AB : Traumatic bone cyst is a pathologic cavity that is not lined with epithelium. It is, therefore, not a true cyst. It may be a normal variant rather than a disease process. The etiology of the condition is unknown. This condition is occured widely ranging ages(2 to 75years), however, most are found during the second decade of life. Radiographically, this condition is radiolucent lesion with well-defined outline, scalloping of superior margins. Cyst enucleation and curettage is the treatment of choice. The authors compared and analyzed the clinicoradiologic features of the five cases of traumatic bone cyst, diagnosed at the Dental college hospital in Chosun University, Kwangju, Korea.
The five cases were shown the follwed results;
1. 3cases occured in second decade of life & no significant sex differences (M:F, 2:3) All cases occurred in mandible.
2. Two patients complained symptoms, but three cases had no symptom with encountering during routine examination.
3. In 3 of 5cases, teeth vitality existed except one tooth and no checking of teeth vitality in two cases.
4. All cases didn't have any accurate trauma history, but one case was in orthodontic treatment, another case was postextraction site area.
5. Radiologically, "scalloping appearance" were evident in all cases; in 3 cases, multilocular tendency & only one case seen intact mandibular canal image.
6. Histologically, alll section showed bone trabeculae with blastic activity, 2 cases showed no epithelial lining, and other 2 cases were seen innflammatory cell infiltration in edematous tissue.
7. Surgical intervention (curettage) was that treatment of choice.
