In a patient with pemphigus vulgaris (fragile mucosa, positive Nikolsky), which dental procedure should be AVOIDED?

  1. Air-abrasive/air-powder polishing
  2. Gentle scaling
  3. Fluoride application
  4. Radiographs
Show answer and explanation

Correct answer: A. Air-abrasive/air-powder polishing

  • A. Correct. Air-abrasive/air-powder polishing traumatizes fragile epithelium and can trigger sloughing/bullae in Nikolsky-positive mucosa.
  • B. Gentle scaling can be done atraumatically with care.
  • C. Fluoride application is safe.
  • D. Radiographs are unaffected by the mucosal fragility (with gentle film placement).
