CBCT Diagnosis of a Stafne Bone Defect.

The Stafne bone defect, also known as the Stafne bone cyst, or Stafne bone cavity, is an asymptomatic, static depression of the lingual aspect of the mandible that often appears as a radiolucent area near the angle of the mandible. It noted as an incidental finding during routine dental imaging. The purpose of this article is to present a case that was diagnosed as a Stafne bone defect using Cone Beam Computed Tomography (CBCT). This diagnosis is based on radiographic characteristics, which are described as a well-defined, round to ovoid radiolucent lesion in the lower left mandible, located below the inferior alveolar nerve canal and anterior to the angle of the mandible. Radiographic confirmation should preclude further surgical exploration.
