[A case reported of an ameloblastic fibroma in which involved three right molars in a teenager].

Ameloblastic fibroma is a benign tumor of mixed odontogenic origin, which occurs in ages from 12 to 15 years, frequently in the molar area. Generally it is asymptomatic, however the biggest lesions can be associated to pain and swelling. Using X-ray they appear well defined, transparent, with a sclerotic radio-opaque border; occasionally they can simulate a dentigerous cyst.
