[Necrotizing ulcerative periodontitis. Diagnosis, treatment and follow-up--a case report].Schweiz Monatsschr Zahnmed. 2004; 114(5):479-95.SM
Necrotizing ulcerative gingivitis (NUG) and necrotizing ulcerative Periodontitis (NUP) share many clinical and etiologic characteristics. Both forms are characterized by necrotic gingival tissues, bleeding and pain. Malodor and malaise may be also present. NUG is an infection limited to the gingiva whereas NUP also involves the attachment apparatus. Predisposing factors may include immune dysfunction, poor oral hygiene, cigarette smoking and emotional stress. NUG and NUP might possibly be different stages of the same infection. This case report shows the successful treatment of a patient suffering from NUP.
