Tooth #18; apical periodontitis.
K3 VTVT sequence. Followed by K3/.04's from small to large.
FAS (final apical sizes): mesials= #40/.04; distals (joined)= #45/.04 - Fred
Gee Fred....I know you didn't squirt it...but you got some pretty good puffs....
you just as well convert to squirting....they look pretty much the same don't you think?

All great cases. BTW this VTVT technique is great!!! Have started using this since a while
and I am more than happy with the shapes. The apex up still gives me a slight flutter though. :-)
No worries about the Apex-Up....light touch, no pushing. - Fred
One question... with which ISO file are you creating a glide path prior to VTVT crowndown?? - Samir.
Size #10 or #15. - Fred
But then Fred.. are we not asking the rotary files' tip to work for us?
If we start with say a 40/04.is the tip not binding in the canal increaing the torque requirements?
Would it help to up the size for the glide path say to a 20 or even 25?? Just wondering...Samir
Based on Johnís recommendation of a month or two ago, I did up my glide path from 15 to 20.
what a difference. Rotaries advance easily (I usually start at a 25 .02), measurements are attained
more easily, I havenít broken an instrument since following his advice. I now use the m4 with a
hand file in it to establish the glide path, and life is much easier. - gary
After glide path to WL (patency) I start with the K3 #25/.10, then the K3 #25/.08.
Now I confirm WL with the EFL. Now enlarge to a size #20 hand file. Then the K3 #35/.06,
the K3 #30/.04, the K3 #25/.06 and finally (if needed) the K3 #20/.04.
After any of the above files reach WL, I usually change to larger .04's.
For deeper shape, you can use again the K3#25/.10 and the K3#25/.08. - Fred
Great as usual. Epiphany or Real Seal I guess? Guy
