Subject: [roots] middle mesials
Nothing special.....Some basic stuff on troughing and how the floor
should flow into the walls. - Fred
Fred: On the contrary it is very special.
Is there anything that alerts you to look for MM other than troughing?
should we take in to consideration, how far apart the MB & ML canals
are for instance? Is this anatomy discernable on the pre op x-ray?
wire film? post op? and finally, how would you recommend filing this
canal so it doesn't get blocked or ledged?
BTW, are you using 950 or the A95? Very nice pictures. - ahmad
I connect the dots and trough a few mm's on every case. On the angled
pre-ops, if the mesial root looks especially wide, I may be a bit more
aggressive....but I always stay on the line and I am always cognizant
of the furca.
When you look at Hess's work from 1928, I am humbled by the simple white
lines that appear on my post-op radiographs. - Fred
Yes, anatomy can be wild but even the wildest can be overcome with an
understanding of shape, access, and development of a thoughtful strategy
that allows debridement and obturation of the clinically significant space
leaving only the most minute entombed crypts remaining and unlikely to
cause recurrent pathosis. Thank you Sir Walter for showing us what the
anatomy looks like and thank you Herb Schilder for showing us how to
treat it! - Terry
I'd add...Thank you Brown and Herbrason.....the 3-D Micro CT is gorgous
for showing this on the computer...Joseph Dovgan
Terry, I agree with you. A strategy on creating pathways to the canals
is required in order to debride and disifect them. Proper magnification
and illumination to see the subtle color changes of the "Road Map" is mandatory. - Fred
