What is a Hedstrom file?

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 When the instrument is withdrawn, cutting takes place and debris is carried away from the apex.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 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?
