Osteoblastoma, which is a rare benign neoplasm of osteoblastic differentiation, accounts for fewer than 1% of all primary bone tumors.1It usually presents in the vertebral column, long bones, and small bones of the hands and feet.1,2However, 77 cases arising in the jaws have been reported to date.1There is a male predilection, with a male to female ratio of 2:1.2-5Osteoblastomas seem to occur predominantly on the left side of the posterior mandible,1as in the present case. Most patients (90%) with osteoblastoma are younger than 30 years.4,6
