Kinda like these cases you posted Barry?
There are other problems with these cases as well.... John A Khademy
Punked or Peesoed ;-)) - Fred
Barry, What's are these? (Dotted yellow line looks like PDL to me)
Black gap by blue arrow that continues down the root...
Radiodense mass by green arrow.....
Mesial canals....Hmmm.....are those really a size 35? - John
John, You got me. Perhaps, the dentin is thinned out more than
it should be. The cases are certainly working and I'm going to
guess that most on Roots would say they are well done. However,
your point is appreciated which is why we developed the new
tapered peeso called the pleeser which significantly reduces
the potential to take away excessive tooth structure. The
concept of straight line access however is a good one and
allows greater freedom in shaping the apical end of the canal
to a diameter that truly removes the pulpal contents along the
entire length of the canal. I have seen so many beautiful white
lines in molars done with rotary Niti where the prepartion is
obvioulsy no more than a 25/04. Pretty picture, but it doesn't
necessarily do the job that is required of them particularly
in the bucco-lingual dimension. When concern for separation
determines the degree of apical preparation there is a
fundamental problem with those techniques and those advocating
them the way they are presently being used. In the meantime,
you are the best at finding those extra canals - Barry
What are "Extra canals" ? They are either canals or not
surely - Bill
Def. Extra Canal:
1. a major root canal system that requires additional productive
chair time to treat, that if missed would not be
noticed by an amateur clinician viewing a poorly taken radiograph.
2. Any portion of a root canal system that fails to concern the
business interests of an entrepreneurial endodontist.
3. Root entitities that fail to be covered by insurance codes if treated.
4. Synonymous with, and Anonymous as extra-terrestrial in
New York City. - Terry
Terry, you made me a smile and weep at the same time. Weep for
the truth in that statement (too much true here in Israel) and
smile for the sarcasm - Thomas
When I hear that Universities are teaching that microscopes don't
make a difference, and that finding all the canals isn't important
I really wonder what we have come to. In a way I'm glad that not
everyone finds all the canals, it at least provides me with some
work - Bill
Bill, here in the u.s. the univ of Maryland just put in 16 scopes,
and 7 or 8 of them are NOT dedicated to endo. Two of the guys with
me this past weekend were instructors at the university of Virginia,
they are putting one in for the residents, and are going to have
their residents rotate over to wayne’s office for instruction.Progress
is being made, albeit S-L-O-W! - Bill
