title: Traumatic bone cyst suggestive of large apical periodontitis.
abstract: This case report shows the importance of establishing the correct diagnosis to provide the appropriate treatment options The traumatic bone cyst is a pseudocyst, usually asymptomatic and found by a routine radiographic examination. Unicystic radiolucency is almost always observed, which can involve the periradicular area of teeth, simulating an inflammatory lesion of endodontic origin. Differential diagnosis should include other pathologies, such as odontogenic keratocyst, central giant cell granuloma, and unicystic ameloblastoma. Its etiology and pathogenesis are not yet definitely established. In the present study, after review of the medical and dental histories and clinical and radiographic examination of teeth #24-27 (pulpal vitality test showed positive), the primary diagnosis was traumatic bone cyst. The planning was excisional biopsy. After surgical exploration, only one small blood clot was observed in the intraosseous socket, which was carefully curetted and filled with blood. A clinical and radiographic examination after 6 months showed apical formation and pulpal vitality preserved.
