Anterior stafne defect of the mandible

Abstract

Stafne bone cavity is round or ovoid, well circumscribed radiolucency located at the lingual cortex of mandible, below the inferior alveolar canal, mostly near the angle. Anterior location of Stafne bone cavity is a unusual developmental anomaly and only 66 cases reported in the English literature. As a result of the localization of this formation, which is asymptomatic and diagnoses with routine radiographic examination, it may be confused with pathologies and may cause misdiagnosis. In this case report a Stafne bone cavity located in the mandibular incisor-canine region, which was found incidentally during radiographic examination cavity is presented with cone beam computed tomography and magnetic resonance images.
