Q

another word for demineralization

A

decalcification

20
Q

term for when minerals flow back into enamel and repair micro-concavities formed from demineralization

A

remineralization

21
Q

clinical appearance of an incipient lesion; what is this caused by?

A

rough, white; demineralization

22
Q

clinical appearance of an arrested lesion; what is this caused by?

A

smooth, white; remineralization

23
Q

classification categories for caries

A

by location, by occurence/reoccurence

24
Q

types of caries by location

A

pits/fissures (occlusal), proximal (mesial/distal), smooth surface (Fa/Li)

25
Q

how to see proximal incipient caries

A

look on radiographs

26
Q

how to see smooth surface incipient caries

A

look for decalcification

27
Q

types of caries by occurence/reoccurence

A

incipient, primary, recurrent/secondary caries, rampant caries

28
Q

what defines rampant caries?

A

10 or more caries in span of 1 year

29
Q

tips for identifying caries

A

chalky white, grey halo, yellow-brown (open caries), dullness/loss of translucency, dark shadows in transillumination

30
Q

benefits of fluoride in terms of mechanism of action

A

increased enamel resistance, remineralization of enamel, antibacterial

31
Q

how does fluoride work as an antibacterial?

A

bactericidal (kills in high concentrations), interferes with colonization, interferes with ability to produce acid

32
Q

how do sealants prevent caries?

A

fill pits/fissures to prevent build up of caries-causing bacteria

33
Q

fluoride that goes through body and affects teeth as they are developing

A

systemic fluoride

34
Q

fluoride that is placed topically on teeth, then spit out (not meant to be swallowed), protect erupted teeth

A

topical fluoride

35
Q

methods to deliver systemic fluoride

A

community water fluoridation, dietary supplements

36
Q

diet counseling in relation to caries prevention includes addressing…

A

nutritional value of food, frequency of ingestion, form of food, length of time in mouth

37
Q

two aspects of plaque control in relation to caries prevention

A

Negligible effect on actual caries reductions in research; positive effect on gingival health

38
Q

optimal level of water fluoridation

A

0.7-1.2 ppm

39
Q

benefits of water fluoridation

A

least expensive, most effective, 30-40% reduction of caries, safe, equitable

40
Q

benefits of dietary fluoride supplements

A

well-water tested, 30-40% reduction of cares

41
Q

examples of self-applied topical fluoride treatments; what is the concentration?

A

toothpastes, gels rinses; 1000-1200 ppm

42
Q

examples of professionally-applied topical fluoride treatments; what is the concentration?

A

tray; 12,000 ppm // fluoride varnish; as high as 22,600 ppm

43
Q

overall recommendation for fluoride treatments

A

1 systemic source + topicals

44
Q

ranking of methods to prevent caries

A

sealants > fluoride > nutrition > plaque control

45
Q

periods in which fluoride application is most beneficial

A

calcification (pre-eruptive), maturation (pre-eruptive), immediately post-eruptive, as needed based on risk assessment
