sonic activated irrigation Proven: EDDY rinses every canal safely and effectively More than two years’ experience in everyday practice and study results have proven that the EDDY sonic-activated irrigation tip by VDW cleans even severely curved root canals safely and effectively. VDW presented the sonic-activated EDDY irrigation tip in 2015 as a solution to the limitations of ultrasonic activation and manual irrigation. The 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. The polyamide tip, softer than dentine and particularly gentle, enables effi cient chemical disinfection of side canals, apical ramifi ca- tions and isthmi owing to oscillating 3-D movements. The fl exible tip adapts itself to every canal anatomy without the risk of creating ledges or perfora- tion. Another advantage is that, during the preparation, EDDY requires only a maximum of 30 seconds per rinse interval—a considerable saving of time and increased effi ciency compared with manual irrigation with cannulas. 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 biofi lm in complex root canal anatomies just as effectively as passive ultrasonic irrigation did. In addition, the soft and fl exible polyamide tip was gentler on the root canal wall. Both sonic-activated and ultrasonic-activated irrigation strengthened the tissue dissolution capacity of the irrigants used equally. Finally, EDDY removed calcium hydroxide deposits and debris more effectively and thus prove to be signifi cantly superior to manual irrigation. Being a single-use tip of universal size, EDDY can be integrated easily and effi ciently into everyday practice. The tip is compatible with most standard air scalers, avoiding the need for further investment and thus facilitating changeover. A list of references can be obtained from the company.

The outstand- ing feature of this new instrument is its ability to be used both on its own and in combination with the new apex locator from FKG, the S-Apex. Rooter S also has completely functions which guarantee greater safety for the user.

This is assisted optimum visibility in all quadrants. This is assisted above all in the molar sector by the extremely small head, which has an integrated electrode fi le. With speeds from 50 to 1,000 rpm, users have the choice of eleven different speed set- tings to suit their individual needs. The user can adjust all functions by push-button and can adjust all functions by push-button and store the settings at six storage locations. The easy-to-read colour display shows all the relevant information and settings and can the relevant information and settings and can be turned through 180° for left-handed us- be turned through 180° for left-handed us- ers. Acoustic signals further assist root canal preparation as the user does not have to keep looking at the instrument’s display. The Rooter S and S-Apex combination Rooter S combines with S-Apex offers an additional safety function: “Auto Apical Slow Down” reduces the rotational speed automatically as soon as the fi le tip approaches the reference point. This means that the instrument can guarantee the highest possible safety for both user and patient because it prevents the critical point in the apical area user and patient because it prevents the critical point in the apical area from being exceeded. S-Apex carries out an exact length measurement during treatment so S-Apex carries out an exact length measurement during treatment so that the user can prepare the root canal safely. This is particularly that the user can prepare the root canal safely. This is particularly important in order to prevent any later complications. The Rooter S can also be connected to the apex locator by data transfer cable in order to provide additional functions such as “Auto Start and Stop” or automatic stop as soon as the fi le has reached the reference point (“Auto Apical Stop”). www.fkg.ch www.fkg.ch roots 4 2017 43
