Gt. Arotiba et al., THE ADENOMATOID ODONTOGENIC-TUMOR - AN ANALYSIS OF 57 CASES IN A BLACK-AFRICAN POPULATION, Journal of oral and maxillofacial surgery, 55(2), 1997, pp. 146-148
Purpose: This study analyzed the findings in a large series of adenoma
toid odontogenic tumors (AOT) in Nigerians. Patients and Methods: Hosp
ital records of all cases of AOT diagnosed at three teaching hospitals
were reviewed and analyzed. Results: Most of the tumors were intraoss
eous (central) (98.3%) and of the follicular type (75%), Females were
more frequently affected than males (1.4:1), and patients in their sec
ond decade of life were most frequently affected (75%), Patients with
follicular AOT were relatively younger (15.2 +/- 5.6 years) than those
with extrafollicular tumors (20.9 +/- 13.8 years), However, males who
presented with extrafollicular tumors (14.6 +/- 3.9 years) were relat
ively younger than their female counterparts (24.9 +/- 16 years), The
maxilla was affected nearly twice as often as the mandible (1.8:1), an
d the canine tooth was frequently embedded in the tumor (76.9%), Altho
ugh follicular tumors were most frequently located in the maxilla (76.
3%), extrafollicular tumors were more commonly found in the mandible (
69.2%). Conclusion: The distribution of this tumor in black Africans d
oes not appear to be substantially different from that reported in cau
casians.
