Subject: [roots] #18 3-rooted
Fun tooth, the first 3 rooted lower molar I get to do.
Previously accessed by GPR, but the pt came back before their scheduled
appointment due to persisting pain. Temporary restoration consisted of
cotton and IRM.
Scan taken initially and then at completion. The M root is quite wide
as seen on the scan and I was expecting 2 canals, but troughed out the
isthmus and nothing. I walked away from this case with a strange feeling that
I had missed a canal in that root.
Looking at the scan post-op, the obturation seems centered and uniform.
Comments from previous experience on these? - Melissa
Hi Fred.....Pretty great student you got there Fred......takes after the
guy in charge I guess!!. Nicely handled case. Do you get any patients
questioning the dosage of the CbCT after the articles last week.
Thanks Glenn. So far no questions about the radiation dose. We have a
laminated chart hanging in the radiology room. - Fred
Thanks Fred........just out of interest what does the laminated card say?
What do you think of Parkell's Metaseal as a resin sealer? - RP Fitton
I don't know much about it, but I think it sets quite hard. If that is the
case, retreatment will be a bear - Fred
Hi Melissa, Very wel done and nice documentation. Is it possible to answer
the following questions:
1/ wat kind of preparation technique did you use
2/ the same for obturation
3 wat is that white materiaal you put around the tooth .I use blockout but
this one looks beter - Paul NOYER
The prep was handfiles and rotary instrumentation; using K3's and Sequence
files. Obturation was warm vertical using Resilon. Opal Dam is used to seal
the rubber dam - Fred
Note the difference between medical ct and dental cbct. 18x the exposure
with ct, cbct is nominally above routine dental radiation. And with the
smaller field Kodak, probably equivalent - gary
