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.
