Mandibular Bone Defect Imaging Features in Cone Beam Computed Tomography: A Case Report

Mandibular bone defect or Stafne bone defect is usually an incidental finding in imaging examinations due to its lack of symptomatology. It is often observed as a radiolucent lesion with well defined limits. In this report it is demonstrated a case of mandibular bone defect close to the mandible angle, in a 16-year old female, that performed cone beam computed tomography examination in order to verify the proximity of the third inferior molar to the mandibular canal. In this case, it was verified that the defect was continuous to the mandible border and it had a thick sclerotic margin. No treatment is necessary to mandibular bone defects, but regular follow-ups are strongly recommended.
