16
Q

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

A

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

17
Q

Periodontitis characteristics

A

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

18
Q

In periodontitis extension of the epithelial ridges occur due to

A

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

19
Q

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

A

2mm

20
Q

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

A

More than 2mm

21
Q

Bone destruction may eventually lead to

A

Tooth mobility or loss

22
Q

Most common pattern of bone loss is

A

Horizontal

23
Q

Vertical pattern bone loss results in

A

A trenchlike area of missing bone alongside the root

24
Q

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?

A

Periodontal pocket

25
Q

What are the two types of peridontal pocket?

A

Suprabony
Infrabony

26
Q

How is the type of periodontal pocket determined?

A

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

27
Q

Which type of periodontal pocket is this?

A

Suprabony (Horizontal bone loss)

28
Q

Which type of periodontal pocket is this?

A

Infrabony (Vertical bone loss)

29
Q

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

A

Infrabony

30
Q

What is this diagram showing?

A

One-wall infrabony defect

31
Q

What is this diagram showing?

A

Two-wall infrabony defect

32
Q

What is this diagram showing?
