Retrieval of separated instrument lodged in the extraradicular region using looping device - A report of two cases.

Intracanal separation of endodontic instruments is a common iatrogenic error that can be successfully managed by various instrument retrieval techniques. However, separation in an aberrant perforation site occurs rarely and it is challenging to assess and retrieve. This report of two cases elaborates the successful retrieval of extraradicularly separated instruments using a looping device in difficult clinical scenarios. The teeth were subsequently restored to function with the aid of dental operating microscope, diode laser, and deep margin elevation followed by suitable postendodontic rehabilitation.
