Classification and external resources

Idiopathic osteosclerosis is a condition which may be found around the roots of a tooth. It is usually painless and found during routine radiographs. It appears as a radiopaque (light area) around a tooth, usually a premolar or molar. There is no sign of inflammation of the tooth.

Presentation[edit]

Focal radiodensity of the jaw which is NOT inflammatory, dysplastic, neoplastic or a manifestation of a systemic disease. This is common and affects 5% of the population, usually seen in teens and those in their 20's. Typically asymptomatic and is an incidental finding on a radiograph. found anywhere in the jaw, most commonly in the mandibular premolar-molar region. The shape ranges from round to linear streaks to occasional angular forms.

Cause[edit]

A reaction to past trauma or infection but it's difficult to rule out in some cases.

Diagnosis[edit]

Usual diagnosis is via radiograph, patient history, biopsy is rarely needed. Periodic follow ups should included additional radiographs that show minimal growth or regression.

Radiology[edit]

Well defined, rounded or triangular radiodensity, that is uniformly opaque. There is no lucent component. Found near the root apex or in the inter-radicular area. Root resorption and tooth movement are rare.

Differential Diagnosis[edit]

Condensing osteitis, sclerosing osteomyelitis, cementoblastoma, hypercementosis, Exostoses (tori). Condensing osteitis may resemble idiopathic osteosclerosis, however, associated teeth are always nonvital in condensing osteitis.

Treatment[edit]

No treatment is necessary.
