A prospective epidemiological study on odontogenic tumours in a black African population, with emphasis on the relative frequency of ameloblastoma.

The persistent view in the literature is that the relative frequency of ameloblastomas is higher in the black population than in Caucasians.

A prospective study was undertaken of all patients presenting with OT to all 16 Nigerian departments of oral and maxillofacial surgery over a 4-year period.
