Cysts located adjacent to the root of a vital tooth
“Lateral periodontal cysts (LPCs) are defined as non-keratinised and non-inflammatory developmental cysts located adjacent or lateral to the root of a vital tooth.”[1] LPCs are a rare form of jaw cysts, with the same histopathological characteristics as gingival cysts of adults (GCA). Hence LPCs are regarded as the intraosseous form of the extraosseous GCA.[2][3] They are commonly found along the lateral periodontium or within the bone between the roots of vital teeth, around mandibularcanines and premolars.[3] Standish and Shafer reported the first well-documented case of LPCs in 1958, followed by Holder and Kunkel in the same year although it was called a periodontal cyst.[2][3] Since then, there has been more than 270 well-documented cases of LPCs in literature.[2]
