OBJECTIVE
To establish the incidence of odontogenic tumours in Nigeria we present our experience during the 15-year period 1980-94.
DESIGN
Retrospective review of histopathological specimens and case notes.
SETTING
Teaching hospital, Nigeria.
SUBJECTS
128 Patients with histologically confirmed odontogenic tumours out of a total of 415 with tumours of the mouth and jaw.
MAIN OUTCOME MEASURES
Incidence, treatment, and recurrence rate.
RESULTS
Ameloblastoma (n = 21, 16%) and adenomatoid tumour (n = 16, 13%). Patients' ages ranged from 8 to 75 years (mean 33 for ameloblastoma, 31 for fibromyxoma, and 22 for adenomatoid tumour). The corresponding male:female ratios were 3:2, 2:3, and 1:1, and maxilla:mandible ratios 1:9, 1.1:1, and 2:1. The more radical the resection of ameloblastomas the less likely were they to recur.
CONCLUSION
Further research is required to explain the high incidence of odontogenic tumours in Nigeria, particularly ameloblastomas.
目的
为确定尼日利亚牙源性肿瘤的发病率，我们介绍了1980 - 1994年这15年间的经验。
设计
对组织病理学标本和病例记录进行回顾性研究。
地点
尼日利亚的教学医院。
研究对象
在总共415例口腔颌面部肿瘤患者中，有128例经组织学确诊为牙源性肿瘤。
主要观察指标
发病率、治疗方法及复发率。
结果
成釉细胞瘤（n = 21，16%）和腺瘤样瘤（n = 16，13%）。患者年龄范围为8至75岁（成釉细胞瘤平均33岁，纤维黏液瘤平均31岁，腺瘤样瘤平均22岁）。相应的男女比例分别为3:2、2:3和1:1，上颌骨与下颌骨比例分别为1:9、1.1:1和2:1。成釉细胞瘤切除越彻底，复发可能性越小。
结论
需要进一步研究来解释尼日利亚牙源性肿瘤尤其是成釉细胞瘤的高发病率。
