Antral aspergillosis has recently been found to be often induced by endodontic material (Endomethasone, N2, Riebler Material), that contains zinc oxide and paraformaldehyde. A study of 34 otherwise healthy patients with aspergillus infection of the maxillary sinus had a pathognomonic radiologic appearance noted in 26 patients (76%). All patients except one had a history of endodontic therapy. The radiology, pathogenesis, differential diagnosis, treatment, and prevention of solitary antral aspergillosis are briefly discussed.
