Is dentigerous cyst unilocular or multilocular?

The radiographic appearance of a dentigerous cyst is usually that of an unilocular, non-expansile radiolucency characterized by well-defined borders and is always associated with the crown of an impacted tooth, most often a third molar. Dentigerous cysts range in size from 5mm to 7cm or even larger.

Can dentigerous cysts be multilocular?
