<unk> s can occur at any age, however they are more common in the third to sixth decades. The male to female ratio is approximately 2:1. The majority are found in the mandible, with half occurring at the angle of the mandible. Early<unk> s usually do not display symptoms. Typically, clinical signs and symptoms present with bony expansion, or infection. However, bony expansion is uncommon as<unk> s grow due to increased epithelial turnover rather than osmotic pressure. When symptoms are present they usually take the form of pain, swelling and discharge due to secondary infection.<unk> s are usually noted as incidental radiographic findings. Radiographically they can be seen as unilocular or multilocular radiolucencies. They can be mistaken for other cysts such as residual cysts or a dentigerous cyst if they occur over an unerupted tooth. Relative incidence of<unk>  cysts.<unk>  is labeled at bottom right.
