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

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
What are the two types of peridontal pocket?
Suprabony Infrabony
26
How is the type of periodontal pocket determined?
Based on the relationship to the JE to the crest of the alveolar bone
27
Which type of periodontal pocket is this?
Suprabony (Horizontal bone loss)
28
Which type of periodontal pocket is this?
Infrabony (Vertical bone loss)
29
What type of periodontal pocket has bone resporption in an uneven, oblique pattern that affects one tooth?
Infrabony
30
What is this diagram showing?
One-wall infrabony defect
31
What is this diagram showing?
Two-wall infrabony defect
32
What is this diagram showing?
Three-wall infrabony defect
33
What is it called when a contour of bone from the facial to the lingual dips apically forming a bowl-shaped crater which affects two adjacent root surfaces?
Osseous Crater
34
What are the furcation involvement classes?
1 2 3 4
