Subject:New case of the day
Here is a fun case I did today. The patient presented with moderate
spontaneous pain and tenderness to percussion. The tooth was hypersensitive
to cold. As Jerry said, there is almost always a 4th canal in the maxillary
first molars if you look hard enough. I had to go about 1/3 of the way into
the MB root before the MB2 split off. You could see on the pre-op xray that
it was going to be there. - Rick Schwartz

Rick,
As usual, great case! You are setting the bar quite high, which is
fantastic.
Are you using the Diadent .06 gutta-percha as your master cone prior to
down-pack? Also, about how many times would you say that you needed to
repeat the sequence of .06 series 29 files to finally get the #7 to WL? I
find that on long, narrow roots, the crown-down sequence needs to be
repeated a few times if I want the MAF to be a size 35 or larger. If you
were to use the .04 taper series 29 files files, you will get to WL a little
bit easier. Then you can use the .06 taper #7 as your last file after the
.04 brown goes to length (to get the larger taper). I have played around
with combining .04's and .06's in the more difficult to enlarge cases, and
it "appeared" to be somewhat easier to get there.
I am desperately waiting for the K-3 .06's from Analytic; I tested these in
their prototype phase and they were sharper than the Profiles and appeared
to get to the WL with less recapitulation and greater ease. - Fred

Thanks, Fred. I do use the Diadent .06 gp for the downpack. I usually have
to go through the crown down series 2-3 times to get to the desired size.
Sometimes more. I also do use the .04 tapered instruments on occasion. I
ordered some of the Protaper instruments at the AAE, but they haven't
arrived yet. We are looking forward to trying them. - Rick

Dear Richard and all
1stly: You write that you could see that there was going to be a second MB
canal on the x-ary................my question is --------- how
2ndly: a mention of using water with an ultra sonic instrumentation to
remove bits and pieces out a canal. I missed the post and I would very much
like to get hold of it ------- to read it. If any one has the posting, and
could either forward it to the list or to me personally I would be most obliged
3rdly: to what size do you normally take the MB2 canal? (apical and at what flair?)
Kind regards
John Coetsee
A Fun case
