Large ameloblastic fibro-odontoma in a 7-year-old girl with analysis of 108 cases.

BACKGROUND: Odontogenic tumors such as ameloblastic fibro-odontoma (AFO) are rare conditions in children and are often asymptomatic. AFOs are found by routine clinical and radiological examination or when they cause obvious intra- or extra-oral swelling.

MATERIALS AND METHODS: A case of an AFO in a 7-year-old girl is described, and 107 cases from the literature and this report are analyzed.

RESULTS: The total of 108 cases revealed the average age at presentation of AFO to be 6.3 years in boys and 9.6 years in girls. There was a slight male predilection and AFO lesions most often occurred in the posterior mandible. AFO was almost always associated with an unerupted tooth or teeth.

CONCLUSIONS: While the recurrence rate of AFO was found to be 5.5%, long-term postoperative clinical and radiological follow-up is advised to ensure no future signs of aggressive recurrence.
