Surgical endodontics of upper molars: relation to the maxillary sinus and operation in acute state of infection.
Findings in 200 cases of root resection of first maxillary molars showed perforation to the sinus in half of the cases. In 42% of the cases, the first maxillary molar had root resection performed in a subacute or acute state of infection. Only two cases developed postoperative sinusitis. Antibiotic treatment was indicated preoperatively in 3% and postoperatively in 5%. Postoperative symptoms, such as pain and swelling, were usually moderate, possibly because of a nontraumatizing operation technique, a careful removal of infected tissue, and a good drainage by loose suturing.
