Acute Necrotizing Ulcerative Gingivitis (ANUG) Synonyms

Acute Necrotizing Ulcerative Gingivitis, commonly known as ANUG, is a severe gum infection that affects the gums and surrounding tissues. This condition is also referred to by several other names, including:

• Trench Mouth: This term originated during World War I when soldiers in the trenches developed this painful gum infection due to poor oral hygiene and stress.


• Acute Ulcerative Gingivitis: This name describes the acute nature of the condition, characterized by the sudden onset of painful gum ulcers.


• Vincent's Infection: Named after the French physician who first described the condition, Dr. Jean Hyacinthe Vincent, this term is used to acknowledge his contribution to understanding ANUG.


• Fusospirochetal Gingivitis: This name highlights the specific bacteria involved in causing ANUG, which are Fusobacterium and Spirochetes.


• Acute Necrotizing Ulcerative Gingivostomatitis: This term emphasizes that the infection not only affects the gums but can also extend to involve the oral mucosa.

It is important to note that regardless of the name used, ANUG refers to the same condition characterized by painful, ulcerated gums, bad breath, and a distinct metallic taste in the mouth. ANUG can cause significant discomfort and requires prompt treatment to prevent further complications.
