What should NOT be done when treating a patient with Mucous Membrane Pemphigoid?
Show answer and explanation
Correct answer: A. Prophy jet (air polishing)
Prophy jet should NOT be used — the high-pressure air-powder can traumatize fragile blistered mucosa and trigger new lesions (Koebner phenomenon).
- A. ✅ CORRECT – Prophy jet is contraindicated; mechanical trauma induces new blister formation.
- B. ❌ Topical anesthetics are appropriate for pain management.
- C. ❌ Gentle scaling can be performed carefully.
- D. ❌ Topical corticosteroids are a mainstay of MMP treatment.
