Flashcards in chronic periodontitis Deck (36):
1

T/F: chronic periodontitis is most prevalent in adults, but may be seen in children

true

2

in chronic perio, Tissue destruction is commensurate with what?

oral hygiene & plaque levels and local/systemic factors

3

T/F: Specific subgingival species are found in all patients suffering from chronic periodontitis

false

individual species vary among individuals

4

Subgingival ________ is invariably present at disease sites

calculus

5

the rate of progression of chronic periodontitis is _____ to _______

slow to moderate

6

what determines pathogenesis and progression of chronic perio?

Host factors

7

what type of pain is associated with chronic periodontitis?

*Mostly painless

Localized dull pain
Gingival tenderness, ‘itching’ gums

8

what are the symptoms of chronic periodontitis?

Loose teeth
Food impaction
Drifted teeth/ increased spacing
Root sensitivity
Bleeding gums

9

localized chronic periodontitis occurs at _____% of sites, while generalized will occur at ______%

localized- ≤30% of sites

generalized- >30% of sites

10

what is the difference between slight, moderate and severe chronic perio?

Slight: 1-2 mm of attachment loss

moderate: 3-4 mm of loss

severe: 5 mm or more

11

what is the "typical diagnosis" of chronic perio?

Generalized slight with localized moderate chronic periodontitis

12

T/F: most cases of chronic periodontitis can be seen by a visual examination

FALSE

probing must be used to determine attachment loss

13

what % of the population is at high risk for chronic perio? low risk?

10% of population is at high risk

10% is at low risk

(most people fall somewhere in between)

14

what 2 risk factors can be modified with intervention?

Smoking

Diabetes

15

what is a risk determinant? give an example of one

Risk determinant: non-modifiable factors

age
gender

16

what is a risk indicator? name them.

putative risk factors that have been identified in cross sectional studies but not confirmed longitudinally

HIV/AIDS
Osteoporosis
Infrequent dental visits

17

what are Risk markers/predictors? give examples.

a characteristic associated with elevated risk for disease but may not be part of the causal chain

Furcation involvement
Calculus
History of attachment loss

18

_________ _______ induces gingivitis, but host response determines if Chronic periodontitis will develop

bacterial plaque

19

what did the chinese studies find about the relation between gingivitis and CP?

gingival inflammation a risk for Attachment Loss at any site

20

what did the norwegian studies find about the relation between gingivitis and CP?

tooth loss greater in sites with baseline severe gingival inflammation

21

approximately _____% of americans are affected by ADVANCED periodontal disease (according to the NIDR study)

13%

22

_____% of US population has periodontitis. how many people is this?

>47%

over 65 million people

23

what % of the population has mild periodontitis? moderate? severe? (according to the NHANES study)

8.7% mild periodontitis
30% moderate periodontitis
8.5 % severe periodontitis

24

T/F: 64% of adults over 65 years old had either moderate or severe periodontitis

true

25

what population groups are at the highest risk for periodontitis?

Prevalence highest in:

men

Mexican Americans

adults with less than a high school education

adults below 100% Federal Poverty Levels

current smokers.

26

_________ Periodontitis is the 6th most prevalent disease in the world

severe

27

what is a "cal" equal to?

probing depth + gingival recession

28

what recordings are taken in the diagnosis of periodontitis?

Probing Depth
Gingival Recession
CAL
BOP (expressed as % of total sites available)
Furcation involvement
Mobility
Fremitus
Bone defects

29

what type of bone defects are relevant to the diagnosis of periodontitis?

Horizontal vs. vertical

1-wall, 2-wall, 3-wall bony defects.

30

what are the goals of therapy for periodontitis?

Eliminate etiology
Eliminate or reduce risk factors
Prevent recurrence

31

name the steps involved in initial periodontal therapy:

Removal of both sub and supragingival plaque
Adequate oral hygiene
Remove local and systemic risk factors

32

what is the "rationale" for periodontal treatment? (AKA how do we know it works?)

Periodontal treatment of CP is effective (<0.1 tooth loss/year)

Non-compliant patients had double the rate of tooth loss (0.2 teeth/year)

Untreated patients lost approximately 0.6 teeth/year

33

what causes the reduction in probing depths after INITIAL perio therapy?

gingival recession

gain of clinical attachment

pocket shrinkage

34

T/F: after initial therapy, sites with initially shallow pockets tend to lose CAL (possible trauma)

true

35

when would a patient be at a greater risk for additional attachment loss as a result of therapy?

if presenting multiple sites with residual probing depth >6 mm after active treatment

36

T/F: it is possible to maintain a 6mm pocket during periodontitis therapy if the proper precautions are taken

FALSE

You cannot maintain 6 mm pockets- surgical therapy recommended
