Osteoblastoma of the mandible with root resorption: a case report.

This article reviews the clinical behavior, histologic features, differential diagnosis, and treatment of a benign osteoblastoma. Benign osteoblastoma is a rare tumor constituting 1% of all primary bone tumors. Only 15% of osteoblastomas occur in the skull and jaw bones. The most common clinical presentation is a painful or tender swelling. A case is presented of a 21-year-old female who had noted discomfort for approximately 2 years, and the pain was not relieved by any analgesic. The choice of treatment was local excision and curettage. In this case, root resorption of the adjacent tooth, which is not a characteristic behavior of osteoblastoma, is seen.
