Flashcards in Perio Ch 3&6 Quiz 1 Deck (27):
1

_____ deals with the events that occur during the development of the periodontal disease

Periodontology

2

Is gingivitis reversible?

Yes

3

Is periodontitis reversible?

No

4

2 types of periodontal disease?

Gingivitis
Periodontitis

5

Difference between periodontitis and periodontal disease?

Periodontitis is a type of periodontal disease

6

When can gingivitis be observed clinically?

From 4-14 days after plaque biofilm accumulates in sulcus

7

Acute gingivitis

Short period of time

Sulcus depth over 3mm due to tissue enlargement

Papillae: bulbous and swollen

JE remains normal

8

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

9

Can gingivitis persist for years without progressing to periodontitis?

Yes

10

What is periodontitis?

A type of periodontal disease.

-apical migration of the JE

- loss of connective tissue attachment

-loss of alveolar bone

11

Which periodontal disease has apical migration of the junctional epithelium?

Periodontitis

12

Where is the alveolar crest located in health and gingivitis?

2mm apical to the CEJs

13

What type of bone loss leaves a trench like area of missing bone alongside the root

Vertical bone loss

14

What is a pocket?

-A diseased sulcus
-Presence or absence of infection that distinguishes a pocket from a sulcus

15

What is a false pocket?

Pseudopocket

16

What are the 2 types of pockets?

Gingival pocket
Periodontal pocket

17

How do you distinguish between a gingival pocket and a periodontal pocket?

Level of attachment

18

The sequence of events that occur during the development of a disease or abnormal condition is?

Pathogenesis

19

Suprabony pockets are seen when?

There is horizontal bone loss

JE is located coronal to the crest of the alveolar bone

20

Infrabony pockets are seen when?

There is vertical bone loss

21

A bowl shaped defect in the interdental alveolar bone win bone loss nearly equal on the roots of 2 adjacent teeth

Interproximal Osseous crater

22

What is attachment loss?

Destruction of the fibers and alveolar bone that support the teeth

23

Active disease site shows what?

Continued apical migration of the JE over time

24

Inactive disease site shows what?

Attachment level of the JE remain at the same level for a period of time

25

Do gingival pockets have destruction of PDL fibers or alveolar bone?

No

26

Do periodontal pockets have destruction of PDL fibers or alveolar bone?

Yes

27

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
