=== Dental files ===

During [[root canal therapy]], round files ranging from {{convert|.06|to|0.8|mm|adj=on}} diameter files are used to smooth the narrow canals of the interior of the tooth and thus facilitate disinfection of the internal surface. Typically the files are made of [[stainless steel]] or [[nickel titanium]] (NiTi) and come in a variety of styles. Mechanized files, known as rotary files, are also commonly used. These files attach to the head of a specific oscillating or rotating drill.
