Healing following avulsion and replantation is dependent on the extent of pulpal and periodontal ligament (PDL) tissue damage. Therefore, immediate replantation is the recommended treatment of choice for an avulsed permanent tooth. To achieve a more favourable prognosis following tooth replantation, use of an appropriate interim transport medium is usually advocated. Numerous studies have researched and advocated the use of media like saliva, milk, Hank's Balanced Salt Solution (HBSS) and ViaSpan. However, current research has indicated the use of few newer media as promising interim transport media for an avulsed tooth. This review summarises the current developments regarding the introduction of newer interim transport media for the treatment of avulsed teeth.
