[The ameloblastic fibroma. An odontogenic tumor in the growth period].

Nine cases of ameloblastic fibroma are described and compared with published data on this odontogenic tumour. The median age of the 7 male and 2 female patients was 11 years (range 2-17 yrs.). The tumour was localized in the posterior segment of the mandible and less often in the maxilla. The neoplasia was frequently associated with impaction and agenesis of teeth. Although recurrences of ameloblastic fibromas are rare, long-term follow-up is recommended.
