Trauma to the teeth is often encountered in pediatric dentistry clinical settings. However, there are few reports of treatment for dental trauma in children with disabilities or the long-term prognosis of such trauma. The authors encountered a child with Down syndrome for whom they replanted the avulsed right maxillary central incisor. The child also exhibited congenitally missing teeth, short roots, and other dental features specific to the syndrome. Although conditions were not conductive for stabilizing the replanted tooth, 3 weeks of stabilization using a wire and adhesive resin cement was performed in light of the adequate conditions. Four months after replantation, pulpal necrosis of the replanted tooth was noted, for which apexification was immediately performed. Seventeen months after replantation, the apex of the replanted tooth was confirmed to be sealed with hard tissue. The root canal was therefore filled with gutta percha points and the patient attended follow-up examinations every 3 to 4 months thereafter. Three years after replantation, percussion sounds produced by the affected tooth were sharp and clear, and its physiological mobility had disappeared. Tooth ankylosis was therefore deemed to have been achieved. No replacement resorption of the replanted tooth has been seen during the subsequent 10 years.
