OPTION 3

Necrotizing ulcerative gingivitis (NUG) is a microbial disease of the gingiva that most often occurs in an impaired host. It manifests with the characteristic clinical signs of necrosis and sloughing of the gingival tissues and may be accompanied by systemic symptoms.
A poor diet has been reported as a predisposing factor in ANUG. Nutritional deficiencies such as vitamin B and vitamin C accentuate the response of gingival tissues produced by increased pathogenic flora.
Several researchers have found an increase in the fusospirochetal flora in patients with nutritionally-deficient diets.
Debilitating diseases: May predispose to the development of acute necrotizing ulcerative gingivitis. Such systemic disturbances are metallic intoxication, severe gastrointestinal disorders, blood dyscrasias such as anemia, leukemia and acquired immunodeficiency syndrome.
⸙ Key Concept:        
Debilitating Disease: Systemic disease that impair immunity cause ANUG. Disease that predispose to ANUG are:
֍ Chronic diseases such as syphilis, cancer
֍ Severe gastrointestinal disorders (ulcerative colitis)
֍ Blood dyscrasias (leukemia and anemias)
֍ A.I.D.S.
֍ Nutritional deficiencies resulting from debilitating disease may be additional predisposing factor.
