Desquamative gingivitis is associated with all of the following EXCEPT:
Show answer and explanation
Correct answer: E. Dental plaque-induced gingivitis (classic plaque gingivitis — this is the EXCEPTION)
✓ E) Classic plaque-induced gingivitis is the EXCEPTION — it does NOT cause desquamative gingivitis.
Desquamative gingivitis (DG): fiery red, glazed, painful gingiva in middle-aged to elderly females. Gingiva peels/sloughs with minimal trauma. Associated conditions: (1) LICHEN PLANUS (most common); (2) Mucous Membrane Pemphigoid; (3) Pemphigus vulgaris; (4) Bullous pemphigoid; (5) Linear IgA disease; (6) Lupus erythematosus. NOT caused by dental plaque alone — plaque role is 'vague.' Classic plaque gingivitis presents as edematous, erythematous gingiva but does NOT show desquamation/sloughing. DG requires biopsy and dermatology/ophthalmology referral.
