K-files

Canal irrigation

Files of different lengths and diameters, taper 2%. The K files adapt to many sizes of canal:
Ø 10 length 21mm and 25mm
Ø 15 length 21mm and 25mm
Ø 25 length 21mm and 25mm
Ø 30 length 21mm and 25mm
The indications for K files are irrigation, withdrawal of calcified dentine and gutta percha, and the withdrawal of broken instruments.
For irrigation ultrasonic files are used with a disinfectant solution. To provide a final decontamination, use sodium hypochlorite until the smear layer is removed.
K files are very sharp instruments and should be handled with precision. However they are flexible and can therefore be pre-bent.
