Endo Equipment Parts & Accessories

About endo equipment parts and accessories

These are the tips, spares and attachments that endodontic equipment takes, among them the activators used to agitate irrigant inside the canal. Ultrasonic activation runs at frequencies between 25 kHz and 40 kHz and creates acoustic streaming in the irrigant, and under the right conditions cavitation. Passive ultrasonic irrigation puts a non-cutting ultrasonic file into a canal filled with irrigant; the vibration raises fluid velocity and helps detach microbial aggregates from the canal walls.

Fits an endodontic unit; it is not the unit itself. Sonic activation uses much lower frequencies, roughly 150 to 300 Hz, with polymer tips that oscillate to stir the irrigant.
