The aim of this study was to determine the relative frequencies and clinico-pathological features of odontogenic tumours affecting the jaw bones of patients in the first two decades of life and of rural and periurban African extract.
Files of patients younger than 20 years of age diagnosed over a period of 26 years with odontogenic tumours were retrieved and analysed for gender, site, tumour size and radiographic appearance.
33% of odontogenic tumours diagnosed in the population sample presented during the first 2 decades of life. Ameloblastoma was the most frequent benign tumour (43%) followed by keratocystic odontogenic tumour (19%) and adenomatoid odontogenic tumour (10%). Four patients (1.6%) presented with ameloblastic carcinoma.
Owing to the unique population demographics of South Africa, odontogenic tumours in the first two decades of life comprise a larger percentage of the total number of cases than in other communities. The frequency of the different odontogenic tumour types generally follows the pattern of those reported in Africa, China and parts of South America. Radiographic examination is indispensable in establishing an accurate diagnosis.
本研究旨在确定发生于非洲农村和城郊地区、年龄在 20 岁以下的颌骨源性肿瘤的相对频率和临床病理特征。
收集了 26 年来年龄小于 20 岁的颌骨源性肿瘤患者的档案，分析了性别、发病部位、肿瘤大小和影像学表现。
在人群样本中，33%的颌骨源性肿瘤发生于 20 岁之前。最常见的良性肿瘤是造釉细胞瘤（43%），其次是角化囊肿（19%）和腺牙源性肿瘤（10%）。4 例（1.6%）患者表现为成釉细胞癌。
由于南非独特的人口统计学特征，颌骨源性肿瘤在 20 岁之前的比例高于其他社区。不同颌骨源性肿瘤的发病率与非洲、中国和南美洲部分地区的报道模式基本一致。影像学检查对明确诊断必不可少。
