Endostar E3 Azure Basic – instruction of use

1. Prepare the cavity. Use a rubber dam.
2. Locate all canal orifices. Lubricate the canals.
3. Specify the working length of the canal using your method of choice.
4. Continue to shape the root canal with hand files up to size 20. This way, you will create a glide path for rotary instruments instruments. This will also reduce the risk of breaking the rotary file.
5. Shape the canal orifice with the Endostar E3 Azure Basic File No. 1 (08/30) until you reach a maximum of 1/2 of the total canal depth. Do not use this file when the canal is highly curved (in such cases use the Endostar E3 Azure Small ).
6. Begin to work with file No. 2 (06/25). Perform up-and-down movements. Shape the canal up to 2/3 of the working length. Inspect the working length with the size 15 hand file and apex locator. Next, insert file No. 2 at full working length.
7. Use file No. 3 (04/30) to widen the apical portion of the canal until full working length is reached. Confirm that full working length was reached with hand file size 15 and apex locator. Next, finish work with a nickel-titanium hand file size 30. Check if the file can be inserted at full working length without obstructions, and if wedging can be felt. If a wider preparation of the apex is needed, continue to work with larger hand instruments size 35, 40 etc. or consider using the Endostar E3 Azure Big.

Endostar E3 Azure instruments can be repeatedly sterilized and used, provided that the visual inspection performed by the dentist prior to use shows that the instrument remains undamaged, is not bent, deformed, does not show signs of blade wear and can be securely attached to the handpiece. Particular attention should be paid to the winding (or excessive twisting) of the windings of the file.

The instrument windings should be regularly spread over the entire length of the blade, if in one point of the blade the windings are too close or too far apart (there is no regularity in the windings growth of the unused instrument), this is a sign that the instrument could break in the canal.

Permanent deformations of the instrument, especially bends, which do not have the form of an arc and have a visible break point should be always controlled before re-use.  The heat-treated NiTi alloy allows these instruments to bend in the form of an arc.

In case of doubt, the file can be placed in any environment (fluid, air) at a temperature slightly above 40⁰C for a few seconds, then the blade should be straightened or curved on a very smooth arc. If the file is still deformed, it means it is permanently deformed and could not be use again. After each use, check that the blade is securely placed in the file grip. If the file has been subjected to high torsion force, especially in highly curved canals the instrument should be used only once.

Dispose of file which appears to be defective.
