Subject: [roots] Two Rooted Max 2nd Molars?

How many of these do you guys and gals come across?  I have had three in the last few months.
I have looked for additional anatomy, but have been unsuccessful so far.  I am attaching slides
of one of the cases.  Let me know what your thoughts are on the subject? - Joshua C. Gorman, DDS

Josh, 2 canal Maxillary 2nd molars are rare...in fact..rarer then 11% in my practice.

Typically you would want to take a very distal angled projection (30-45 degrees) and if the patient
is cooperative enough, how about a mesial?

Look at your original radiograph enlarged...I have drawn in what might be another canal system based
on the PDL...I can't tell for sure based on what I got...I'll typically take 4 or 5 post ops changing
the angle to see if I see it better... Joey D

Joshua, I have had several. If the files go out in the same angle out of the pulpar floor, it's a good sign.
Nice treatment and excellent documentation, - Thomas

Hi Joshua,

Great Case and presentation !!

I have not come across many with 2 canals, I have had one case with 4 separate roots - 2 palatal canals
( 1.4%). There is also a possibility of finding another canal at times an MB or MB2 canal within the
Palatal canal....just getting educated from various sources...(;...the possibilities are endless...

Thanks Rajiv.   I guess time will tell.  If it fails, or fails to heal,
then I know I missed some anatomy :) - Joshua
