ABSTRACT:
Disclosed is a dental file for use in cleaning out or extirpating root canals, particularly those which are curved, wherein the file which conventionally is provided with cutting or abrading flutes, typically in a spiraled manner, is also provided with a smooth, non-abrading pilot end which rides on the deep inner portion of the root canal wall and prevents the file from straightening out and causing the end thereof to "zip" or slice into the canal wall in an uncontrolled manner.
