Odontogenic tumors in Port Harcourt: South-South geopolitical zone of Nigeria.
OBJECTIVE
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.


METHODS
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).


RESULTS
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.


CONCLUSIONS
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.
