Periodontal Flap Surgery Quiz

Which of the following is not a primary objective of periodontal flap surgery?

• Access for root planing

• Gingival depigmentation

• Pocket wall resection

• Access for regenerative procedures

Which incision is made from the bottom of the pocket to the alveolar bone?

• Internal bevel incision

• Interdental incision

• Vertical incision

• Crevicular incision

Which flap technique is primarily designed to provide access for root therapy but not pocket elimination?

• Apically displaced flap

• Modified Widman flap

• Undisplaced flap

• Papilla preservation flap

In the Modified Widman flap, the initial internal bevel incision is placed:

• At the mucogingival junction

• 2–3 mm from the gingival margin

• 0.5–1 mm from the gingival margin

• Directly on the alveolar crest

The apically displaced flap helps in:

• Increasing gingival recession

• Reducing the width of attached gingiva

• Converting unattached pocket wall into attached gingiva

• Removing alveolar bone

Which flap technique requires the incision to begin at or near the projected bottom of the pocket?

• Modified Widman flap

• Apically displaced flap

• Undisplaced flap

• Palatal flap

Which of the following flap designs retains the entire interdental papilla for regenerative procedures?

• Undisplaced flap

• Modified Widman flap

• Papilla preservation flap

• Conventional flap

In distal molar surgery, incisions must be confined to attached gingiva primarily to:

• Increase bleeding

• Improve esthetics

• Prevent flap management difficulties

• Simplify suturing

In palatal flap procedures, the flap is typically:

• Easily apically displaced

• Always full-thickness

• Non-keratinized

• Less mobile and requires thinning

A full-thickness flap differs from a split-thickness flap in that it includes:

• Only epithelium

• Epithelium and connective tissue only

• Epithelium, connective tissue, and periosteum

• Only periosteum
