E3 Small Apical Rotary System

Rinse the canal each time after the file is used. Clean the files of any debris repeatedly.

1. Prepare the cavity, locate the orifices and specify the working length of the canal. 
Next, prepare the canal with hand instruments as specified in the Endostar E3 Basic Rotary System clinical instruction.

2. Preparation of the upper part of the root canal.
Shape the canal orifice with the use of the Endostar E3 Basic Rotary System No. 1 (08/30) file until delicate resistance is detectable. Do not apply
excessive force to the instrument especially in highly curved canals.

3. Preparation of the middle part of the root canal.
Begin to work with file No. 2 from the Endostar E3 Basic Rotary System (06/25). Perform up and down movements. Work to a maximum of 1/2 of
working length. Verify the working length with the hand file size 15 and apex locator. Next, with the use of file No. 3 which is part of the E3 Basic Rotary
System (04/30), try to go a few millimeters deeper down the canal. If the file cannot go deeper down the canal, do not force it. Finish the preparation with
the Endostar E3 Basic Rotary System and continue with the Endostar E3 Small Apical Rotary System.

4. Shaping of the apical part of the root canal.
With the use of file No. 1 from the Endostar E3 Small Apical Rotary System (06/20) shape the canal a few millimeters down. Do not force the instrument
down the canal. Take file No. 2 (04/25) and continue to shape the canal. Stop working 2 mm before reaching full working length. Use file No. 3 (04/20) until
the full working length is reached. File No. 3 (04/20) allows shaping even of very narrow and extremely curved canals. Next, go back to file No. 2 (04/25)
and use it until the full working length is reached.

5. Widening the root canal.
After checking the apical width with the NiTi file, consider widening the canal with file No. 3, which is a part of the Endostar E3 Basic Rotary System (04/30)
set. Skip this step in extremely curved canals and finish shaping at size 04/25
