trench mouth n.
An acute, sometimes recurrent lesion of the mouth, gums, and throat often associated with fusiform bacilli and spirochetes, marked by ulceration and necrosis of the gum margin, destruction of the interdental papillae, and foul breath. Also called acute necrotizing ulcerative gingivitis, fusospirillary gingivitis, fusospirochetal gingivitis, necrotizing ulcerative gingivitis, ulceromembranous gingivitis, Vincent's angina, Vincent's disease.
acute and painful infection of the tooth margins and gums that is caused by the symbiotic microorganisms Bacillus fusiformis and Borrelia vincentii. The chief symptoms are painful, swollen, bleeding gums; small, painful ulcers covering the gums and tooth margins; and characteristic fetid breath. The ulcers may spread to the throat and tonsils. Fever and malaise may also be present. Vincent gingivitis can occur after a prolonged failure to brush one's teeth, though there are many other predisposing factors, such as vitamin deficiencies, emotional stress, and so on. The infection is readily treated by bed rest, the administration of penicillin or other antibiotics, and the use of antiseptic mouth rinses. Regular tooth brushing is the chief preventive measure
