Avulsion is one of the most complex kinds of trauma that was believed to result in pulp necrosis and therefore require endodontic treatment. This case demonstrates that in avulsion of immature permanent incisors we should consider the revascularization before starting endodontic treatment. Avulsion of an immature permanent central incisor in a 6 and a ½-year-old girl is presented. The girl was brought immediately to a dental offi ce, and the immature tooth was replanted shortly after the avulsion. During 3 years follow-up, continuation of root development, pulp revascularization and bone-like tissue growth into the pulp chamber were observed. The tooth is vital and asymptomatic with no signs of ankylosis.
