EDDY® tips are powered at a high frequency of up to 6,000 Hz by airscaler. The vibration produced is transferred to the polyamide tip, which – thanks to the special qualities of the material – is moved in an oscillating motion at high amplitude. This three-dimensional movement triggers cavitation and acoustic streaming attributed with higher cleaning efficiency.

Sonic powered EDDY tips bring the same effectiveness to activating irrigants as ultrasonics, but due to the soft polymer tips, sets a new standard of combined safety and efficiency. Furthermore, EDDY demonstrates its versatility by supporting placement and removal of calcium hydroxide as well as placement of sealer.

Product information

Three benefits in one solution

EDDY is made from a safe and flexible polymer material, unlike the stiff metal of irrigation needles and ultrasonic tips. Thus, it can easily go around curves – maintaining the integrity of the root canal anatomy.

  • Reliable removal of residual tissue and dentine chips
  • Closer approximation to the apex than a metal tip
  • Forgiving material with low risk of fracturing the tip or damaging the dentine

With vibration of 5,000 to 6,000 Hz, EDDY creates a three-dimensional movement. The polymer material of EDDY causes a highly effective oscillation in the irrigant that triggers two cleaning effects: cavitation and acoustic streaming.

  • Three-dimensional movement for irrigant activation
  • Extended reach through oscillation
  • Physical effects intensify cleaning performance

Research* not only shows that sonic action helps to remove debris and reach areas difficult to clean through mechanical preparation. It is also proven that EDDY tips activated by an airscaler at 6,000 Hz perform equal to or better than passive ultrasonic irrigation.

Expert opinions


Dr Winfried Zeppenfeld

EDDY irrigates the canal clean and is aggressive on biofilm but gentle on the tooth with no danger of ledges or perforations.


Dr Mauro Amato

If you compare the activation of irrigants with EDDY to other activation techniques, it is evident that EDDY triggers a cyclone.

England & Italy

Dr Vittorio Franco

After just a few seconds of using EDDY there is no debris visible on the entire root canal wall and NaOCl seems to work better.

Which air scalers can be used with EDDY?
Why doesn´t EDDY fit on KaVo SONICflex 2008 but on the prior model KaVo SONICflex 2003?

There are 2 different thread types for KaVo air scalers on the market. KaVo SONICflex 2000 & 2003; These are compatible with EDDY [M3 thread]. KaVo SONICflex quick 2008 has a quick coupling with only one thread gear which is not suitable for EDDY´s plastic thread.

Which coupling is necessary to use the W&H air scaler in the EDDY Starter Kit?

The W&H air scaler models in the Starter Kit is compatible with all KaVo MultiFlex respectively Sirona- couplings. In all other cases, the air scaler model has to match the type of coupling of the dental unit.

Basically, how do I proceed with irrigation with EDDY?

Protection of clothing and eyes! Screw EDDY clockwise into the thread of the air scaler hand piece manually. Introduce EDDY into the prepared root canal and fill the pulp chamber with a suitable irrigation solution e.g. NaOCI solution. Activate the air scaler and move EDDY carefully up and down with vertical motions. Do not exert any additional manual pressure. Repeat irrigation with EDDY after every preparation step.

Additional product information

Perfect integration into your workflow

EDDY can easily be integrated into daily practice, as no documentation for the number of usages is needed. The tip is also compatible with a variety of airscalers.

  • Sterile packaged single-use tips
  • Cost-efficient and time-saving
  • Easy implementation with one tip regardless of canal size
