Cemento-osseous dysplasias are a group of disorders known to originate from periodontal ligament tissues and involve, essentially, the same pathological process. They are classified depending on their extent and radiographic appearances, into three main groups: periapical (surrounds the periapical region of teeth and are bilateral), florid (sclerotic symmetrical masses) and focal (single lesion) cemental dysplasias. Florid cemento-osseous dysplasia (FCOD) is a type of fibro-osseous lesion and represents a reactive process in which normal bone is replaced by poorly cellularized cementum-like materials and cellular fibrous connective tissues. It is strictly localized to the tooth-bearing or edentulous areas, often occurring bilaterally with symmetric involvements. FCOD has also been classified as gigantiform cementoma, chronic sclerosing osteomyelitis, sclerosing osteitis, multiple estenosis and sclerotic cemental masses. Radiographically, it appears as a dense, lobulated masses, often symmetrically located in various regions of the jaws and patients do not have laboratory evidence. Cone beam computed tomography, because of its ability to give axial, sagittal, and frontal views, is useful in the evaluation of these lesions. The best management for the asymptomatic FCOD patient consists of regular recall examinations with prophylaxis. This article reports the case of a middle aged female patient who was diagnosed with FCOD on the basis of clinical, radiographic, biochemical and histological findings.
