Storage Media for Avulsed Tooth-A Review

Abstract

Avulsion is a complex injury affecting the pulp, periodontal ligament and the alveolar bone. Avulsed permanent teeth can survive following replantation. Viable periodontal ligament (PL) cells are required for PL healing of avulsed teeth following replantation. If immediate replantation cannot be accomplished, the ability of PL progenitor cells to reproduce (clonogenic capacity) and recolonize the wound may be extended by prevention of desiccation and storage in physiological media. The present review discusses the various available storage media for avulsed teeth and their potential maintenance of the vitality of periodontal ligament cells. The choice of storage medium for preserving traumatically avulsed teeth is important for the success of future replantation.
