Cemento-Osseous Dysplasia of the Maxilla Treated with Subtotal Maxillectomy

Abstract

Cemento-osseous dysplasias are non-neoplastic, reactive fibro-osseous lesions of tooth-bearing areas. Lesions in anterior mandible and localised only a few adjacent teeth termed as periapical cemento-osseous dysplasia or limited lesion occurring in a posterior jaw quadrant called focal cemento-osseous dysplasia are the same lesions. A 47-year-old male patient was complaining of flux after extraction of a tooth. A panoramic radiograph displayed lobular, irregularly shaped radiopacities involving right maxilla extending from the maxillary alveolus to the inferior orbital border and right maxillary tuberosity. Microscopic examination showed unencapsulated, extensive irregularly shaped cementum-like calcifications continious with normal bone lamella and in fibrous tissue.
