Flashcards in Lec 2 Deck (41):
1

proximal lesion on outer half of enamel

e1

2

proximal lesion to inner half of enamel

e2

3

proximal lesion on outer third of dentin

d1

4

proximal lesion on middle third of dentin

d2

5

proximal lesion on inner third of dentin

d3

6

fill teeth and open them up if they are these icdas or these proximals

4,5,6
d2,d3

7

do not open up teeth with these icdas or proximals

0,1,2
E1, E2

8

these icdas or proximals are up to the individual dentist

3, d1

9

determination of how likely patient is to develop new lesions in the near future

caries risk assessment

10

three classifications for caries risk assessment

low, moderate, high

11

three things needed for caries

microflora, host, substrate

12

three criteria of carries risk assessment

disease indicators, risk factors, protective factors

13

any yes circled in this column automatically results in high risk

disease indicators

14

disease indicators

visible cavities or lesions that penetrate into dentin, active proximal lesions, active white spots that are rough, restorations from caries in last 3 years, extractions from caries in last 3 years

15

risk factors column show us how we can blank

prevent new caries

16

risk factors

visible plaque, deep pits/fissures, saliva reducing factors like meds, dry mouth, restorations with overhangs, exposed roots, ortho appliances/partial dentures, infrequent or irregular dental care, frequent snacks, high sugar intake, recreational drug use

17

1 risk factor means blank risk level

moderate sometimes low

18

more than one risk factor means blank risk level

moderate sometimes high

19

mineral component of enamel

hydroxyapatite

20

mechanism of cavity formation

bacteria eat sugar and make acidic plaque that eats away hydroxyapatite

21

pH above 5.5 allows sodium fluoride to assist with blank

remineralization

22

pH between 4.5 and 5.5, sodium fluoride can blank

inhibit demineralization

23

pH below 4.5 sodium fluoride can blank

do nothing

24

protective factors do not change blank

risk level

25

most important protective factor

fluoride

26

blank removes plaque but fluoride protects the tooth

brushing

27

regular toothpaste has this amount of fluoride

1100 ppm

28

prescription prevident colgate toothpaste amount of fluoride

5000 ppm

29

tablets that show plaque and help brushing habits

dislosing tablets

30

fluoride varnish has this much fluoride

22,500 ppm

31

fluoride foam and gel have this much fluoride

gel, foam

32

high risk patients should have fluoride varnish every blank months and blank toothpaste twice a day

3, prescription

33

moderate risk patients should have varnish every blank months and blank toothpaste twice a day

6, otc

34
