EDDY^® – sonic-powered irrigation tip

VDW presented the sonic-activated EDDY irrigation tip in 2015 as a solution to the limitations of ultrasonic activation and manual irrigation. The EDDY tip, which is made of a soft polyamide, oscillates at an optimum frequency of 5,000–6,000 Hz. This activates the disinfectant solution and produces acoustic streaming and cavitation effects, thereby achieving effective cleansing of the entire canal system.

Study results prove long-term treatment success

Several studies (e.g. Neuhaus et al., Urban et al.) compared the irrigation performance of EDDY with other methods and found that EDDY produces outstanding results: EDDY removed bacterial biofilm in complex root canal anatomies just as effectively as passive ultrasonic irrigation. In addition, the soft and flexible polyamide tip was gentler on the root canal walls. Both sonic-activated and ultrasonic-activated irrigation strengthened the tissue dissolution capacity of the irrigants used equally. Finally, EDDY has been shown to remove calcium hydroxide deposits and debris more effectively and thus proven to be significantly superior to manual irrigation.

Being a single-use tip of universal size, EDDY can be integrated easily and efficiently into everyday practice. The tip is compatible with most standard air scalers, avoiding the need for further investment and thus facilitating changeover.
