Abstract
Cases of simple bone cysts (SBC) are comparatively rare in the oral region. Recently, we experienced a case of 12-year old female with SBC.
This patient has not particular general failures. Radiographical examinations showed some abnormal aspects as follows, we found a circumferentially obscure single cyst-like radio lucency in a panorama X-ray, a root apical projection of 7 into the radiolucent region in a mandibular lateral body view X-ray, and no absorptive findings of alveolar lamina dura in the dental X-ray film. We performed a curretage under local anesthesia with a clinical diagnosis as a left mandibular cyst. The bone cavity was filled with blood-like substances. Bundles of inferior alveolar nerve and vessels were observed on the floor part of the cavity. The granulative tissues and the epitherial cyst wall were not observed. The sarrounding of the bone of this cavity is flat and smooth. Based on the above mentioned findings, we diagnosed this lesion as SBC. After the operation no recurrence has been observed for 2 years 7 months.
