RESUMEN
Intentional re-implantation is a procedure in which a tooth is intentionally extracted and then reinserted into its own socket for various treatment modalities. In this case report, we discuss a case of intentional re-implantation as a treatment option for failed root canal treatment with broken instrument in the apical 1/3rd of a maxillary first molar. A follow up for 2 year revealed the patient to be asymptomatic, the tooth to be sound and functional with no evidence of root resorption.
RESUMEN
The fracture of an endodontic instrument is an obstacle in completion of a routine successful pulp space therapy. Ni-Ti instruments corrode when in contact with sodium hypochlorite which leads to their deterioration and ultimately fracture during use. Removal of separated instrument from root canal is often a very difficult procedure. This procedure is more complicated when the instrument separated is closer to the mandibular canal. A case is presented in which a separated hand instrument was retrieved from the mesio buccal of a second molar approximating the mandibular canal root by replantation.
