A retrospective study of odontogenic tumors (OTs) in Port Harcourt was undertaken to establish its prevalence and compare with known data in the literature from Nigeria and elsewhere.
All pathologically diagnosed OTs between 2008 and 2013 at the archives of the Department of Oral Pathology and Oral Biology of the University of Port Harcourt/University of Port Harcourt Teaching Hospital were retrospectively studied and classified according to the 2005 WHO classification of OTs and allied diseases. These were recorded into a computer and analyzed using Statistical Package for Social Sciences (SPSS 21.0, Inc., Chicago, IL, USA).
A total of sixty-three cases of OTs were recorded for the period under review. Fifty-two of these were cases of ameloblastoma (82.54%). This was followed by adenomatoid odontogenic tumour (AOT) 4 (6.35%) and odontogenic myxoma 3 (4.76%). Most lesions were seen within the second to fourth decades of life and mandible was most frequently affected.
It is concluded that the pattern of occurrence of OTs in Port Harcourt followed a general pattern in Nigeria and other African countries but slightly differs from findings from other parts of the world.
对哈科特港的牙源性肿瘤（OTs）进行回顾性研究，以确定其患病率，并与尼日利亚和其他地区文献中的已知数据进行比较。
对2008年至2013年期间哈科特港大学/哈科特港大学教学医院口腔病理学和口腔生物学系档案中所有经病理诊断的OTs进行回顾性研究，并根据2005年世界卫生组织牙源性肿瘤及相关疾病分类进行分类。将这些数据录入计算机，并使用社会科学统计软件包（SPSS 21.0，美国伊利诺伊州芝加哥市SPSS公司）进行分析。
在本研究期间共记录了63例OTs病例。其中52例为成釉细胞瘤（82.54%）。其次是腺样牙源性肿瘤（AOT）4例（6.35%）和牙源性黏液瘤3例（4.76%）。大多数病变见于生命的第二个至第四个十年，下颌骨最常受累。
得出的结论是，哈科特港OTs的发生模式与尼日利亚和其他非洲国家的总体模式一致，但与世界其他地区的研究结果略有不同。
