Media for Avulsed teeth

Tooth avulsion is characterized by complete displacement of the tooth from its alveolar socket. Avulsion accounts for up to 16% of all dental traumatic injuries in the permanent dentition. Studies have revealed that the prevalence of dental traumatic injuries is increasing, ranging from 16% to 40% among 6-year old children and from 4% to 33% among 12-14-year old children. A significant proportion of dental trauma relates to sports, unsafe play grounds or schools, road accidents ,or violence. Immediate reimplantation of an avulsed tooth is the best treatment option at the site of the accident; however, this is not always possible. Studies have shown that the most critical factors affecting the prognosis of an avulsed tooth after replantation are Extra oral time, Amount of physical damage to the root surface, and the Storage medium in which the avulsed tooth is stored before treatment. Extraoral dry time and damage to the root surface are aspects that can be controlled only to a certain extent; therefore, to minimize failure after replantation, the avulsed tooth should be stored in a solution that preserves the viability of PDL cells. Recent studies have evaluated various
