Perio Ch 3&6 Quiz 1 Flashcards
_____ deals with the events that occur during the development of the periodontal disease
Periodontology
Is gingivitis reversible?
Yes
Is periodontitis reversible?
No
2 types of periodontal disease?
Gingivitis
Periodontitis
Difference between periodontitis and periodontal disease?
Periodontitis is a type of periodontal disease
When can gingivitis be observed clinically?
From 4-14 days after plaque biofilm accumulates in sulcus
Acute gingivitis
Short period of time
Sulcus depth over 3mm due to tissue enlargement
Papillae: bulbous and swollen
JE remains normal
Chronic gingivitis
Last for months or years
Leathery consistency
Bluefish red or pale white
Papillae: blunted or cratered
Excess collagen fibers conceal the redness in the tissue
Can gingivitis persist for years without progressing to periodontitis?
Yes
What is periodontitis?
A type of periodontal disease.
- apical migration of the JE
- loss of connective tissue attachment
- loss of alveolar bone
Which periodontal disease has apical migration of the junctional epithelium?
Periodontitis
Where is the alveolar crest located in health and gingivitis?
2mm apical to the CEJs
What type of bone loss leaves a trench like area of missing bone alongside the root
Vertical bone loss
What is a pocket?
- A diseased sulcus
- Presence or absence of infection that distinguishes a pocket from a sulcus
What is a false pocket?
Pseudopocket
What are the 2 types of pockets?
Gingival pocket
Periodontal pocket
How do you distinguish between a gingival pocket and a periodontal pocket?
Level of attachment
The sequence of events that occur during the development of a disease or abnormal condition is?
Pathogenesis
Suprabony pockets are seen when?
There is horizontal bone loss
JE is located coronal to the crest of the alveolar bone
Infrabony pockets are seen when?
There is vertical bone loss
A bowl shaped defect in the interdental alveolar bone win bone loss nearly equal on the roots of 2 adjacent teeth
Interproximal Osseous crater
What is attachment loss?
Destruction of the fibers and alveolar bone that support the teeth
Active disease site shows what?
Continued apical migration of the JE over time
Inactive disease site shows what?
Attachment level of the JE remain at the same level for a period of time
Do gingival pockets have destruction of PDL fibers or alveolar bone?
No
Do periodontal pockets have destruction of PDL fibers or alveolar bone?
Yes
Can a pocket alone say whether the infection is active or inactive?
No, you will have to check depths in a few months to compare
