Unique features and benefits The XO Odontoson instrument tip is equally active on all sides, rotating in a two dimensional movement. This feature enables you to reach all surfaces, without having to change instrument or turn your wrist in unnatural working positions. The instrument tip oscillates with a very high frequency of 42 kHz, giving you high cavitation effect, and effectiveness in removing biofilm and calculus. The amplitude is only 10-20 microns, which minimizes the damage to the enamel, and the discomfort for the patient resulting in a virtually pain free treatment. This feature also enables you to reach very small areas, such as furcations.
