A NEW METHOD FOR RETRIEVING SILVER POINTS AND SEPARATED INSTRUMENTS FROM ROOT CANALS

A new method for the removal of metallic canal obstructions is present ed. After gaining access to the coronal end of the separated instrumen t or silver point, a circular groove is prepared around it using ultra sonic tips. A short piece of fine stainless-steel tubing can now be pu shed over the exposed end of the object. A Hedstrom 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 s eparated instrument or silver point, the tube, and Hedstrom file. The three connected objects can now be removed coronally using relatively high forces, This technique may be more efficient than the endo extrac tor technique which is using a tube and cyanoacrylate.
