Solitary radiolucency near the angle of mandible

Stafne's Bone cavity is a radiolucent unilaterally located cavity normally present in posterior mandibular region, between the angle of mandibleand the third molar, below the mandibular canal and above the inferior border of mandible. It originates from glandular tissue pressure on the lingual cortical plate. Orthopantomograph can first identify this entity as a radiolucent image. But advanced imaging like CT should be done to confirm the diagnosis. The present article focuses to report a case of Stafne's bone cavity encountered incidentally on an orthopantomograph.
