A radiolucent lesion adjacent to the roots of the mandibular right first and second premolars

A distinct odontogenic cyst of developmental origin, the lateral periodontal cyst has characteristic clinical, radiographic, and histopathologic findings. In addition to inflammatory lesions, lateral periodontal cysts may appear similar radiographically to an ameloblastoma or odontogenic keratocyst in its early stage; therefore, clinical and histologic correlations are necessary to establish the diagnosis and ensure proper treatment.
