Core Tip

Core tip: Autotransplantation of a premolar to the anterior region has a success rate of more than 90% if the donor tooth has a developing root and pulp healing occurs. The only negative outcome is total obliteration of the pulp. This case report describe an autotransplantation of a lower first premolar with only a third of root length to the incisor area after a dental trauma that caused root resorption of a permanent upper left incisor, in a 8-year-old boy. Follow up of 15 mo showed full root growth and periodontal healing with normal mobility and obliteration of the pulp. The crown was restored using composite material to resemble the adjacent incisor. This case report shows that even with very short donor root length, autotransplantation to the anterior region can be performed in young children.
