“Radiographic demonstration of association of ubernaculum Dentis (Gubernaculum tract) in odontogenic cysts and tumors”-A CBCT finding

Spectrum of lesions that occur in the jaws have a cyst-like radiographic appearance. These lesions may be odontogenic or non-odontogenic and are often difficult to differentiate them on the basis of their clinical, radiographic features alone. Among odontogenic lesions without mineralization, ameloblastomas, odontogenic keratocysts, and dentigerous cysts can all appear as well-defined, unilocular, well-corticated, lucent lesions that can mimic with non-odontogenic cysts and tumors like nasopalatine duct cyst, aneurysmal bone cyst, central giant cell granuloma, hemangioma and so on. So understanding the pathogenesis of these lesions become the most imperative criteria for determining the additional investigations and treatment protocol. We hereby discuss 8 diagnosed cases of odontogenic and non-odontogenic jaw lesions, which were retrospectively visualized in cone beam computed tomography (CBCT), and an association of gubernaculum tract (cord) with odontogenic origin lesions was demonstrated.
