Which condition can be a result of an allergic reaction?

1. Pemphigus vulgaris

2. Necrotizing ulcerative gingivitis

3. Aggressive periodontitis

4. Desquamative gingivitis

The correct answer is: Desquamative gingivitis

Desquamative gingivitis is a condition that can indeed be associated with allergic reactions. This condition is characterized by the inflammation and peeling of the gingival tissue, which can be triggered by various factors, including allergens. Allergic reactions can cause the mucous membranes to become irritated and inflamed, leading to the symptoms observed in desquamative gingivitis. On the other hand, pemphigus vulgaris is an autoimmune condition rather than a strictly allergic one, characterized by blistering of the skin and mucous membranes, which does not primarily originate from an allergic response. Necrotizing ulcerative gingivitis, often linked to infections and stress rather than allergies, involves the death of gum tissue and is typically associated with poor oral hygiene and certain systemic conditions. Aggressive periodontitis is a severe form of periodontal disease that has a distinct bacterial etiology and is not classified as a result of an allergic response. In summary, the link between allergic reactions and desquamative gingivitis highlights the importance of recognizing allergic components when assessing inflammatory conditions of the oral mucosa.
