Differentiating maxillary sinus pain from pulpal etiology is one of the more difficult diagnostic challenges facing clinicians. In addition, the pathological extension of dental disease into the maxillary sinus and its sequelae often are unrecognized in clinical medical and dental practice. This lecture explains and illustrates the etiology and symptoms of acute and chronic rhinosinusitis and its similarities, distinguishing differences, and frequent inter-relationship with endodontic etiology. The goal is to help practitioners recognize a maxillary sinusitis of dental origin and relieve patient discomfort through accurate diagnosis, appropriate treatment, and communication with ENT specialists when necessary. Emphasis is also made on the enhanced diagnostic and treatment advantages of cone beam CT imaging. The increased sensitivity of CBCT in detecting canal anatomy, periapical lesions, root form and sinus mucosal changes has fundamentally transformed endodontic decision making and the delivery of care.
