Fibrous dysplasia is a kind of benign bone lesion characterized by the manifestation of the replacement of the normal substance of bone by fibro-osseous connective tissue. A patient diagnosed fibrous dysplasia had unbearable pain in the left mandibular region only. To treat the patient, an navigation template was designed to guide the decompression of inferior alveolar nerve, and piezosurgery w...

Objectives: Fibro-osseous lesions of the craniofacial complex comprise of a diverse, interesting and challenging group of conditions that pose difficulties in classification and treatment. The two most confused benign fibro-osseous lesions are fibrous dysplasia and ossifying fibroma. Sometimes, the classic clinical, radiologic or pathologic features of fibrous dysplasia or ossifying fibroma may...

Fibrous dysplasia is a benign fibro-osseous lesion of the bone that commonly affects the jaws with a higher prevalence in the maxilla than the mandible. It is a lesion of unknown etiology, uncertain pathogenesis, and diverse histopathology. Fibrous dysplasia can involve multiple bones (polyostotic) or a single bone (monostotic). It represents about 2 to 5% of all bone tumors and over 7% of all ...

Florid cemento-osseous dysplasia (FCOD) has been described as a condition that characteristically affects the jaws of middle-aged black women. It usually exhibits as multiple radiopaque cemetum-like masses distributed throughout the jaws. Radiographically, FCOD appears as dense, lobulated masses, often symmetrically located in various regions of the jaws. Computed tomography, because of its abi...

Periapical cemento-osseous dysplasia (PCOD) is a rare benign lesion, often asymptomatic, in which fibrous tissue replaces the normal bone tissue, with metaplasic bone and neo-formed cement. We present a rare case of mandibular PCOD in a woman of 55 years, who presented with moderate swelling and mobility of teeth 32-33-34. Endoral radiography showed that these teeth had been devitalized; they h...

Cemento-osseous dysplasia is a disorder typically found in middle-aged black women. However, the present report describes a case in a 61-year-old Vietnamese male. Without proper pulp testing and diagnosis, the radiographic presentation can easily be misdiagnosed as periapical periodontitis. On the basis of pulp vitality, lack of clinical symptoms and radiographic features, the diagnosis in this...

Fibrocartilaginous dysplasia is a variant of fibrous dysplasia showing extensive cartilaginous differentiation (enchondroma-like areas). The amount of cartilage varies from case to case. This has been reported more commonly in polyostotic disease. We present a 19 year old boy who presented with multifocal osteolytic lesions involving right femoral neck and lower end of left fibula. Curettage of...
