Flashcards in Lecture 2 Deck (21):
1

strep mutans

good marker for disease but not necessarily the etiological agent of disease

acidogenic (produces acid) and acidouric (thrives in acidic environments)

2

strep sobrinus

1 of primary colonizers; more acidogenic, more acidouric than strep mutans, but strep mutans in in higher concentration taking over colonization

3

potential roadblock on basis of its location

supragingival - above the gingiva; facultative anaerobes

subgingival - below the gingiva; will have more anaerobic bacteria

4

potential roadblock on basis of pathogenicity

cariogenic - generally acidogenic and gram-positive

periopathogenic- mostly basophilic and gram-negative

5

CAMBRA-Caries Management by Risk Assessment

Step 1 - caries risk assessment through:
disease indicators, risk factors, protective factors
Step 2- categorize risk (low? moderate? severe?)
Step 3- determine the associated clinical protocols or interventions (customize plan for every patient)

6

Disease indicators

WREC
white spot lesions, restoration w/in 3 years, enamel lesions, or cavities/dentin

7

risk factors

B- bacteria
A- absence of saliva
D- Diet/lifestyle, destructive lifestyle habits

8

protective factors

S- saliva/sealants
A- antibacterials
F- fluoride/ Ca2+/PO3-4
E - Effective diet Lifestyle Habits
R - Risk-based reassessment

9

What is the difference between detection and diagnosis?

detection = cavity; picking up clues

diagnosis = risk factors; trying to come up with a reason why it's there

10

What are groups at risk?

infants/children

young adults

special needs

11

common meds that cause xerostomia

-tylenol PM (Benadryl)
-bp meds
-antidepressants
-pyschoactive drugs
-muscle relaxants
-alcohol containing mouth rinses
-asthma meds/inhalers

12

Remineralization can only occur in the presence of what?

calcium and phosphate ions

13

What are some other protective factors aside from saliva and fluoride?

chlorhexidine, calcium and phosphate, xylitol

14

fluoride

primary mode is topical

F- accumulation in plaque

F- affect on enzymatic functions challenge the bacteria

15

Describe how risk is categorized

extreme: high plus severe salivary hypofunction

high: any disease indicators, but can be only w/ multiple risk factors

moderate: risk factors present, likely no disease indicators

low: no disease indicators, few risk factors, outweighed by protective factors

16

CRA (age 0-6) contributing conditions

fluoride exposure, sugary foods/drinks, eligible for gov. programs, caries experience of mother/caregiver/siblings, dental home

17

CRA (age 0-6) general health conditions

special health care needs

18

CRA (age 0-6) clinical conditions

restorations/cavitated carious lesions, non-cavitated carious lesions, teeth missing due to caries, visible plaque, dental/orthodontic appliances present (fixed or removable), salivary flow

19

CRA disease indicators

visible cavitations, radiographic lesions, white spot lesions, cavity in last 3 years

20

CRA risk factors

visible plaque, inadequate salivary flow, hyposalivary medications, acidic beverages, frequent snacking (1-3 times a day), appliances present, deep pits and fissures

21

CariScreen testing

saliva sample reads atp of bacteria; low risk 1-1500; high risk 1501-9999
