A 29-year-old white woman presented with pain and swelling of the left cheek that had begun a few months before. Thirteen years earlier, a surgeon in an outside hospital had enucleated a radicular cyst (apical inflammatory cyst) in the same area. The patient's medical and family histories were noncontributory. A head and neck examination revealed no abnormalities other than the swelling of the left cheek, with mild fever and purulent drainage at the upper left posterior oral vestibule. Cortical perforation, along with pain and tenderness, was found during the intraoral palpation. All neighboring teeth were vital, and other dental abnormalities were absent.
