Lateral periodontal cyst

Abstract

The lateral periodontal cyst (LPC) is a harmless developmental aberration derived from odontogenic epithelia lying between the roots of vital teeth. The exact histogenesis of LPC is a matter of debate but therapy is usually only required to maintain stable periodontal conditions and in case of evidence for growth of the cyst. We report on a case of LPC where successful surgical therapy had initialized osseous restoration. We further discuss the value of histological findings to substantiate a clinical and radiological diagnosis.
