Maxillary Sinusitis of Endodontic Origin

The roots of the maxillary posterior teeth are often close to the maxillary sinus, with just a few millimeters of bone to no bone separating the root apices from the sinus mucosal tissue. This can lead to sinusitis caused by an underlying endodontic infection or a necrotic tooth.

In this CDA Oasis discussion, Dr. Mary Dabuleanu, an endodontist from North York, Ont., talks about the causes, clinical symptoms, and treatment of maxillary sinusitis of endodontic origin and presents two case studies from her practice.

“It is critical to provide appropriate treatments and avoid recurrent sinusitis despite antibiotic therapies, steroid use, as well as failure of surgical therapies such as endoscopic sinus surgery.”
