Storage Medium for Avulsed Tooth

Traumatic Dental Injuries (TDI) represents one of the most common reasons for emergency appointments in dental practice. Dental avulsion is a traumatic injury characterized by the complete displacement of the tooth from its socket. The trauma that leads to a tooth avulsion causes damage to the cementum, periodontal ligament, alveolar bone, neurovascular supply to the pulp and the surrounding gingiva. Immediately after injury, the periodontal ligament (PDL) and pulp in the avulsed tooth begin to suffer ischaemic injury, which is soon aggravated by drying, exposure to bacteria or chemical irrigants. Incidence of tooth avulsion is approximately 0.5-16% of traumatic injuries in the permanent dentition. It occurs most often in the age group of 7-10 years, when the alveolar bone is resilient and offers minimal resistance to extrusive forces.The proposition of this book is to present a review of literature on various storage media that has been investigated so far in maintaining the viability of periodontal ligament cells and to update the knowledge in recent advances in Storage medium.
