Endostar E3 Azure Small

An innovative system created with Azure HT Technology

Endostar E3 Azure is an innovative system created with Azure HT Technology which is our specially designed heat-treatment manufacturing process. The goal of Azure HT Technology was to create files that are extremely flexible and resistant to breaking even in the most complicated clinical cases. Endostar E3 Azure Small is not a separate rotary system. This is an extension of the Endostar E3 Azure Basic for use with very narrow and curved canals. The canal should be first shaped with the use of Endostar E3 Azure Basic files or Endostar E3 Basic.

  • Safe - increased breaking resistance
  • Extremely flexible - follows even the most curved canal path
  • Effective and easy to use


Color of power



The Azure HT Technology process modifies the crystal structure of the nickel-titanium files. It allows for the martensite to austenite transformation to occur at near body temperature.

This process completely changes the properties of the files. The files can pre-bent before being inserted into the canal. They can easily follow even the most curved canal path, with a minimal risk of perforation, ledges or via falsa.

Feel the significant difference. New and unique.

During root canal treatment (at near body temperature) the file uses the advantages, both of the martensite and austenite phases.


  • more flexibility
  • can be pre-bent
  • greater resistance to breaking


  • super elasticity
  • high and effective cutting ability
  • resistant to twisting forces


Increased flexibility thanks to Azure HT Technology*
*Internal tests according to ISO product standards.


Increased resistance to twisting forces compared to standard rotary instruments.

Do it your way

We aimed at designing a new user-friendly system, which would be flexible, efficient and safe. We had no intention to change doctor’s habits. Endostar E3 Azure was designed for 3 common types of the motion to achieve a perfect root canal preparation. The system is compatible with most of the handpieces.


Rotary motion

The instruments rotate clockwise and with a set speed (CW - clock wise).


Reciprocal motion

The instruments perform alternating clockwise (CW) and counter Clockwise (CCW) movements; the angle of clockwise (CW) rotation must be larger than counterclockwise rotation (CCW) e.g. 90 degrees CW and 30 degrees CCW.


Complex motion

Combines the rotary and reciprocal motion. The files rotate until too high resistance in the canal is met. Then the reciprocal mode is activated (CW - CCW, net CW). Rotation mode is turned on again when the resistance returns to acceptable level. An example of complex motion is the OTR mode available in the Endostar Provider endomotor

Endostar E3 Azure Small instruction of use:

  1. Rinse the canal each time after the file is used. Clean the files of any debris repeatedly.
  2. 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.
  3. 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.
  4. Begin to work with file No. 2 from the Endostar E3 Azure Basic  (06/25). Perform up and down movements. Work to maximum of 1/2 of working length. Inspect the working length with the size 15 hand file and apex locator. Next, with the use of file No. 3 which is part of the E3+ 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.
  5. 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 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 full working length is reached.
  6. After checking the apical width with the NiTi 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.

CE mark

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.

Files in the package may vary slightly in color, and the blades may be slightly arched. These differences do not affect the quality of the product. They are result from the applied heat treatment.

Files should be used with motor speed at 300 rpm.

The torque settings indicated in the table above table are for example only and may vary according to each user preferences and motor capabilities. Do not exceed the upper torque limit which is different for each instrument. If precise torque settings cannot be set, and only manufacturer-specific torque levels are available, be sure to select one that does not exceed the recommended limit.
