Abstract:

Odontogenic cysts are by far the most common cysts of the jaws. A radicular cyst is a cyst that most likely results when rests of Malassez epithelial cells in the periodontal ligament are stimulated to proliferate and undergo cystic degeneration by inflammatory products from a nonvital tooth. Radiographically, their periphery usually have a well-defined border and their internal structures are radiolucent. In order to make definite radiological diagnosis, more than one projection methods may be needed. The aim of this report is to present a case with an unusual location of radicular cyst caused by a molar root which was left after a tooth extraction procedure and accompanied by reactive bone development.
