Question 8

How do we distinguish between the three stages of the periodontium?

Answer 8

Charactertistics of the epithelial-connective tissue junction
Position of the junctional epithelium
Position of the crest of the bone

Question 9

Gingivitis/gingival pocket characterisitics

Answer 9

JE at the CEJ
Supragingival fiber destruction

Periodontal ligament intact

Question 10

Gingivitis is chatacterized by its clinical changes of:

Answer 10

Colour
Margin contour
Papilla contour
Consistancy
Bleeding

Question 11

What is a key indicator of the presence of gingivitis?

Answer 11

Bleeding on probing and exploration

Question 12

Gingivitis probing depth

Answer 12

Greater than 3mm

Question 13

What is a pseudo pocket or false pocket?

Answer 13

There is no apical migration of the junctional epithelium

Question 14

What causes increased probing depths of gingival pockets?

Answer 14

Detachment from the coronal portion of the JE from the tooth
Increased tissue size due to swelling of the tissue

Question 15

Periodontal pocket chracteristics

Answer 15

JE on cementum
Supragingival fiber destruction
Alveolar bone destruction
Periodontal ligament destruction

Question 16

Periodontitis is a type of periodontal disease which is characterized by the clinical changes of

Answer 16

Apical migration of the junctional epithelium
Loss of connective tissue attachement
Loss of alveolar bone

Question 17

Periodontitis characteristics

Answer 17

Change in colour
Bleeding on probing or suppuration
Probing depths of 4mm or greater
JE on cementum
Supragingival, alveolar bone, and periodontal ligament destruction

Question 18

In periodontitis extension of the epithelial ridges occur due to

Answer 18

The destruction of gingival fibers which creates space for the epithelium to grow into.

Question 19

In health, the crest of the alveolar bone is located approximately _____ apical to the cementoenamel junction

Answer 19

2mm

Question 20

In periodontitis, the crest of the alveolar bone is located ____ than ____ apical to the cementoenamel junction.

Answer 20

More than 2mm

Question 21

Bone destruction may eventually lead to

Answer 21

Tooth mobility or loss

Question 22

Most common pattern of bone loss is

Answer 22

Horizontal

Question 23

Vertical pattern bone loss results in

Answer 23

A trenchlike area of missing bone alongside the root

Question 24

What is it called when there is a pathological deepening of the sulcus resulting from apical migration of the JE, destruction of the PDL fibers, and destruction of the alveolar bone?

Answer 24

Periodontal pocket

Question 25

What are the two types of peridontal pocket?

Answer 25

Suprabony
Infrabony

Question 26

How is the type of periodontal pocket determined?

Answer 26

Based on the relationship to the JE to the crest of the alveolar bone

Question 27

Which type of periodontal pocket is this?

Answer 27

Suprabony (Horizontal bone loss)

Question 28

Which type of periodontal pocket is this?

Answer 28

Infrabony (Vertical bone loss)

Question 29

What type of periodontal pocket has bone resporption in an uneven, oblique pattern that affects one tooth?

Answer 29

Infrabony

Question 30
