The study reported in this paper was carried out in the Northwestern and Southwestern regions of Nigeria, between October 1996 and April 1998. The study examined the possible contributory role of living conditions in the development of acute necrotizing gingivitis (ANG) or noma from oral lesions. Questionnaire data obtained from 42 fresh noma cases seen in the Northwest and four fresh cases seen in the Southwest were examined. In addition 46 cases of advanced ANG from the Southwest were included. The main focus was to compare some of the environmental living conditions of cases with advanced ANG and those with noma in these regions. All the noma and ANG cases were seen in children aged 2-12 years. The level of good oral hygiene practices and general environmental living conditions were significantly higher in the Southwest than in the Northwest. Data also showed that living in close proximity with livestock was significantly higher in the Northwest than in the Southwest (P < 0.05). The environmental living conditions of children in the Northwest were further compounded by poor sanitary faecal disposal practices as well as minimal access to potable water. The overall data indicated that living in substandard accommodations, exposure to debilitating childhood diseases, living in close proximity to livestock, poor oral hygiene, limited access to potable water and poor sanitary disposal of human and animal faecal waste could have put the children in the Northwest at higher risk for noma than the children in the Southwest. These could have been responsible for the higher prevalence of noma in the Northwest than in the Southwest.
