What is a traumatic bone cyst?

The traumatic bone cyst (TBC) is an uncommon nonepithelial lined cavity of the jaws. The lesion is mainly diagnosed in young patients most frequently during the second decade of life. The majority of TBCs are located in the mandibular body between the canine and the third molar.

Is traumatic bone cyst a true cyst?

Despite its name, this lesion has no epithelial lining and does not represent a true cyst. The cause of simple bone cysts is uncertain. The synonymous term traumatic bone cyst is based on a theory that the lesion may arise secondary to a traumatic event that causes intrabony hemorrhage.

Is traumatic bone cyst a Pseudocyst?

The traumatic bone cyst, an uncommon lesion of the jaws, belongs to the category of ‘pseudocyst’ owing to its lack of a lining epithelial membrane.

How is a traumatic bone cyst treated?

The traumatic bone cyst is usually successfully treated by surgical exploration and curettage of the walls of the bony cavity.

What does it mean to have a traumatic bone cyst?

Traumatic bone cyst, or simple bone cyst, is a pseudocyst that represents a bony dead space. Although trauma is suspected to be the cause, this has not been proved. The lesion is believed to develop from abnormal healing of hemorrhage within bone. The natural history has not been elucidated,…

Can a traumatic bone cyst of mandible be diagnosed?

This lesion is particularly asymptomatic and therefore is diagnosed by routine dental radiographic examination as a unilocular radiolucency with scalloped borders, mainly in the posterior mandibular region. The exact etiopathogenesis of the lesion remains uncertain, though it is often associated with trauma.

What is the natural history of a bone cyst?

The lesion is believed to develop from abnormal healing of hemorrhage within bone. The natural history has not been elucidated, but it is suspected that these lesions are capable of resolution without surgical intervention. Nonetheless, exploration is usually performed to rule out other more significant lesions.

How are traumatic bone cysts related to osseous dysplasia?

Inter-radicular scalloping of varying degrees is characteristic, and occasionally slight root resorption may be observed. Traumatic bone cysts have often been seen in association with florid osseous dysplasia. The relationship between these two entities is not understood.
