Q

3 steps in remineralization

A
  1. tooth is attacked by acids in plaque and saliva
  2. calcium and phosphate dissolve from the enamel in the process of demineralization
  3. fluoride, phosphate, and calcium re-enter the enamel in a process called remineralization

Q

what are the significant 7 microorganisms associated with biofilm

A
  1. streptococci mutans
  2. streptococci sobrinus
  3. streptococci sanguis
  4. streptococci mitis
  5. streptococci salivarius
  6. lactobacilli
  7. actinomyces
17
Q

characteristics of stretpococci mutans (gram, where is it found, etc)

A
  • 1st main microorganism found in caries
  • gram positive
  • found in large numbers over smooth carious lesions
  • not found in the mouth of babies
  • decrease in numbers as teeth are lost
  • aciduric
18
Q

characteristics of streptococci sobrinus

A
  • gram positive
  • found in mouth of infants
  • settles on pits and fissures
19
Q

characteristics of streptococci sanguis

A
  • gram positive
  • nonmotile
  • found in dental plaque of healthy persons
20
Q

characteristics of streptococci mitis

A
  • gram positive
  • nonmotile
  • can break down in RBC
21
Q

characteristics of streptococci salivarius

A
  • gram positive
  • first bacterium which colonizes dental plaque
  • linked to mouth odor
22
Q

characteristics of lactobacilli

A
  • gram positive
  • found in deeper lesions
  • metabolically 7 active at pH of 5.0
  • cannot initiate caries process
  • acidogenic and aciduric
23
Q

characteristics of actinomyces

A
  • gram positive
  • can be anerobic or facultive anerobic
  • associated with root caries
24
Q

what is the main substance for cariogenic bacteria

A

sucrose

25
Q

Do starches have a low or high cariogenic activity?

A

low

26
Q

when does acid formation begin once a cariogenic substance is taken into biofilm

A

immediately

27
Q

once biofilm has attached to the tooth surface and the pH level drops, if left undisturbed, it will take how long for the pH to return to normal?

A

1-2 hours

28
Q

if food or a cariogenic substance has not occured, pH levels are what?

A

6.2-7.0

29
Q

is the pH lower or higher than 6.2-7.0 in high risk caries patients?

A

the range is lower

30
Q

at what pH does enamel demineralization begin at?

A

4.5-5.5

31
Q

is the root surface of a tooth softer or harder which makes it more porous than enamel?

A

softer which makes it break down faster

32
Q

the amount of demineralization is directly related to the amount of time the ____ has had an opportunity to be on the tooth surface

A

acid

33
Q

should a DH recommend drinking soda through-out the day or in one sitting?

A

one sitting

34
Q

what can we do to decrease biofilm?

A
  • brushing/flossing
  • increase fluoride exposure
  • implementation of sealant placement
  • decrease sugar foods and increase detergent foods
  • establish a recall
35
Q

what is the sequence of caries process?

A
  1. cariogenic foods
  2. dental biofilm
  3. acid formation
  4. demineralization
  5. dental caries
36
Q

what is the primary role to prevent the disease process of caries from progressing

A

educate patients to prevent the disease process
