The occurrence of osseous, fibrous, and fibro-osseous lesions in the jaw bones might pose challenges for accurate diagnosis and the selection of the best therapeutic approach. Certain radiolucent, radiopaque, or mixed-origin lesions can look very similar to other bone lesions, because of the stages of their growth, calcification, maturation, and possible local factors affecting the lesion. Ossifying fibroma (OsF, OF) is a type of fibro-osseous lesion, whose radiological characteristics might sometimes be uncertain. It may appear on classic radiographs and cone beam computed tomography as a radiolucent/radiopaque lesion with calcification bodies or a shape with a cloud-like appearance. The appearance is mostly related to the lesion’s maturation level, calcification stage, and number of fibrous elements. Diagnosis might be challenging. Its histopathological evaluation reveals a combination of mineralized and fibrous connective tissues in the mass. From a radiological point of view, because of the tumor’s various stages of bone remodeling, formation, and resorption, diagnosis might be troublesome. Different diagnoses should include cemento-osseous dysplasia, fibrous dysplasia, or cementoblastoma. A biopsy could provide an accurate histopathological examination, improving diagnosis and influencing later surgical approaches. Regardless of the final specimen evaluation, surgery is the treatment of choice. The authors would like to present the correlation between radiological and histopathological data in tumor treatment outcomes. Full article

The purpose of this study is to report a case of idiopathic osteosclerosis of the mandible and to discuss the differential diagnosis of this lesion. A 17-year-old female was referred to the University Hospital of Geneva by her orthodontist following the fortuitous finding of a radio-opaque lesion in the right posterior mandible at the apex of tooth 44. Intraoral clinical examination revealed no abnormalities of the oral mucosa. Tooth 44 was asymptomatic and reacted positively to the sensitivity test. The orthopantomogram revealed a well-defined unilocular radiodense lesion, surrounded by a thin radiolucent border, measuring 10 × 33 mm, located in the IV quadrant, related to the apex of tooth 44. Differential diagnoses mainly included cementoblastoma, focal cemento-osseous dysplasia, ossifying fibroma, condensing osteitis and idiopathic osteosclerosis. The biopsy material allowed a diagnosis of idiopathic osteosclerosis. The proposed treatment was therefore a “wait and see” approach. After 2 years of follow-up, the patient was asymptomatic, and healing was complete without any neurosensory complications. Our case underlines the differential diagnosis complexity of radio-opaque lesions associated with teeth. Full article

Background. Mineralized lesions of the jaws are often found incidentally on radiographs and computed tomography. Most of them are benign, and only a few rare cases are associated with malignant transformation. However, there is little clinical data on successful rehabilitation with implants in patients with mineralized lesions. This narrative review aimed to study the efficiency and safety of dental implantation in the area of hyperdense lesions. Materials and Methods. A PubMed, Google Scholar, and Science Direct database search was carried out with keywords and manually. Results. The literature exploration identified 323 articles; only 19 of them matched the search criteria and reported cases about dental implantation in the lesion area. It has been shown that in 84.2% of described cases, dental implantation was successful: in the osteoid osteoma, odontoma, cementoblastoma, idiopathic osteosclerosis, and condensing osteitis areas dental implantation was performed without any complications. The possibility of lesion recurrence and implant failure limited the use of dental implants in the area of osteoblastoma and cemento-osseous dysplasia. Although most cases of dental implantation in hyperdense jaw lesions were successful and were not accompanied by complications, further research is needed. Full article

Benign osteoblastoma (OB) is a rare tumor of bone representing less than 1% of all tumors of the maxillofacial region. Vertebral column, sacrum, long bones, and calvarium are more frequent sites of this tumor. Clinically, patients present with pain and swelling. Histologically, contain a well vascularized, osteoblastic connective tissue stroma and occasionally, osteoclasts along with osteoid and varying degrees of calcification, as well as immature bone may also be noted. The main aim of this report is present a case of OB occurring in the mandible and a brief review of English Medical Literature of this tumor. Many bone-producing lesions possess some overlapping clinical, radiographic or histopathological findings similar to osteoblastoma. Understanding and correlating all features helps in correct diagnosis and adequate management of this rare entity. Hence, osteoblastoma has to be differentiated from other bone lesions for correct diagnosis. Full article
