Resolution of Odontogenic Sinus Pathosis by Endodontic Microsurgery

Abstract


A case report is presented, in which a tooth with a chronic apical abscess that has caused a maxillary sinusitis was treated with an endodontic microsurgery. A 65-year-old female patient reported discomfort in a maxillary tooth gingiva. Clinically, a dental metal-ceramic bridge with adequate marginal adaptation, involving teeth from maxillary right canine to maxillary right second molar, was observed. The periapical radiograph showed the adequate adaptation of the crown and post in the maxillary right first premolar, an apical lesion, and the heavy thickening of the maxillary sinus floor mucosa. The diagnosis established in the maxillary right first premolar was of a previously treated tooth and a chronic apical abscess. Considering the accurate fixed prosthesis adaptation and the impossibility of disassembling the five-piece-metal-ceramic bridge to perform a new endodontic treatment and the prosthetic restoration, an endodontic microsurgery of this tooth was performed. The post-treatment follow-up of 12-month recall showed a normal thickness sinus membrane and a regenerating cortical bone. The proposed microsurgery has enabled the maintenance of the existing prosthetic rehabilitation of the tooth that caused the sinus pathosis.
