Management of Radicular cyst following deficient orthodontic treatment : Case Report

Root cysts are inflammatory odontogenic cysts of the dental areas of the jaws. Most of these lesions involve the apex of the offending tooth and present as well-defined radiolucencies. Because of their similar clinical features to other more common lesions of the oral cavity, the differential diagnosis should include dentinal cyst, ameloblastoma, odontogenic keratocyst, periapical cementoma, and Pindborg tumor. The present case report documents a root cyst associated with non-carious tooth originating from an old defective gold thodontic treatment. On the basis of clinical, radiographic, and histopathologic findings, the present case was diagnosed as a root cyst. The clinical characteristics of this cyst can be considered interesting and rare owing to the unusual origin. The tooth was treated with endodontic therapy, then the lesion was enucleated surgically associated with apical resection; all other teeth and vital structures were preserved, without any postoperative complications and with satisfactory healing with total disappearance of the lesion after one year.
