What is a Hedstrom file?
Hedstrom Files are used for more rapid enlargement of root canals. The cutting edges are inclined backwards, making insertion easy since there is no cutting taking place on the insertion stroke. When the instrument is withdrawn, cutting takes place and debris is carried away from the apex.
What is the difference between Hedstrom and K files?
Both file types prepared straight canals in an appropriate manner but the majority of prepared curved canals were hourglass in shape. In general, K-files created zips which were wider and thus more pronounced than those produced by Hedstrom files. Wide ‘danger zones’ were also regularly created.
What is a rotary file used for?
A nickel titanium rotary file is an engine-driven tapered and pointed endodontic instrument made of nickel titanium alloy with cutting edges used to mechanically shape and prepare the root canals during endodontic therapy or to remove the root canal obturating material while performing retreatment.

What is Gates Glidden drill?
Premier Gates-Glidden Dental Drills are used to open the root canal and to further shape and taper the canal. They are designed so that, should they bind while drilling in the root canal, they will break at the top of the shaft so they can be retrieved easily. Shafts are indented for easy size identification.
What is K file?
K files are the universal standard for canal negotiation, shaping, and recapitulation of root canal systems. They are generally used with a quarter turn “watch-winding” motion and vertical pull. Up to a size 40, the square cross section provides greater rigidity to enhance canal negotiation.
What does K file mean?
Premier K-Files are used to enlarge canal after debridement with a reamer. After reamer, use a file one size smaller than the reamer so that the fragments of dentinal shavings can be carried away from the root-canal walls. Use in clockwise direction (1/4 turn only), then withdraw. Safe-End Tip on sizes 06 – 40.
What are K files made from?
Traditionally, this group of instruments has been made from stainless steel and comprises two basic designs, the K-type instruments (K-files and Kreamers) and the Hedstrom file (Fig. 9.3). The K-type instruments are made from rectangular or triangular blanks.
Should rotary files be used once?
