Demography and seasonal variation of acute necrotising gingivitis in Nairobi, Kenya.
The objectives of this study were to determine the frequency of Acute Necrotising Gingivitis (ANG), its sex and age distribution, ethnicity and seasonal variation amongst patients at the Dental Unit of Kenyatta National Hospital (KNH) in Nairobi, Kenya. Cards of patients who were seen in the Dental Unit of KNH in 1992/1993, were scrutinised for positive diagnosis of ANG, age, sex, presenting signs and symptoms and treatment that was given. Of the 53,572 patients who were treated, (0.15 per cent) had ANG. Their age range was 1.5-46 years (Mean = 14.5 years), with 58.5 per cent being below 11 years and 32.9 per cent being between 21 and 40 years. The most affected ethnic groups were the Luos and Kikuyus, while 72 per cent of the patients were seen in March and April, and between September and December. It is concluded that the frequency of ANG was low, ANG affected children and adults, and that ANG varied seasonally.
