Mani K File 25mm #20

Product Description

• This is the dental file with a shank used for enlarging the root canal.
• They are generally used with a quarter turn “watch-winding” motion and vertical pull.
• It is used by the movements of vertical reciprocation or lifting.

• Sharp and mirror-like finishing edge.
• It has high ductility makes for excellent working characteristics.
• Its hard-fiber stainless steel prevents corrosion after repeated cleaning and sterilization.

• Cutting part: Stainless steel (including nickel and chromium)
• Shank: Polybutylene terephthalate (PBT)

• Sterilize the product by autoclave and make sure sterilization is completed before using it. Choose the most appropriate type for each case and follow the general method.

• This product has the possibility that be corrosive if sunk into NaOCl, EDTA and etc. for a long time.

• Apical enlargement: After working length determination the apical part is instrumented first. The first file that binds in the canal at the working length without previous preparation is considered the initial apical file.
• The instruments are bent according to the curvature of the root canal. The root canal must be enlarged by circumferential filing through an additional four sizes.
• If the root canal is strongly curved anticurvature filing method is performed.
• The last file manipulated to the working length should remove white dentin shavings, and is designated the apical master file. With the master file, the apical stop is defined.
• Only the K files used in the step-back technique provided a definitive apical stop, an almost round canal cross-section, a very good apical preparation without any indentations, as well as a conical canal shape from apical toward coronal.
