Lateral Periodontal Cyst: A Report of Two Cases with Varying Clinico-Radiological Features

Lateral periodontal cyst (LPC) is an uncommon type of odontogenic cyst of developmental origin that typically occurs laterally on the root surface of a tooth, representing 0.8% - 2% of cysts in the jaws. They are frequently located in the mandibular premolar area followed by the anterior region of the maxilla. It is usually asymptomatic and is discovered on a routine radiograph. The involved teeth are usually vital. Although the occurrence of lateral periodontal cyst is rare, the precision of its diagnosis is necessary so that the correct treatment can be established. The purpose of this article is to report two cases of lateral periodontal cyst, one presenting with typical clinical features while other having contrasting features and to review the relevant literature which describes the clinical, radiological and histopathological features of lateral periodontal cysts.
