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.
本研究的目的是确定肯尼亚内罗毕肯雅塔国家医院（KNH）牙科部门患者中急性坏死性龈炎（ANG）的发病率、性别和年龄分布、种族及季节性变化。对1992/1993年在KNH牙科部门就诊患者的病历进行审查，以确定ANG的阳性诊断、年龄、性别、临床表现及接受的治疗。在接受治疗的53572名患者中，有（0.15%）患ANG。他们的年龄范围为1.5至46岁（平均=14.5岁），其中58.5%低于11岁，32.9%在21至40岁之间。受影响最严重的种族群体是卢奥族和基库尤族，72%的患者在3月和4月以及9月至12月期间就诊。研究得出结论，ANG的发病率较低，ANG影响儿童和成人，且ANG存在季节性变化。
