Flashcards in Chronic Periodontitis Deck (50):
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!
What are five clinical features of Chronic Periodontitis?
1. Changes in gingival morphology
3. Increased probing depths
4. Attachment Loss
5. Gingival Recession apical to the CEJ
True or False: Probe depths are similar to attachment loss.
False: they are not interchangeable!
Alveolar bone loss associated with chronic periodontitis is either ______ or ______.
Vertical or horizontal
_____ involvement is variable due to root morphology differences.
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
Tissue destruction in chronic periodontitis corresponds with oral hygiene, _____ levels, and ______ factors
oral or systemic
True or False: Subgingival calculus is invariably present at disease sites.
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
Rate of progression is ____ to moderate and rapid bursts of destruction _____ occur.
rapid bursts CAN occur
In chronic periodontitis, what determines pathogenesis and progression?
Which sites on the periodontium are more likely to sustain further breakdown?
untreated diseased sites
True or False: The best predictor for future attachment or bone loss is past attachment or bone loss.
Once there are clinical signs of attachment loss, how long until bone loss occurs?
Why is early diagnosis of chronic periodontitis so difficult?
because it is mostly painless
What kind of pain symptoms are generally associated with chronic periodontitis?
-Localized dull pain
-Gingival tenderness, ‘itching’ gums
The "extent" of chronic periodontitis is classified as either _____ or _______.
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
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
Is "generalized slight with localized moderate chronic periodontitis" a possible diagnosis?
Is "generalized gingivitis with localized severe chronic periodontitis" a possible diagnosis?
No, once attachment loss occurs....gingivitis goes out the window
True or False: Smoking has a greater impact on formation of periodontal pockets in the young.
ages 21-40: non-smokers = 10 --> smokers = 30
ages 41-60: non-smokers = 30--> smokers = 40
Risk determinants are ______ factors.
Risk ______ have been identified in cross-sectional studies but have not been confirmed longitudinally.
("IN the name of the cross" -->indicators = cross sectional)
HIV/AIDS, osteoporosis, and infrequent dental visits are all risk ______.
Risk ______ are associated with elevated risk but may not be part of the CAUSE.
ex: furcation involvement, previous perio, calculus
True or False: All gingivitis will eventually lead to periodontitis.
True or False: Gingivitis can be stable for years.
Bacterial _____ induces gingivitis, but _______ determines if chronic periodontitis will develop.
True or False: Absence of gingivitis is not a good indicator of future periodontal health.
False, its a good indicator of future health
_____% of the US population has periodontitis ~65 million people.
How is chronic periodontitis associated with gender?
it is HIGHER in men
_____% of adults above 65 years old have moderate or severe periodontitis.
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
What are the three models of periodontitis progression?
1. Continuous Model
2. Random Burst Model
3. Asynchronous Multiple Burst Model
Which model of progression shows a "slow and constant rate?"
Which model of progression is not specific in its time or site of destruction?
Random Burst Model
Which model of progression is more highly associated with Aggressive Perio?
Asynchronous Multiple Burst Model (destruction during specific time frames of life)
Clinical Attachment Loss = _____ + ______
probing depth + gingival recession
How is BoP expressed?
as % of total sites AVAILABLE
What is fremitis?
mobility of tooth upon occlusion
What are the four deconfiguration patterns of bony defects?
1 wall, 2 wall, 3 wall, or circumferential
(pattern is critical to treatment)
True or False: Treatment of chronic periodontitis is effective and limits tooth loss to 0.6mm teeth/year.
True or False: Untreated patients lost approximately 0.6 teeth/year.
Non-compliant patients had _____ the rate of tooth loss per year.
double (0.2 instead of 0.1 in the compliant group)
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"
Which sites are most susceptible to trauma from digging out pockets?
buccal sites with thin tissue type
______ = probe depths less than 2.9mm = root planing at this depth will cause attachment loss
Critical Probe Depth
True or False: Although periodontal disease is not reversible, you can increase the appearance, decrease inflammation, and decrease redness.
