Endodontic file sizes & coloursĮndodontic files have a universal handle colour scheme and are available in three different lengths of 21mm, 25mm and 31mm. The taper of an endodontic file can be used to work out the diameter of the file at any working point.įor example, to work out the diameter of the final cutting flute of a particular file, which is always 16mm down from tip, the following equation for a.

Stainless steel endo files, such as K-files and H-files, have a pre-set taper of. Tapers are the cutting points along the file. Endodontic file taper explainedĪn endodontic file’s taper indicates how much thicker in diameter the file gets for each 1mm you go down from the tip of the file.

Over recent years, NiTi files have become the preferred choice of file for many dentists due to the superior flexibility provided. NiTi files can be used within rotary systems or manually for fine control. NiTi is the most popular alloy used today in endodontics. Hedstrom files have a spiral cone shape and only cut in retraction when the file is pulled outwards. K-files have a twisted square shape and are used in a reciprocating clockwise-counterclockwise motion. They are generally used prior to rotary files. They are typically used to locate canals and create a glide path. K-files and H-files are stainless-steel hand files. The three most widely used types of endodontic files are NiTi (nickel-titanium) files, K-files (Kerr) and H-files (Hedstrom). The three main uses of an endodontic file are to remove diseased pulp tissue in the canal, shave dentine from the canal space and to shape the canal so that it can be filled properly.Ĭoming in a variety of different materials, designs and sizes, our guide aims to make it easier for you to identify the best endodontic systems for your root canal treatments.
