A relatively rare case of ameloblastic fibro-odontoma occured in the mandible of 5.8-year-old male. He was referred to our clinical office for uneruption of FE and 1-6 with painless swelling in that area.
According to the X-ray examination, a nonuniform radiopaque mass was found in the left mandible, and E and 6 were impacted beneath the mass.
The clinical diagnosis was odontoma.
The impacted teeth E and 6 were separated from the mass easily, so they were conserved.
Three years have passed since the operation, and these teeth have risen to the normal position in the dentition with the aid of orthodontic treatment.
Histopathologically, there was a matrix similar to ameloblastic fibroma. In the matrix of the tumor, hard segments, dentin-like, cementum-like, and bone-like tissues, were included.
Thus it was diagnosed as ameloblastic fibro-odontoma.
According to the special staining, it is found that the hyaluronic acid and glycogen were the tumor products in the tumor mucous.
