Gingivitis, ulcerative

: This is trench mouth, a progressive painful infection with ulceration, swelling and sloughing off of dead tissue from the mouth and throat due to the spread of infection from the gums. Certain germs (including fusiform bacteria and spirochetes) have been thought to be involved, but the full story behind this long- known disease is still not clear. Ulcerative gingivitis (VincentÆs gingivitis) is named for the French physician Henri Vincent (1862-1950) and gingivitisö of course refers to the gingiva (the gums) which are inflamed (-itis). As with most poorly understood diseases, VincentÆs gingivitis goes by many other names including acute necrotizing ulcerative gingivitis (ANUG), acute membraneous gingivitis, fusospirillary gingivitis, fusospirillosis, fusospirchetal gingivitis, necrotizing gingivitis, phagedenic gingivitis, ulcerative gingivitis, VincentÆs angina, VincentÆs infection, and VincentÆs stomatitis.
