Recommended number of use:

Maximum of 5 times, provided that visual inspection performed by the practitioner prior to use shows that the instrument remains undamaged, is not bent, deformed, does not show signs of blade wear, and can be securely attached to the handpiece. If the file has been subjected to high torsion force, especially in highly curved canals, the instrument should be used only once.

Files should be used with motor speed between 150 and 300 rpm.

The torque settings indicated in the table above table are for example only and may vary according to each user preferences and motor capabilities. Do not exceed the upper torque limit which is different for each instrument. If precise torque settings cannot be set, and only manufacturer-specific torque levels are available, be sure to select one that does not exceed the recommended limit.

Clinical instruction for use

Rinse the canal each time after the file is used. Clean the files of any debris repeatedly.

1. 1. Prepare the cavity. Use a rubber dam.
   2. Locate all canal orifices. Fill the canal orifice with a lubricant.
   3. Specify the working length of the canal with your method of choice.
   4. Make sure all canals are patent up to a depth of 2-3mm from the apex with the help of the K15 file. For very curved and narrow canals, use a different hand instrument, size 06, 08, or 10.
   5. Create access to the canal orifice using rotary files with a greater taper (06, 08) or with the use of Gates-Glidden drills.
   6. Start working with the 02/15 or 02/20 file until you reach the full working length and then switch to other instruments (02/25, 02/30, etc) until you reach the desired canal size.
