Necrotizing ulcerative gingivitis and cancrum oris (noma) in Ibadan, Nigeria.

This study analyzed 58 cases of necrotizing ulcerative gingivitis (NUG) and 5 cases of cancrum oris among children who sought treatment at the Ibadan University College Hospital, Dental Centre in a 1-year period. The peak occurrence of NUG was among 4- and 5-year old children and 84.5% of them were in the 2 to 7 years age range. Seventy-two percent presented in the rainy season with positive history of recent febrile illness in 55 cases. There was no statistically significant association of NUG and rainy season. Possible predisposing factors in NUG and cancrum oris such as malnutrition, infectious childhood diseases, HIV infection, and immune compromise are discussed. It is suggested that children at risk should be advised to maintain good oral hygiene, adequate nutrition, and proper medical care.

Epidemiology of necrotizing ulcerative gingival lesions in adolescents.

OBJECTIVE AND BACKGROUND: Relatively little is known about the epidemiology of necrotizing ulcerative gingival lesions (NUG) in adolescent populations. Most studies have comprised special target groups, such as military recruits, HIV patients, or severely malnourished subjects. METHODS: A multistage random cluster sampling scheme was used to obtain a sample of 9203 students aged 12-21 years from 98 of a total of 618 high schools in Santiago, Chile. Students were given a clinical oral examination and questionnaire information was obtained on smoking and oral hygiene habits, dental attendance patterns, and diabetic status. The diagnostic criteria for NUG were the presence of necrosis and ulceration of at least one interproximal papillae. RESULTS: The estimated prevalence of NUG was 6.7% (95% CI = [6.2; 7.3]). A multivariable logistic regression analysis showed that last seeing a dentist more than 1 year ago (OR = 1.60), or never (OR = 1.93), and reporting diabetes (OR = 2.12) showed a significant positive association with the presence of NUG; whereas neither gender nor smoking were important predictors. Students aged 18-21 years were more, albeit statistically insignificantly, likely to have NUG than were younger students (OR = 1.40). CONCLUSIONS: Our observation that reporting to be diabetic was positively associated with the presence of NUG is interesting, as diabetes has never been addressed as a possible risk factor. As the association between diabetes and periodontitis in adults is thought to relate to impaired function of neutrophils, microangiopathy, and impaired wound healing this finding suggests a significant role of the host response also for the occurrence of NUG.
