Lateral Periodontal Cyst
Definition: A cyst that forms lateral to a vital tooth. These are commonly incidental findings.
Location: Most commonly found between the mandibular lateral incisor to second premolar. In the maxilla, most commonly found near the lateral incisor.
Edge: Well-defined. Corticated.
Shape: Round to ovoid.
Internal: Radiolucent, unilocular. A multilocular lateral peridontal cyst is referred to as a botryoid odontogenic cyst.
Other: The size is typically less than 1 cm in diameter. This may obliterate the lamina dura of the adjacent teeth. It may displace or resorb adjacent teeth as it enlarges.
Number: Typically single, but may be multiple (uncommon).
