acute necrotizing ulcerative gingivitis (ANUG),

a recurrent periodontal disease of sudden onset that primarily affects the interdental papillae. It is characterized by painful inflammation and ulceration of the gums, leading to the formation of craterlike defects and ulcers. The necrotic tissue appears as a gray membrane that is easily sloughed off. There also may be fever, bone destruction, a fetid odor, and enlarged lymph nodes in the throat and neck. It is usually associated with poor oral hygiene and stress and is most common in conditions in which there is crowding of the teeth and malnutrition. Treatment includes chlorhexidine mouthwashes, antibiotics, analgesics, and dental care to remove and disrupt bacterial flora. Also called trench mouth, Vincent's angina, Vincent's infection. See gingivitis.
