| ==Overview==
| |
| '''Traumatic bone cyst''', also called a '''simple bone cyst''', is a condition of the [[jaw]]s. 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 [[physical trauma|trauma]]. It appears on [[radiograph]]s as a well-circumscribed radiolucency (dark area), and it commonly scallops between the roots of [[teeth]]. When the lesion is [[surgery|surgically]] opened, an empty cavity is found.
