【Features】

·Safe working tip has no cutting function and only has a guiding function to avoid dangers such as steps and slopes in the root canal.

·Thread processing has sharp edges, which is more conducive to cutting and has good chip removal performance.

·Fine polishing patented technology, more complete surface treatment

【Steps】

1. First use a 10# stainless steel K file to initially explore and dredge to the middle and lower section of the root canal. The hand file must be pre-bent.

2.19/07 The open file removes the dentin overhang in the middle and upper section of the root canal to establish a good straight entrance.

3. Use a 10# stainless steel K file to measure the working length, and prepare a 15# stainless steel K file to the root tip.

4. Use a 15/03 channel file to establish smooth access to working length.

5. Use a 10# stainless steel K file to back file to clean the debris and use sodium hypochlorite solution to flush the root canal.

6. Use 20/04, 25/04, 25/06, and 35/04 in sequence to prepare the root canal to the working length, and use a 10# stainless steel K file to backfile and rinse the root canal.

7. Use a 10# stainless steel K file to check whether the apical area is properly prepared. You can measure the working length again to ensure the accuracy of the root filling.

8. Ultrasonic cleaning of root canals.
