Demographic and clinical data associated with acute necrotizing ulcerative gingivitis in a dental school population*. (ANUG-demographic and clinical data)

Abstract
The prevalence of demographic and clinical factors of patients diagnosed as having ANUG [acute necrotizing ulcerative gingivitis] was determined by the presence of painful, bleeding, necrotic and ulcerated interproximal gingival papillae. ANUG patients were evenly divided between males and females relative to the general clinic population. Of the patients with ANUG, 58% were under 25 yr of age as compared to 31% under 25 in the general clinic population. Overall, the ANUG group accounted for 1.4% of the < 34 age group in the general clinic population. Of the ANUG group 76% had a high school education or less with 67% having < $5000 annual income. Only 20% presented with elevated temperature. Only 6% of the patients with ANUG were non-smokers as compared to 63% in a matched control group. Of great significance was the fact that only 1 patient with ANUG was black as compared to a 41% black population in the clinic population.
