Lower Bi : CaOH2

Necrotic case, two visits, CaOH2 in between. When I first saw the
preop-xray I thought, that this would be a easy one. I then had a
second look ( thank you Winfried!) and recognized that the canal
seems to disappear after 10-11 mm. So I planned the next appointments
for two canals. But after getting access I did not see a lingual canal.
So I cleaned and shaped the buccal and was very disappointed not to
find another one. I started troughing on the lingual canal wall but
did not find a orifice even with prebended handfiles and microopener.
Afraid of "creating" a artificial canalsystem I decided to fill the
buccal one. After drying I saw a very little wet point on the lingual
wall (just a reflex of the scopelight) Took a ISO 10 microopener and
there it was. Buccal 10/45 with handfiles an stepback after VTVT with
Flexmaster. Lingual FM 06/35. No off angeled x-ray because I could not
place the Kodak XL sensor deep enough. So I was happy to get the apex
on the film. The thing I learned today: Always have a last look.

very cool. it's crazy learning to "see" with the scope. it isn't just
as simple as "looking", we have got to learn to read some subte clues
It helps when we Know the canal must be there, as you can see from
your pre-op eval.
Awesome work as always.
For this tooth the easiest angled shot would be to swing the tube head
to the mesial, shoot toward the distal. i have one assistant i work
with that is fairly good at these, but i find it's better to just shoot
them myself (the radiograph, not the assistant) - Kendel
Kendel, I always shoot them myself. Had a lot of new assistants last
year as endo became a bigger part of my dental life ;))). As long as
here in germany a lot of patients (and sometimes collegues) are very
concerned about taking two radigraphs from the same tooth the same day
(i.e. off-angled films ) I will "shoot" them myself , trying to avoid
Excellent work, superb documentation, I really like this one - Thomas
