Two cases are described of Endosteal Osteoma which developed in the Jaw bone and were painful. The tumors were radiographically characterized by dense radiopaque lesion. The surface was smooth and overlying mucosa was normal in color. Tentative diagnosis was Osteoma. The tumors were treated surgically. Postoperatively the patients made uneventful recovery and the wound healed satisfactory. Postoperative radiograph showed that radiopaque mass had been completely removed. Histologically, biopsy was reported as Central Osteoma. Subsequent follow-up examinations show no recurrence of the lesion or the pain.
