12 has two separate buccal canals
13 has two merging to one.
the buccal canal orifices for both 12,13 are on the pulpal floor.

Beautiful stuff, Sashi. Where have you been. I’ve seen this once
in a full blooded Cherokee American Indian. Three roots on all
lover molars. She claimed to be Creek but they were all Cherokee.

Wow Sashi, Great job. Canal location seems easier with the scope,
what about the cleaning and shaping? Does the direction of the entry
of your file determine which canal you are in, since it is very
difficult seeing thro the mirror and getting the file in?
- Mahalaxmi
under low magnification with changing mirror positions, cleaning
and shaping through the scope is easy. use small mirrors that can
fit into the space and rotate the mirror to the buccal and distal
of the tooth . this will allow you to visualise the pulpal floor
as well as the file with the stop in relation to the occlusal
reference point. its skill that need to be developed.- Sashi
i use the carr mirrors for mostly photograpghy and when i need lot
of light deep into the canal . you can buy # 3 mirrors from schein
for day to day stuff i file at the lowest mag. 2.5 in my global
scope. 3 + in seiler and zeiss 5 step scopes. - sashi
the merger is in the middle third of the root. why remove more
dentin than you really have to? what purpose that serves except
weakening the root? - sashi
You are still the MASTER!! - Fred
and i havent even shown these doubles yet (all from this year) ;-))
i could not get the silver point out from the mb of 12..
it was locked and kept disintegrating.. - Sashi Nallapati
Sashi, Very nice work as usual. I can see you also left a fragment
in the P canal that you skillfully bypassed bravo. What techniques
do you use to remove those silver cones ? - Thomas
thomas, I used every trick in the book
1. first a steiglitz
2. then a steiglitz with an ultrasonic on forceps.
3. then ultrasonic troughing around the point to create some space
to loosen the tip
4. then tried to bypass the file with smaller files till i could get
some purchase from headstroms to braid
5..then after exposing 3 mm or so of the coronal end i used a tube
with resin in it to grab it
6. then go back to step 1 through 5
7. ultimately i used a munce bur to drill it out int eh palatal of 13.
and still could not get any where with the one in MB of 12. the problem
was the silver point s were really jammed into the narrow curved canal
of Mb and was a firm fit. very long case with over 4 visits - Sashi
