ABSTRACT:
A tool for use in bending root canal files is disclosed which grips a file between an upper jaw with a plastic insert to protect the surface of the file and a lower jaw having a file bending anvil thereon. The file bending anvil has ten specific bending diameters thereon, and the file is bent by gripping it in the jaws and wrapping it around the desired specific bending curve. A template having circles thereon corresponding to the specific bending diameters on the file bending anvil may be used with an X-ray of the root canal to select the appropriate bending diameter for the file.
