A new method for retrieving silver points and separated instruments from root canals.

A new method for the removal of metallic canal obstructions is presented. After gaining access to the coronal end of the separated instrument or silver point, a circular groove is prepared around it using ultrasonic tips. A short piece of fine stainless-steel tubing can now be pushed over the exposed end of the object. A Hedström file is pushed in a clockwise turning motion through the tube to wedge between the tube and end of the object. This produces a good interlocking between the separated instrument or silver point, the tube, and Hedström file. The three connected objects can now be removed coronally using relatively high forces. This technique may be more efficient than the endo extractor technique which is using a tube and cyanoacrylate.
