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.
- GLenn

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? - Glenn

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
