Introduction. Fibrous Ameloblastic Odontoma (FAO) is an uncommon benign odontogenic tumor whose characteristics are generally similar to those of an ameloblastic fibroma except that that it has varying amounts of calcified tissue. It is usually found associated with compacted teeth and its incidence is slightly more common in the inferior maxilla. Materials and Methods. 17-yearold patient goes to the doctor because of a lesion located near the right mandible angle, found in an X-ray. After performing a physical exam, histological tests and taking images it was diagnosed as FAO and then surgically removed. Results. Although the patient fell into the typical age range and they FAO was located in the typical area, the definitive diagnostic could only be decided until after the results of the histological study of the removed tooth were reviewed. Discussion. FAO diagnosis normally creates confusion from both a histological and a clinical radiographic point of view. It is difficult differentiate between FAO and Complex Immature Odontoma (OIC). Like in this case, the differences are detected later when the histological study is complete. Conclusion. FAO is independent from OIC and its diagnostic greatly depends on the histological discoveries and the clinical radiographic correlation carried out when the pathology is first dealt with.
