A patient with pemphigus vulgaris has fragile, desquamative gingiva (positive Nikolsky sign). Which procedure should be AVOIDED?

  1. Routine rubber-cup prophylaxis/aggressive scaling
  2. Gentle plaque control with a soft brush
  3. Topical corticosteroid therapy
  4. Soft-diet recommendations
Show answer and explanation

Correct answer: A. Routine rubber-cup prophylaxis/aggressive scaling

  • A. Correct. Aggressive prophylaxis/scaling can shear the fragile epithelium (Nikolsky positive), worsening blistering and ulceration; gentle care is required.
  • B. Gentle, atraumatic plaque control is appropriate.
  • C. Topical corticosteroids are part of management, not contraindicated.
  • D. A soft diet reduces mucosal trauma and is reasonable.
