E3 Azure Small

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
Azure Basic clinical instruction for use.

2. Preparation of the upper part of the root canal.
Shape the canal orifice with the use of the Endostar E3 Azure Basic 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 portion of the root canal.
Begin to work with file No. 2 from the Endostar E3 Azure Basic (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 Azure Basic
(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 Azure Basic and continue with the Endostar E3 Azure Small.

4. Shaping of the apical part of the root canal.
With the use of file No. 1 from the Endostar E3 Azure Small (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 hand file, consider widening
the canal with file No. 3, which is part of the Endostar E3Azure Basic
(04/30) set. Skip this step in extremely curved canals and finish shaping
at size 04/25.
