23 © 2006 J.Bringas, DMD, DDS, MS Coronal Preparation Use the ProFile GT.35/.12, 17mm file. The color band denotes size. Green band means a size 35.

24 © 2006 J.Bringas, DMD, DDS, MS Coronal Preparation Use the ProFile GT.35/.12, 17mm file. The color band denotes size. Green band means a size 35. Each band denotes 0.02mm of taper, thus 6 x (0.02) = 0.12mm taper.

25 © 2006 J.Bringas, DMD, DDS, MS Use of Rotary Handpiece Use 8:1 gear reduction attachment. Run at constant speed: – (500 rpms) –20 series & 30 series (300 rpms) USE LIGHT PRESSURE.

26 © 2006 J.Bringas, DMD, DDS, MS Use of Rotary Handpiece Start the handpiece before entry into the canal and maintain at a constant rpms. The file should not be in contact with canal walls for more than 5 seconds. Advance the file slowly and carefully in mm increments using constant light pressure. NEVER FORCE A FILE IN A CANAL.

84 © 2006 J.Bringas, DMD, DDS, MS FAQ #1 I reached MAR with a 20/.06 file, do I still use a 20/.04? Answer: This is usually common with larger canals. There is no need to use the 20/.04 file, it is ok to move to the 30 series.

85 © 2006 J.Bringas, DMD, DDS, MS FAQ #2 I am done using the 20/.04 file but I have not reached MAR length yet… what do I do? Answer: This is true for narrower canals. If this scenario happens, cycle through the files again until you reach MAR.
