Cysts of the mandible and maxilla.

Mandibular and maxillary cysts originate from elements of the teeth (odontogenic), or from epithelial remnants trapped in fusion lines during development (nonodontogenic). Both types can be clinically asymptomatic and must be treated surgically. The specific diagnosis of a jaw cyst and its recurrence depends upon the anatomical location, the radiographic appearance, and the pathological diagnosis.
