Question 1

What is the first step in managing Miller Class III recession with <2 mm attached gingiva and thin biotype?

Answer 1

Perform a Free Gingival Graft (FGG) to increase the zone of attached gingiva before root coverage.

Question 2

Which factor is most critical in selecting a root coverage technique?

Answer 2

Amount of keratinized tissue apical or lateral to the recession.

Question 3

What is the main esthetic disadvantage of Free Gingival Graft (FGG)?

Answer 3

Color mismatch with adjacent tissue due to lighter appearance of graft.

Question 4

Miller Class II recession is defined by?

Answer 4

Recession extending beyond mucogingival junction without interdental bone or soft tissue loss.

Question 5

Cairo RT3 classification is characterized by?

Answer 5

Interproximal attachment loss greater than buccal attachment loss.

Question 6

Why is connective tissue from beneath keratinized epithelium used for grafting?

Answer 6

It carries the genetic signal for keratinization of the overlying epithelium.

Question 7

When is a subepithelial connective tissue graft (Langer technique) indicated?

Answer 7

For wide and multiple recession defects with good vestibular depth and gingival thickness.

Question 8

True or False: Resorbable membranes used in GTR always require a second surgery.

Answer 8

False. Resorbable membranes do not require removal, unlike non-resorbable ones.
