Stafne's bone cyst (SBC) are static lesions that are commonly located at the angle of the mandible. Males are affected more as compared with females with an incidence ranging from 0.10% to 0.48%. Stafne bone cysts are usually asymptomatic. Panoramic radiograph of the cyst shows a well-defined radiolucency on the left side of the mandible which lies below the inferior alveolar canal. These lesions are detected easily with routine intraoral radiographs, as these lesions are usually present at particular sites with a clear demarcation from the surroundings. Cone-beam computed tomography (CBCT) is a useful diagnostic tool that helps to confirm its diagnosis. This article describes the incidental finding in a 55-year-old male patient incidentally when patient was advised for intraoral radiography during a routine dental checkup. The patient was advised orthopantomograph in which an oval cystic lesion was evident. For a clear diagnosis, the patient was referred for the CBCT, which confirmed the presence of SC which is benign and radiographically seen as a unilocular lesion.
