Coronal Preparation
• Use the ProFile GT .35/.12, 17mm file.
•The color band denotes size.
•Green band means a size 35.
© 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.
© 2006 J.Bringas, DMD, DDS, MS
Use of Rotary Handpiece
• Use 8:1 gear reduction attachment.
• Run at constant speed:
– 35 0.12 (500 rpm’s)
– 20 series & 30 series (300 rpm’s)
• USE LIGHT PRESSURE.
© 2006 J.Bringas, DMD, DDS, MS
Use of Rotary Handpiece
• Start the handpiece before entry into the
canal and maintain at a constant rpm’s.
• The file should not be in contact with
canal walls for more than 5 seconds.
• Advance the file slowly and carefully in
0.5 -1.0 mm increments using constant
light pressure.
• NEVER FORCE A FILE IN A CANAL.

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.
© 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.
