Ameloblastic fibroma: report of two cases.

Two cases of ameloblastic fibroma are described. One case was a seven-year-old girl, the other a 13-year-old boy. In both cases the tumour was located in the posterior part of the maxilla. Both neoplasms were associated with failure of tooth eruption, in one case a primary molar, in the other case a permanent molar. Local excision was performed in both cases, with a recurrence observed in one case ten months after surgery.
