E3 Basic Apical Rotary System
Endostar E3 Rotary System is a set of modern rotary files used for effective and efficient root canal preparation. They are manufactured from the highest
quality nickel-titanium alloy, which provides durability and flexibility. The files can easily fit even strongly curved canals, this way minimizing the risk
of canal perforation. The modified shape of the NiTi S file with two 90-degree cutting edges ensures efficient cutting, transport of debris up the canal and
decreases preparation time. The inactive tip allows safe preparation, minimizing the risk of a via falsa, perforations and zipping. Easy-to-read taper
value (number of stripes on the handle) and ISO size (color stripes) enables effortless use of the instruments. The Endostar E3 Basic Rotary System should
be used with a normal width, straight or slightly curved canals.
Clinical instruction for use
Rinse the canal each time after the file is used. Clean the files of any debris repeatedly.
1. Cavity preparation.
Prepare the cavity. Use a rubber dam.
2. Location of canals.
Locate all canal orifices. Lubricate the canals.
3. Specifying the working length of the canal.
Specify the working length of the canal using your method of choice.
4. Preparing the canal with hand instruments.
Continue to shape the root canal with hand files up to size 20. This way, you will create a glide path (Endostar EP Easy Path recommended) for
rotary instruments. This will also reduce the risk of breaking the rotary file.
5. Preparation of the upper part of the root canal.
Shape the canal orifice with the Endostar E3 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 Small Apical Rotary System).
6. Preparation of the middle part of the root canal.
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. Shaping of the apical part of the root canal.
Use file No. 3 (04/30) to widen the apical portion of the canal until the 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 nickeltitanium 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 Big Apical Rotary System.
