Endodontic treatment (Step Back Technique)

is also known as Telescopic canal preparation or serial root canal preparation.

Step back technique emphasizes keeping the apical preparation small

This technique was first described in 1960 by Mullaney

phase I involves the preparation of apical constriction

and phase II involves the preparation of the remaining canal

Evaluate the carious tooth before initiating endodontic treatment

prepare the access cavity, and locate the canal orifices

Establish the working length of the tooth using pathfinder

The working length is the distance between the reference point coronally and the anatomical apex

first by x ray that taken while the file is inserted in the canal

In this situation Apical foramen is usually found 0.5-1mm

That  designed to determine the canal length by

giving the reading when the file tip is at the apical foramen

first lubricate the instrument for use in apical area

Now insert the first K file into the canal

with considering the working length with gentle

of file with minimal apical pressure is given

Remove the instrument and irrigate the canal

to the working length in similar manner and again irrigate the canal

Don't forget to recapitulate the canal with

or 30 H-file that reaches the working length

Place next file in the series to a length 1 mm short of working length

Repeat the same procedure with successively larger files

at 1 mm more shorter from the previously used file

push-pull strokes to achieve a smooth taper form of the root canal
