Dental osteoma radiology

Is osteoma radiolucent?
Cortical osteoid osteoma is the classic type of the disease consisting of a small central nidus, usually radiolucent, associated with perifocal dense bone..
What are the radiographic features of osteoma mandible?
The peripheral osteoma of the jaw is uncommon.
Radiographically, peripheral osteomas are seen as oval radiopaque well-circumscribed masses attached to the cortex by a broad base or a pedicle.
Three theories have been proposed: developmental, neoplasic and reactive..
What imaging is used for osteoma?
Imaging of Osteoid Osteoma
Imaging usually is very typical: X-rays show new bone formation and sometimes a small lucent spot (smaller than 1.5 cm), which is defined as the nidus.
Computed tomography (cat scan, CT) is even better suited to show the new bone formation and the nidus..
What is a osteoma in dentistry?
Osteomas are benign osteogenic neoplasms caused by proliferation of mature compact or cancellous bone.
Clinically they may be classified as peripheral, central or extraskeletal.
Osteomas usually involve the craniofacial region with mandible being the most common site..
What is dental osteoma?
Osteomas are benign osteogenic neoplasms caused by proliferation of mature compact or cancellous bone.
Clinically they may be classified as peripheral, central or extraskeletal.
Osteomas usually involve the craniofacial region with mandible being the most common site..

What is the oral differential diagnosis for osteoma?
The differential diagnosis of osteomas include exostoses, osteochondroma, osteoid osteoma, periosteal osteoblastoma, parosteal osteosarcoma, peripheral ossifying fibroma, Paget's disease, fibrous dysplasia, and odontoma..
What is the radiographic appearance of osteoma?
Radiographic features
Osteomas appearing ivory-like as round, very radiodense lesions, similar to the normal cortex ⁵.
Mature osteomas may demonstrate central marrow ^ref..
Osteomas are benign osteogenic neoplasms caused by proliferation of mature compact or cancellous bone.
Clinically they may be classified as peripheral, central or extraskeletal.
Osteomas usually involve the craniofacial region with mandible being the most common site.
Osteomas are benign, slow-growing osteogenic tumors commonly occurring in the craniofacial bones.
Osteomas are characterized by the proliferation of compact and/or cancellous bone.
It can be of a central, peripheral, or extraskeletal type.
Radiographic features

Terminology

Osteoma is the preferred terminology with ivory exostosis, parosteal osteoma

Diagnosis

Diagnostic criteria according to the WHO classification of soft tissue and bone tumors (5th edition) 5: 1

Clinical Presentation

These lesions are benign, slow growing, and usually asymptomatic. They may be incidentally identified as a mass in the skull or jaw

Pathology

Osteomas are benign osteogenic tumors composed of lamellar/cortical-type bone. The etiology is unknown 5

Radiographic Features

Osteomas appearing ivory-like as round, very radiodense lesions, similar to the normal cortex 5

Treatment and Prognosis

Osteomas are benign and only require excision if they cause adjacent complications (e.g

Differential Diagnosis

Considerations include many cranial and facial bone lesions 6: 1. exostosis 2. cemento-osseous dysplasia 3. Paget disease 4

How is peripheral osteoma of the mandible diagnosed?

Hence a final diagnosis of peripheral osteoma of the mandible was considered

Panoramic radiograph revealing the radiopaque lesion

Occlusal radiograph showing the broad base of the bone mass and location of the lesion

Osteomas real prevalence is unknown, with no sex predilection

What is occlusal radiograph of a mandibular osteomas?

Occlusal radiograph showing the broad base of the bone mass and location of the lesion

Osteomas real prevalence is unknown, with no sex predilection

However mandibular osteomas are rare entity

1 Osteomas are usually asymptomatic, characterised with slow and continuous growth patterns

What is the etiology of mandibular osteomas?

Mandibular osteomas exhibit a site predilection for the angle and lower border of the body of mandible (mostly in association with the buccal cortical plate)

Involvement of the lingual aspect of mandibular body, such as in our case, is an uncommon occurrence [ 6, 12, 19, 20 ]

Etiology of osteomas is still controversial
