The Endo 3 Ultrasonic Endo Activator is an highly convenient intelligent ergonomic design, wireless handpiece for activating irrigation during a root canal procedure. This unit replaces the Endo 1 and has some upgraded features. Proper irrigant activation in the canals during a root canal plays a key role in the proper debridement and disinfection of the root canal system. The Endo 3 emits a high-frequency ultrasonic vibration to safely and effectively boost the endo irrigation used in endodontics.
