Vincent's angina, also known as trench mouth, is a progressively painful infection characterized by swelling and the shedding of dead tissue from the mouth and throat, resulting from the spread of infection from the gums. It is believed to involve certain bacteria and spirochetes. The most effective treatment for Vincent's angina involves a specific approach. Named after the French physician Henri Vincent (1862-1950), the term "angina" is derived from the Latin "angere," which means "to choke or throttle." Due to its complex nature, this condition is known by various names, including acute necrotizing ulcerative gingivitis (ANUG), acute membranous gingivitis, fusospirillary gingivitis, fusospirillosis, necrotizing gingivitis, phagedenic gingivitis, ulcerative gingivitis, Vincent gingivitis, among others.
