Thoroughly irrigating the entire root canal system – including isthmi and lateral canals – is an important step within the endodontic treatment process. It’s as crucial for the long-term success as challenging: the sensitive dentin structure needs careful handling, and the deeper areas of the roots are difficult to reach.
Made from a flexible polymer material, EDDY can easily go round curves, maintaining the integrity of the root canal anatomy. With vibration of 5,400 to 6,600 Hz, it creates a three-dimensional movement for an effective oscillation that triggers two cleaning effects: cavitation and acoustic streaming.
One size fits all. Due to its high flexibility, EDDY fits almost every canal anatomy.
Please find all compatible airscalers and coupling components here.
Care must be taken to ensure that EDDY is inserted into the root canal only up to 1 mm short of the apex to reduce the risk of damaging the apex area / bleeding and of extrusion of irrigant beyond the apex.
Only use irrigation solutions commonly used in endodontics to irrigate the root canal, e.g. EDTA 17 % or NaOCl solution [5.25% max].
The frequency of the air scaler should be comprised between 5,400 and 6,600 Hz [Air supply according to air scaler IFU].

“If you compare the activation of irrigants with EDDY to other activation techniques, it is evident that EDDY triggers a cyclone.”
Dr. Mauro Amato, Switzerland
“After just a few seconds of using EDDY there is no debris visible on the entire root canal wall and NaOCI seems to work better.”
Dr. Vittorio Franco, England and Italy
