K3 VTVT sequence.  On the first pass, the #20/.04 reached WL on the mesials, and a #30/.04 on the distal.
The mesials were then instrumented using the VTVT in reverse--#25/.06 did not reach WL, but the #30/.04 did.
I then used a #35/.04 and a #40/.04 to WL.  For the distal canal, I went up to a #50/.04 to WL.

I have been trying this for some time now, and it seems to go quite efficiently - Fred



fred, nice case.
if you look carefully at the fill in both mesial and distal fills, there are voids.
the problem with resilon's radioopacity seems to me , there is a potential for  voids to be masked .
same fill with guttapercha may show the voids more.
having said that , this resilon is definitely more flowing than GP and the fills may be more homogeneous
in my opinion  what do yu think? - Sashi  Nallapati

Sashi, do you think that these voids are or any consequence that high up...especially when you bond the
floor of the access prep?  Very often they are still surrounded by bonded Epiphany as sealer or cone.  Guy

Nice case Fred......I too am doing the same with my cases and find it
works well.  I still do use the VTVT and K3 as I like what it does for me.

Usually get up to a 20 handfile by going apically past the foramen with
smaller files and occasionally if I cant get the 20 down but the 15 will
go I will open up the coronal 1/3 with orifice shapers and then the 20
always goes to length.

Neat stuff Fred - Glenn

Did you use a hand file on the apex of the distal root?  Guy
