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

AIM: 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. MATERIALS AND 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. CONCLUSION: 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.

Pediatric maxillofacial injuries at a Nigerian teaching hospital: a three-year review.

AIM: To determine the nature of pediatric maxillofacial injuries, according to etiology and characteristics of patients. MATERIALS AND METHODS: The records of patients aged 15 years and below who presented with maxillofacial trauma to the Maxillofacial Clinic of Aminu Kano Teaching Hospital, Kano, Nigeria over a 3-year period were retrospectively examined. Patients' demographic and etiologic factors were obtained and analyzed. A P value of <0.05 was considered significant. RESULTS: A total of 160 patients comprising males, 102 (63.8%) and females 58 (36.2%), were seen over the period of study. The age of patients range from 4 months to 15 years, mean 7.07 ± 4.52 years. There was no gender difference in terms of age (P < 0.05). Road traffic accident (RTA) was the most common etiologic factor accounting for 45.0% of cases. This was followed by fall (40.6%). Animal related injury and violence accounted equally for 3.8%. Soft tissue injuries in the form of abrasion, laceration and avulsion accounted for 70.0% of cases. Other anatomical sites included the mandible (16.3%), dento-alveolar fractures(12.5%), and midface (1.3%). CONCLUSION: Road traffic accident and falls still remains the leading cause of maxillofacial injuries in children in this part of the globe. There is a need to reinforce existing traffic laws that aimed at minimizing the menace of RTA-related accidents.

Temporo-mandibular joint pain dysfunction syndrome: report of two cases and review of literature.

Two cases of TMJ pain dysfunction syndrome were diagnosed and treated between 1990 and 1992. The two cases occurred in females in the 4th decade of life. In the two cases, there was evidence of psychogenic origin but no evidence of organic origin. These cases are being presented because of the common psychogenic origin as aetiological factor in both cases and the quick response to treatment as soon as cause of the disorder was discovered.
