Introduction: Ossifying fibroma is a benign fibro-osseous neoplasm of the jaw and craniofacial complex, somewhat rare and aggressive that has generated a degree of controversy regarding diagnosis, classification and treatment. It frequently targets the mandible, but seldom the maxillary. It is usually a unilocular lesion with a well-defined, thinly corticated margin radiographically, although various patterns have been noted. Histopathologically these are composed of fibrous tissues with calcified structures resembling bone and cementum. Surgical resection is the treatment of choice.

Objectives: The aim of this study is to evaluate the principal clinical and radiological features of ossifying fibroma involving the jaw bone. And the differences at the surgical procedure of cases of central ossifying fibroma with the so-called juvenile active ossifying fibroma.

Methods: Reported of 5 cases all the cases had adequate radiographs and clinical information and were histopathologically confirmed as ossifying fibroma. Varying shapes of the lesion including cystic lesion and mixed density lesion are presented. All are different manifestations of central ossifying fibroma. The surgical procedure of these cases is present.

Conclusion: OF occur more frequently in female patients, in our report are 3 male and 2 female. In our report 3 are in maxilla and 2 in mandible. Our cases occur between the first and fourth decade of life. All present as a well-defined, mixed lesion radiographically. All the cases present different local aggressiveness. The cases are treated by radical excision without subsequent recurrence. The surgical procedure is different in each case. Juvenile ossifying fibroma is the more aggressive presentation.
