Intentional replantation of periodontally involved and endodontically mistreated tooth

Abstract

This article presents a case in which a tooth was intentionally replanted after it was endodontically mistreated; there was also a severe periodontal involvement. The unusually long period of time that the tooth survived might be attributed to a different approach to the replantation technique, such as occlusion adjustment prior to replantation, preoperative reduction of oral cavity bacteria and of the harmful aerosols commonly found in the dental operatory, placement of a noneugenol periodontal packing under the acrylic splint to prevent residual liquid monomer from seeping into the periodontal space, use of the patient's own blood and no other material to moisten the root while it was out of the socket, a short extraoral period, loose splinting, complete isolation of the operative site in the oral cavity, and completion of periodontal therapy before intentional replantation.
