An Interesting Solid Mass in the Posterior Maxilla of a Pregnant Woman

Abstract

We report a case of a 22 year-old pregnant woman who was considered in the differential diagnosis included an erupted odontoma and an exposed necrotic bone of the maxilla at the time of the third trimester. During the 4^th week of the postpartum period, an orthopantomography was taken and radiopaque mass and ill-defined impacted molar teeth were observed. After the surgical operation, the final diagnosis of ossifying fibroma was rendered. Ossifying fibromas behave like benign bone neoplasms and are often considered to be a type of fibro-osseous lesions. They can affect both the mandible and the maxilla, particularly the mandible. Fibroosseous lesions with unusual clinical and radiological presentations might disquieten both the dental practicioner and the patient.
