The etiopathology of maxillary sinusitis of dental origin (MSDO) is well established, and chronic apical periodontitis is the second most common cause of all dental-induced sinusitis incidents. The literature presents no common treatment protocols for MSDO and very few studies address the impact of root canal treatment (RCT) in its management. The literature presents cases of maxillary sinusitis resolution after performing a multivisit nonsurgical endodontic treatment, yet none described complete healing of MSDO as a result of single-visit nonsurgical RCT. This paper reports a case series of maxillary sinusitis of endodontic origin (MSEO) associated with upper maxillary molars that were successfully treated with single-visit nonsurgical antiseptic RCT. In all cases, the clinical symptoms subsided within a week after endodontic treatment. Control cone-beam computed tomography (CBCT) scan showed healing of periapical bone and total resolution of maxillary sinusitis symptoms. MSDO treatment protocol should start with nonsurgical antiseptic RCT. Single-visit nonsurgical endodontic treatment can be effective in MSEO management. CBCT is a method of choice in MSEO diagnostics. Endodontists are well trained and well equipped to treat MSDO, and the cooperation between ear, nose, and throat specialists, maxillofacial surgeons, and endodontists is crucial for both: good diagnostics and treatment.
