AUTHORS: Dr. Shalini Singhal Senior lecturer Dr. Hirak Bhattacharya Reader Dr. Manvi Agarwal Senior Lecturer Department of Periodontics Institute of Dental Sciences, Bareilly ABSTRACT LATERAL PERIODONTAL CYST is a rare odontogenic cyst of developmental origin. It occurs on the lateral periodontal region of a vital tooth and has specific histologic features. In this paper a case of a lateral periodontal cyst is presented. A variety of cysts, odontogenic or not, may develop in a lateral periodontal area of a tooth. Such cysts are mainly the odontogenic keratocyst, the inflammatory periodontal cyst which has developed from an infected lateral accessory root canal or from infection through the gingival crevice, the nonodontogenic globulomaxillary cyst, and the incisive canal cyst. The lateral periodontal cyst is an uncommon but well recognized type of developmental odontogenic cyst. It occurs in the lateral periodontal region of a vital tooth and has specific histologic features. It is usually asymptomatic and is discovered on routine radiological examination of the teeth, although an obvious swelling may be seen occasionally on the labial surface of the gingiva.
