You do all of the following for an aphthous ulcer EXCEPT:

  1. Mouthwash (chlorhexidine)
  2. Laser therapy
  3. Excisional biopsy
  4. Topical corticosteroids
Show answer and explanation

Correct answer: C. Excisional biopsy

  • A. Chlorhexidine mouthwash IS used for aphthous ulcers — it reduces bacterial colonization and secondary infection of ulcers. This IS done.
  • B. Low-level laser therapy IS used for aphthous ulcers — it reduces pain and promotes healing. This IS done.
  • C. EXCISIONAL BIOPSY is NOT performed for aphthous ulcers — it is a treatment for NEOPLASTIC lesions. Aphthous ulcers are self-limiting and benign; removing them surgically is not indicated. Management of aphthous ulcers includes: topical corticosteroids, chlorhexidine rinses, analgesic rinses (lidocaine), laser therapy, and systemic agents for severe recurrent cases (colchicine, thalidomide). Biopsy is only considered if the lesion persists beyond 2-3 weeks to rule out malignancy.
  • D. Topical corticosteroids (triamcinolone acetonide paste) ARE the first-line treatment for aphthous ulcers — they reduce inflammation and pain. This IS done.
