The Lateral Periodontal Cyst: A Report of 37 Cases

Abstract

The lateral periodontal cyst is a developmental cyst of odontogenic origin which is located along the lateral aspect of a tooth root. Thirty-seven previously unreported lateral periodontal cysts ( LPCs ) are presented. Clinical, roentgenographic and histologic features of the LPC are reviewed. Further, the importance of distinguishing the developmental LPC from laterally positioned inflammatory cysts of pulpal or periodontal disease origin and laterally occurring odontogenic keratocysts is stressed.
