Orbital pain and headache secondary to overfilling of a root canal

Abstract

A 35-yr-old woman was referred to the Istanbul University, Faculty of Dentistry, Oral Surgery Department with complaints of orbital pain and headache. Panoramic radiographs showed overfilling of a maxillary premolar, which caused a perforation in the maxillary sinus floor. The etiology, clinical manifestations, and treatment of this complication are discussed with emphasis on early surgical intervention to decrease the risk of a superimposed aspergillosis infection.
