Repair of a root perforation with a resin-ionomer using an intentional replantation technique

The repair of a root perforation can be accomplished using different materials and techniques. When the defect is surgically inaccessible, the tooth can be carefully extracted, repaired extraorally, and placed back into the socket. This procedure, known as intentional replantation, is often a measure of last resort in an heroic effort to save a hopeless tooth. This case report describes the treatment of a tooth with an iatrogenic root perforation and the subsequent healing of the surrounding periodontium using an intentional replantation technique and resin-ionomer to repair the root defect.
