Mani K – File 28 mm # 06

Features

Description

Mani K- Files 28mm is an extraordinarily sharp and mirror-like finished edge with high ductility makes for excellent working characteristics.
The hard-fiber stainless steel prevents corrosion after repeated cleaning and sterilization.

INDICATION –

This is the dental file with a shank used for enlarging the root canal.
They are generally used with a quarter turn atch-windingmotion and vertical pull
It is used by the movements of vertical reciprocation or lifting.

ADVANTAGES –

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.

Direction to Use

The K-file works on the “pull” stroke – that is, by scraping the canal walls as it is withdrawn from the canal.
It is advanced to the full working length rotated 1/4 to 1/2 turn clockwise, and withdrawn while being pressed against one of the walls.

Steps of the Step-back technique.

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.
The minimum size of AMF is 25# in case of irreversible pulpitis and 35# if the root canal is infected.

Irrigation: Copious irrigation is important throughout the shaping of the canal walls, as the filing and reaming actions used during cleaning and shaping generate debris, which also can lead to infection and inflammation of the root canal or apical region. Copious irrigation helps to clear the loosened debris out of the canal and also serves to facilitate
instrumentation by lubricating the canal walls and by removing materials that can create a blockage in the canal.

Step back phase: Recall the working length of the canal and the size of the last file (AMF) used. Subtract 1mm increments from the original working length with each larger file
size used until the instrument reaches within 4-5 mm of the canal orifice.
