The correct answer is:-
Necrotizing ulcerative gingivitis

Explanation:-

Necrotizing ulcerative gingivitis and periodontitis usually occur because of the predominance of the anaerobic fusobacteria and spirochetes within the oral cavity, specifically underneath the gingiva.

This is a case of necrotizing ulcerative gingivitis (NUG), not necrotizing ulcerative periodontitis (NUP), because the patient is not experiencing bone loss.

Debridement of the affected gingiva with an adjunctive prescription of chlorhexidine 0.12% rinse will help stop the progression of necrotizing ulcerative disease.

Acute necrotizing gingivitis signs and symptoms include the following:

• Pain
• Interproximal necrosis of the papilla (blunting of the papilla)
• Bleeding gingiva
• Fetid odor
• Low-grade fever
• Pseudomembrane

Acute necrotizing gingivitis risk factors include the following:

•Poor oral hygiene
•Smoking
•Malnutrition
•Fatigue
•Stress
•Immunocompromised patients
