Approximate Synonyms

Clinical Information
  • A bacterial infectious process affecting the gums. It is characterized by the development of necrotic, ulcerated, and painful lesions with creation of pseudomembranes extending along the gingival margins.
  • An acute or chronic gingivitis characterized by redness and swelling, necrosis extending from the interdental papillae along the gingival margins, pain; hemorrhage, necrotic odor, and often a pseudomembrane. The condition may extend to the oral mucosa; tongue; palate; or pharynx. The etiology is somewhat unclear, but may involve a complex of fusobacterium nucleatum along with spirochetes borrelia or treponema.
  • Vincent infection where the lesions spread to the soft palate and oropharynx.
