Avulsed Tooth - A Storage Medium Dilemma an Update

Avulsion injuries deal with exarticulation or total luxation of the tooth out of its socket as a result of a blunt impact on the tooth due to contact sports, road accidents or fights which leads to severance of the neurovascular pulpal supply, separation of the PDL and exposure of the root surface (oral/extra-oral environment contaminated with microorganisms) [1,2]. The success of a replanted tooth depends upon the extra oral time of tooth out of its socket and its replacement in the socket, the viability of the periodontal ligament (PDL) cells, condition of the tooth and cementum and amount of bacterial load leading to complications like surface resorption, inflammatory resorption and replacement resorption/ankylosis [3].
