2- Periodontology 1

Question 1

What do the periodontal tissues comprise of?

Answer 1

• Gingival Tissues
• Root Cementum
• Periodontal Ligaments
• Alveolar bone

Question 2

Define Gingivitis?

Answer 2

An inflammatory lesion mediated by hist-parasite interaction that remains localised to the gingival tissues and does not extend to involve the periodontal ligament, cementum or alveolar bone

Question 3

Define Periodontitis?

Answer 3

An inflammatory lesion mediated by host-parasite interactions that result in the loss of connective tissue fibre attachment to the root surface and ultimately to alveolar bone loss.

Question 4

What is periodontal attachment formed by?

Answer 4

cementum, periodontal ligament and alveolar bone

Question 5

What is attachment loss?

Answer 5

loss of the normal interactions among cementum, periodontal ligament and alveolar bone due to periodontitis

Question 6

What are the periodontal parameters?

Answer 6

• Pocket depth
• Gingival Recession
• Clinical Attachment Loss
• Bleeding on Probing
• Plaque Index
• Tooth Mobility
• Furcation Involvement

Question 7

What is pocket depth?

Answer 7

Distance between the free gingival margin to the bottom of the sulcus/pocket.

Question 8

What is gingival recession?

Answer 8

Distance between
