Irrigation Needle
Irrigation is a crucial step in root canal treatment. Regardless of the file system being used, up to 35 % of the canal walls remain untouched by instruments1 after preparation. Thus, removal of smear layer and biofilm as well as disinfecting the root canal before filling are key for a successful endodontic treatment.
The Irrigation Needle is designed to complement your endodontic procedure for an efficient cleaning and disinfection until the apex. It can be used after shaping the canal with endodontic file systems like our full treatment solutions: WaveOne® Gold, Reciproc® Blue, TruNatomy® and ProTaper Ultimate™.

How to
Step 1:
Open the packaging by pulling along pre-cut notch provided for this purpose.
Step 2:
Prefill the syringe with one of the compatible irrigation solutions: stabilized sodium hypochlorite up to 6%, EDTA 17%, Chlorhexidine digluconate 2%, Acid citric up to 40%, Dual Rinse® HEDP. Make sure the irrigation solution has been properly stored to avoid the formation of any crystal which could block the vent of the needle.
Step 3:
Insert the “Secure lock” part of the needle into the male nose of the previously filled Luer-Lock syringe and lock the needle by rotating it clockwise.
Step 4:
Make sure the needle is firmly locked on the syringe and expel any residual air from the syringe.
Step 5:
Identify the 4 depth marks on the cannula (18 mm, 19 mm, 20 mm and 22 mm). A stopper may be used to define the working length.
Step 6:
Before entering the canal, check the pressure needed on the syringe barrel to create two equal jets exiting the needle. This step also allows to control the flowability of the irrigation solution.
Step 7:
Start irrigating in the pulp chamber and gently insert the cannula into the canal orifice. Pre-bend the tip to facilitate access into posterior teeth.
Step 8:
Use a scouting file to create a smooth canal pathway.
Step 9:
Determine the working length and re-irrigate with 1 or 2 ml.
Step 10:
Use your shaping sequence. As a rule, after each active instrument used in the sequence, irrigate with 1 or 2 ml of solution, check patency and re-irrigate to eliminate debris. Make sure that the cannula can move freely to ensure constant flowback of the irrigation solution.
Step 11:
As a final rinse, it is recommended to flush the canal with EDTA followed by sodium hypochlorite.
Step 12:
After use, disconnect the cannula and dispose according to local regulations.

Irrigation is a crucial step in root canal treatment. Regardless of the file system being used, up to 35 % of the canal walls remain untouched by instruments1 after preparation. Thus, removal of smear layer and biofilm as well as disinfecting the root canal before filling are key for a successful endodontic treatment. The Irrigation Needle is designed to follow the natural shape of the canal for efficient cleaning until the apex, while minimizing trauma to the surrounding tissues.
Yes, the Irrigation Needle is versatile and compatible with all our DS shaping solutions like WaveOne Gold, Reciproc Blue, TruNatomy and ProTaper Ultimate, enhancing your irrigation process regardless of your preferred solution.
The soft polymer used for the Irrigation Needle allows it to be flexible and follow the root canal anatomy, while the 60° angulation and clearly visible depth indications of 18-, 19-, 20- and 22-mm length are available to facilitate proper positioning of the needle.
The needle features a 27 mm working length, making it suitable for most standard root canal procedures.
Stabilized sodium hypochlorite up to 6%, EDTA 17%, Chlorhexidine digluconate 2%, Acid citric up to 40%, Dual Rinse HEDP.
No, the Irrigation Needle is a single-use device. Do not reuse.
