All of the following are appropriate management options for recurrent aphthous ulcers EXCEPT:

  1. Excisional biopsy of the ulcer
  2. Topical anesthetic gel for symptomatic relief
  3. Topical corticosteroids
  4. Chlorhexidine mouthrinse
Show answer and explanation

Correct answer: A. Excisional biopsy of the ulcer

  • A. Correct (the EXCEPTION). Aphthous ulcers are self-limiting and heal in 7–14 days; excising them is destructive, unnecessary, and creates a new wound. Biopsy is reserved only for an ulcer that fails to heal beyond 2–3 weeks, where malignancy must be excluded — and even then, incisional biopsy of the margin is the technique, not excision of a routine aphtha.
  • B. Topical anesthetics are appropriate supportive care for pain.
  • C. Topical steroids are first-line and shorten the course of the lesion.
  • D. Chlorhexidine reduces secondary bacterial colonization and can shorten healing time.
