Odontogenic fibroma is a rare benign odontogenic tumor in jaw bones which accounts for only 0.1% to 1.5% of all odontogenic tumors and 6.1% if odontomas were not taken into account. Odontogenic fibroma is classified as central and peripheral types according to its location in the jaw bones. Slow growth is a classic feature of this tumor, although cortical bone expansion is seen sometimes, pain is not usually experienced. Apparent swelling or displacement of adjacent tooth and sometimes nerve paralysis are the common reasons for the tumor to be discovered. The treatment choice for odontogenic fibroma is excision, the prognosis is excellent and recurrence is uncommon. Until 2010, only 80 cases of central type odontogenic fibroma were reported in English literature, which outlines its unique entity. Therefore, here we report a case of odontogenic fibroma.
