Golden rules

• Let the instrument work.
• Work 3-4 seconds in a row, get out, clean the blade and irrigate the canal.

D-Race 1 blister includes / contient / enthält : 2 x DR1 + DR2
« Desobturation » prior to retreatment, because access must be made, the entrance of the canal « desobturated » to reach inside the canal itself so that it could be properly retreated. Retreatment must be achieved because the first RCT failed or needs improvement.
D-Race will desobturate most canals, whatever the filling used – gutta-percha, carriers, paste, resin-based materials. D-Race removes a large part of the ancient filling material. With only 2 instruments time is saved and safety of treatment is increased.
Once desobturated, the canal will be retreated.

**General advice to take into consideration for removal of filling

material**

1. Take 2 x-rays from different angles.
2. A precise appreciation of canal anatomy is very important.
3. Find entrance of canal and access the obturation material.
4. Prepare, if needed, a cavity 1-2 mm with DR1 and drop solvent to soften obturation material. If necessary, use a heat plugger or ultrasonics.

Coronal third preparation

1. Gently engage DR1 rotating at 1000 rpm (recom. torque 1.5 Ncm) into the obturation material.
   The active tip of DR1 facilitates the initial penetration.

Median and Apical thirds preparation

1. Insert DR2 rotating at 600 rpm (1 Ncm).
2. Don’t force the way, clean and check the blade regularly.
3. Continue to advance apically as long as filling material is visible on the flute.
4. If needed, drop solvent to help removal of obturation material.
5. Establish final WL and finalise shaping with standard NiTi Race files.
