Figure 7 Dentigerous cyst. A 51-year-old man with 6-month history of jaw swelling and liquid intermittently draining into his mouth. A-C: Orthopantomogram (A), axial (B), and sagittal (C) computed tomography images reveal large unilocular cystic lesions in the bilateral mandibular bodies (arrows) centered at the crown of unerupted molar teeth (arrowheads), characteristic features of the dentigerous cyst. The lesions expand along the longitudinal axis (i.e., anteroposterior dimension) of the mandible, with focal bone dehiscence in multiple areas (dashed arrows). Patient underwent surgical resection, with pathologically confirmed dentigerous cysts.
