  1. A free gingival graft is harvested primarily from which intraoral donor site?

    Answer: Hard palate

    The hard palate provides keratinized epithelium and connective tissue ideal for free gingival grafts to increase the zone of attached gingiva.

  2. Which radiographic bone loss pattern is most characteristic of localized aggressive periodontitis affecting first molars?

    Answer: Arc-shaped (arcuate) vertical bone loss

    Localized aggressive periodontitis classically shows an arc-shaped vertical bone loss pattern on the mesial and distal aspects of first molars.

  3. The biologic width is defined as the combined measurement of:

    Answer: Junctional epithelium and supracrestal connective tissue attachment

    Biologic width consists of junctional epithelium (~0.97 mm) plus supracrestal connective tissue (~1.07 mm), totaling approximately 2 mm.

  4. Which antibiotic regimen is specifically recommended as an adjunct for treating aggressive periodontitis caused by A. actinomycetemcomitans?

    Answer: Amoxicillin plus metronidazole

    The combination of amoxicillin and metronidazole has strong evidence as an adjunct to scaling and root planing for aggressive periodontitis, particularly against A. actinomycetemcomitans.

  5. Guided tissue regeneration (GTR) uses a membrane to:

    Answer: Exclude epithelium and gingival connective tissue from the healing wound

    GTR membranes act as physical barriers that exclude fast-growing epithelial and connective tissue cells, allowing slower-growing PDL and bone cells to repopulate the defect.

  6. Which condition is characterized by pronounced gingival inflammation with pseudopockets but no true attachment loss?

    Answer: Gingivitis

    Gingivitis features inflamed, edematous gingiva that may form pseudopockets due to tissue swelling, but there is no apical migration of the junctional epithelium or true attachment loss.

  7. The Papilla Preservation Technique (PPT) in periodontal surgery is primarily designed to:

    Answer: Maintain interdental papilla for better esthetic outcomes and wound closure

    The PPT keeps the interdental papilla intact by redirecting incisions, preserving esthetics and achieving primary closure over interdental bone defects, especially important in the anterior region.
