17
Q

Is the bacterial test indicated for low or moderate risk CAMBRA?

A

May be done as reference for new patient. Or for moderate risk if high bacterial challenge is suspected.

18
Q

What is the difference for fluoride recommendation b/w low and medium risk CAMBRA?

A

OTC fluoride twice daily for both, however, for moderate also add fluoride rinse (.05% NaF) daily

19
Q

What is the difference for fluoride recommendation b/w high and extreme risk CAMBRA?

A

Fluoride varnish for both. Extreme = fluoride trays for at home application with Prevident 5000 gel daily 5 minutes

20
Q

What is the recommended frequency of xrays for low and moderate CAMBRA? High? Extreme?

A

BWs every 18-24 months.
High = BWs 6-12 months
Extreme = BWs every 6 months

21
Q

What is the recommended frequency of Periodic Oral Exams (POE) for low and moderate CAMBRA? High? Extreme?

A

Every 12 mths.
High = 6-12 mths and apply fluoride varnish
Extreme = 3-6 mths and apply fluoride varnish

22
Q

What is the recommended frequency of Xylitol/Baking soda for low and moderate CAMBRA? High? Extreme?

A 
Low = none
Moderate = 2 sticks 2x daily
High = 2 sticks 4x daily
Extreme = Baking soda 2 tsp. in 8oz 4-6x daily AND Xylitol 4x daily
23
Q

What is the recommendation regarding sealants for low and moderate CAMBRA? High? Extreme?

A

Low = none

Moderate to Extreme = Sealants for deep pits and fissures

24
Q

DMF indices, what do most studies measure?

A

D2-D4 caries

25
Q

20% of children experience ____% of the decay?

A

80%

26
Q

How long does it take on average for a lesion to progress thru the enamel of permanent teeth?

A

4 years

27
Q

T/F DMFS decreased as sucrose intake decreased b/c of substitution with HFCS

A

T

28
Q

Is there any evidence that removal of plaque by brushing with non-fluoridated toothpaste or flossing reduces the incidence of caries?

A

No evidence

29
Q

T/F Detection of cavitated lesions is no longer an appropriate diagnosis of dental caries

A

T, need system to diagnose BEFORE cavitation

30
Q

What is the advantage of DIFOTI?

A

Can detect incipient or recurring caries before they are visible on xrays

31
Q

T/F Sealing teeth with incipient caries has a higher risk for developing decay.

A

F. Actually teeth sealed even with incipient decay have lower risk of progressing into decay after 5 years according to study

32
Q

Does filling teeth treat the disease of dental caries?

A

No, it simply restores the effects of the disease

33
Q

Does smoking affect CAMBRA risk factors?

A

No

34
Q

Where are PRPs produced? What do they do?

A

Parotid and submandibular saliva.
Form pellicle.
Inhibit spontaneous precipitation of calcium by binding to it

35
Q

What do statherins do?

A

Form pellicle.

Inhibit primary precipitation of Ca and PO4

36
Q

What do histatins do?

A

Form pellicle.
Are antibacterial
Antifungal (Candida albicans)

37
Q

Where are cystatins produced? What do cystatins do?

A

Submandibular/sublingual saliva.

Form pellicle

38
Q

How long does it take for a salivary pellicle to form?

A

Hours to form and days to mature

39
Q

How does fluoride enter the bacterial cell?

A

Must enter as a hydrogen fluoride complex, then F- can interfere with bacterial enzymes

40
Q

What is most effective in reducing colonization of S. mutans?

A

Xylitol>CHX>Fluoride varnish
