Some jaw bone conditions are “pseudo-diseases”, such as unerupted teeth, bone marrow defects, Stafne bone defect (static bone cyst), osteosclerosis, pseudocyst of maxillary sinus, or sub-pontic osseous hyperplasia. Traumatic (solitary) bone cyst arises from trauma causing intramedullary hemorrhage that subsequently leaves a radiolucency with characteristic scalloped superior margin (it rarely damages teeth) (Figures 56.1a and b). Bone diseases that may affect the jaws are described below.

Non-neoplastic diseases

  • Osteonecrosis. Osteoradionecrosis (ORN) and bisphosphonate-related osteochemonecrosis of the jaws (BRONJ) are uncommon complications of radi/>
