Here is a case, I hope you will enjoy seeing it as much as
I enjoyed doing it. It's one of the first cases done under
our new microscope. I didn't need it to find the canals here,
but it was very helpful in cleaning the canals - Thomas
congratulations for your beautiful RCT !
And very nice pictures ! - Roberto
Hi Thomas, Very nice case! I have a few questions:
I suppose the tooth needs a crown. Did you consider to
leave a post space?
What was the apical size of the mesial canals?
What do your referring dentists think about having the
build-up made by you? - Marga
Dear Marga, As always great questions.
1. I didn't consider to leave a post space, it's a
"intra-office" referal (like most). Making a post space
when using a "crappy" cold gutta technique is cumbersome.
I have to "change" to warm technique instruments, prepare
the post space and then fill the space with Ca(OH)2
(I never leave it empty). I do it when requested by the
2. I don't remember what the MAF was for the mesials
canals. If I don't forget I will check the patient file
3. In Israel not one dentist will allow me to a build-up
for him for economic reasons. As you may know from my
"whining" e-mails, our ratio of dentists to patients is
about 1:700. Dentists will rather do build-ups then sit
at home. I do ALL the build-ups for my main office in
Haifa. All means all NON cast build-ups. I hate cast
build-ups. I also refuse to do any insurance anterior
build-ups, as they make you put posts into those teeth
otherwise they don't pay - Thomas
P.S I know the rubber dam wasn't that great, but it
didn't want to "hug" the tooth completely. Don't have
any of that nice blue stuff you put in those spaces yet.
Dear Marga, I am in the office now and I checked the
apical size preparation. MB1 - 40, MB2 - 40, DB1 - 45,
DB2 - 45, P - 45.
I hope this is sufficient to eliminate the contamination.
I used Ca(OH)2 for 3 weeks - Thomas
Thanks for your feed-back Thomas, I am convinced that
possible contamination with Ca(OH)2, is not of any
clinical significance - Marga
