Traumatic bone cyst, also called a
simple bone cyst, is a condition of the
jaws. It is more likely to affect
men and is more likely to occur in people in their first and second decades. There is no known cause though it is sometimes related to
trauma. It appears on
radiographs as a well-circumscribed radiolucency (dark area), and it commonly scallops between the roots of
teeth. When the lesion is
surgically opened, an empty cavity is found.
