tooth separation
- FOTI
