Jt. Arotiba et al., ODONTOGENIC-TUMORS - A 15-YEAR REVIEW FROM IBADAN, NIGERIA, British journal of oral & maxillofacial surgery, 35(5), 1997, pp. 363-367
Objective-To establish the incidence of odontogenic tumours in Nigeria
we present our experience during the 15-year period 1980-94, Design-R
etrospective review of histopathological specimens and case notes, Set
ting-Teaching hospital, Nigeria, Subjects-128 Patients with histologic
ally confirmed odontogenic tumours out of a total of 415 with tumours
of the mouth and jan: Main outcome measures-Incidence, treatment, and
recurrence rate, Results-Ameloblastoma (n = 21, 16%) and adenomatoid t
umour (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 maxi
lla:mandible ratios 1:9, 1.1:1, and 2:1, The more radical the resectio
n of ameloblastomas the less likely were they to recur, Conclusion-Fur
ther research is required to explain the high incidence of odontogenic
tumours in Nigeria, particularly ameloblastomas.
