Passive ultrasonic irrigation (PUI) files of different lengths and diameters, Irrisafe™ files adapt to many sizes of canal:

• Ø 20 length 21mm and 25mm
• Ø 25 length 21mm and 25mm

Irrisafe™ files are used for irrigation once the root canal has been prepared.
20ml of irrigant (NaOCl) are injected into the canal. Irrisafe™ is inserted 2mm short of the working length and activated by performing withdrawal movements to flush the debris and the smear layer upwards. Repeated 3x 1 minute in each canal.
