Clinical Findings

Panoramic radiograph demonstrated a large and destructive radiolucency of the left posterior maxilla.  Teeth #s 12 and 13 show evidence of resorption.  The lesion involves the maxillary sinus and is displacing teeth (Figure 1).  Clinical examination revealed a large swelling expanding the buccal and palatal bone in the area; it also revealed the mobility of teeth #s 12-14.
