The lateral periodontal cyst is a cyst that arises from the epithelial rest of Malassez which is a remnant from odontogenesis. It is more common in middle-aged adult males. Usually there is no pain associated with it and it usually appears as a unilocular radiolucency (dark area) on the side of a canine or premolar root. Commonly seen in mandibular bicuspid area. Microscopically the lateral periodontal cyst appears the same as the gingival cyst of the adult.
