Value and limitation of panoramic radiography in the diagnosis of maxillary sinus pathosis.

Panoramic radiography is, however, not a technique for the examination of cloudiness, and thickening of the mucous membrane of the maxillary sinus, and bony sclerosis of the maxilla associated with maxillary sinusitis. The two techniques supplement each other in the diagnosis of maxillary sinus pathosis.
