Only DENTSPLY Professional’s Cavitron® systems deliver new Tap™-On Technology. Tap™-On Technology improves efficiency and is designed to reduce hygienist leg strain. A single tap activates or deactivates scaling or air polishing, allowing you to rest your foot during the procedure. New prophy mode auto cycles alternate between air polish and rinse without a need to touch the pedal. Plus additional power options and more precise water control.
