Abstract
The traumatic bone cyst appears as a rare pathology, and it is considered a benign osseous lesion of unclear etiology. This study aims to report a case of traumatic bone cyst in the mandible. A 16-year-old female leucoderm patient discovered a well-delimited radiolucent lesion in the mandibular symphysis after performing radiographic examinations for orthodontic appliance. At physical examination, there was no facial asymmetry or swelling in the buccal vestibule. The sensitivity test was positive in the antero-inferior dental units. Diagnostic hypothesis included traumatic bone cyst, odontogenic keratocyst, and cement-bone dysplasia. Surgical exploration was performed, and an empty bone cavity containing small tissue fragments was found. The patient is being followed up with radiographic signs suggestive of bone neoformation. Therefore, the clinical, imaging, transoperative, and histologic features show fundamental importance because of the need to consider this pseudocyst as diagnostic hypothesis concerning radiolucent lesions of the jaws.
