Flashcards in Chronic Periodontitis Deck (50):
1

True or False: Chronic periodontitis should always be obvious upon inspecting the mouth due to inflammation and bleeding.

False, it's not always obvious just by looking!

2

What are five clinical features of Chronic Periodontitis?

1. Changes in gingival morphology
2. BoP
3. Increased probing depths
4. Attachment Loss
5. Gingival Recession apical to the CEJ

3

True or False: Probe depths are similar to attachment loss.

False: they are not interchangeable!

4

Alveolar bone loss associated with chronic periodontitis is either ______ or ______.

Vertical or horizontal

5

_____ involvement is variable due to root morphology differences.

Furcation

6

True or False: Decreased tooth mobility, ankylosed teeth, and tooth loss are all associated with chronic periodontitis.

False: INCREASED tooth mobility, drifting teeth, and tooth loss are associated

7

Tissue destruction in chronic periodontitis corresponds with oral hygiene, _____ levels, and ______ factors

plaque levels
oral or systemic

8

True or False: Subgingival calculus is invariably present at disease sites.

True

9

True or False: Individual species vary among individuals and specific subgingival species are not implicated in disease.

False. There is individual variation but specific species ARE implicated

10

Rate of progression is ____ to moderate and rapid bursts of destruction _____ occur.

Slow progression
rapid bursts CAN occur

11

In chronic periodontitis, what determines pathogenesis and progression?

host factors

12

Which sites on the periodontium are more likely to sustain further breakdown?

untreated diseased sites

13

True or False: The best predictor for future attachment or bone loss is past attachment or bone loss.

True

14

Once there are clinical signs of attachment loss, how long until bone loss occurs?

six months

15

Why is early diagnosis of chronic periodontitis so difficult?

because it is mostly painless

16

What kind of pain symptoms are generally associated with chronic periodontitis?

-Localized dull pain
-Gingival tenderness, ‘itching’ gums

17

The "extent" of chronic periodontitis is classified as either _____ or _______.

localized
generalized

18

How is localized differentiated from generalized chronic periodontitis?

localized is LESS THAN OR EQUAL to 30% of sites
generalized is GREATER than 30% of sites

19

How is "severity" of chronic periodontitis determined?

By the amount of attachment loss:
1-2 mm = slight
3-4 mm = moderate
5 or more mm = severe

20

Is "generalized slight with localized moderate chronic periodontitis" a possible diagnosis?

yes

21

Is "generalized gingivitis with localized severe chronic periodontitis" a possible diagnosis?

No, once attachment loss occurs....gingivitis goes out the window

22

True or False: Smoking has a greater impact on formation of periodontal pockets in the young.

True
ages 21-40: non-smokers = 10 --> smokers = 30
ages 41-60: non-smokers = 30--> smokers = 40

23

Risk determinants are ______ factors.

non-modifiable

24

Risk ______ have been identified in cross-sectional studies but have not been confirmed longitudinally.

indicators
("IN the name of the cross" -->indicators = cross sectional)

25

HIV/AIDS, osteoporosis, and infrequent dental visits are all risk ______.

indicators

26

Risk ______ are associated with elevated risk but may not be part of the CAUSE.

markers/predictors
ex: furcation involvement, previous perio, calculus

27

True or False: All gingivitis will eventually lead to periodontitis.

False

28

True or False: Gingivitis can be stable for years.

True

29

Bacterial _____ induces gingivitis, but _______ determines if chronic periodontitis will develop.

plaque
host response

30

True or False: Absence of gingivitis is not a good indicator of future periodontal health.

False, its a good indicator of future health

31

_____% of the US population has periodontitis ~65 million people.

>47 %

32

How is chronic periodontitis associated with gender?

it is HIGHER in men

33

_____% of adults above 65 years old have moderate or severe periodontitis.

64%

34

True or False: Severe periodontal disease is the 2nd most prevalent disease in the world.

False. It is the SIXTH most prevalent in the world

35

What are the three models of periodontitis progression?

1. Continuous Model
2. Random Burst Model
3. Asynchronous Multiple Burst Model

36

Which model of progression shows a "slow and constant rate?"

Continuous Model

37

Which model of progression is not specific in its time or site of destruction?

Random Burst Model

38

Which model of progression is more highly associated with Aggressive Perio?

Asynchronous Multiple Burst Model (destruction during specific time frames of life)

39

Clinical Attachment Loss = _____ + ______

probing depth + gingival recession

40

How is BoP expressed?

as % of total sites AVAILABLE

41

What is fremitis?

mobility of tooth upon occlusion

42

What are the four deconfiguration patterns of bony defects?

1 wall, 2 wall, 3 wall, or circumferential
(pattern is critical to treatment)

43

True or False: Treatment of chronic periodontitis is effective and limits tooth loss to 0.6mm teeth/year.

False

44

True or False: Untreated patients lost approximately 0.6 teeth/year.

True

45

Non-compliant patients had _____ the rate of tooth loss per year.

double (0.2 instead of 0.1 in the compliant group)

46

Why do periodontal sites with initially shallow pockets tend to lose CAL?

possible trauma... DO NOT DIG! especially if its of "critical probe depth..2.9mm"

47

Which sites are most susceptible to trauma from digging out pockets?

buccal sites with thin tissue type

48

______ = probe depths less than 2.9mm = root planing at this depth will cause attachment loss

Critical Probe Depth

49

True or False: Although periodontal disease is not reversible, you can increase the appearance, decrease inflammation, and decrease redness.

True

50

You should not maintain (ScRP treatment) _____ mm pockets; surgical therapy is recommended in this circumstance.
