Acute necrotizing ulcerative gingivitis (ANUG) or necrotizing ulcerative gingivitis (NUG) is a sub-classification of necrotizing periodontal disease, an infection of the gum tissue. This presents as an acute infection of the gingiva without involvement of the other tissues of the periodontium. If the infection has progressed deeper into the periodontal tissues, it is subclassified as "necrotizing ulcerative periodontitis" (NUP).
The condition is also commonly referred to as "trench mouth" and "Vincent's angina", named after French physician Jean Hyacinthe Vincent (1862–1950). Other synonyms include "acute membranous gingivitis", "fusospirillary gingivitis", " fusospirillosis", "fusospirochetal gingivitis", "necrotizing gingivitis", "phagedenic gingivitis", "ulcerative gingivitis", "Vincent stomatitis", "Vincent gingivitis", and "Vincent infection".

Famous quotes containing the word acute:
“Long before I wrote stories, I listened for stories. Listening for them is something more acute than listening to them. I suppose it’s an early form of participation in what goes on. Listening children know stories are there. When their elders sit and begin, children are just waiting and hoping for one to come out, like a mouse from its hole.”
—Eudora Welty (b. 1909)
