We evaluated the clinical effects of the replantation of vertically fractured roots using a dentin bonding system and composite resin. Sixty-four vertically fractured posterior teeth were extracted without damage to the alveolar sockets. Root canal treatment was completed outside the mouth immediately and the fractured pieces of the tooth were bonded using Clearfil SE Bond and Clearfil AP-X (Kuraray, Japan). The occlusal surface of the bonded tooth was reduced to avoid occlussal interference. The tooth was then replanted into the socket and full coronal restoration was done two months later. Follow-up examinations were carried out at 6 months, 1 year and 2 years. Sixty of the 64 teeth were sound both clinically and radiographically 2 years after the replantation. We concluded that replantation using a dentin bonding system and composite resin is an effective treatment for vertically fractured posterior teeth.
