This is my main dental assistant.  Extreme cold sensitivity lingering with hot sensitivity sporadically.
MB cusp fracture that we did not know how deep.  Cusp blew off with high speed and we had a medium exposure.
She didn’t want to try a MTA pulp cap and requested endo.

Access routine but saw a dot under the scope palatal to the MB canal orifice.  All the canals were
unusually large.  Finally diddled around with the dot until it turned out to be a MB2.  It was small
but I eventually got it to a 15 K file.  Palatal was straight line with a 0.12 Twisted file, MB straight
with a 0.08 Twisted File and DB straight with a 0.08 Twisted File.  I thought I was going to have to do
crown down on all of them but luck of the draw saw them go easily to length and come out with clean shavings.
I was a cautious with the MB2 and started with a 0.04.  It went to the apex too easily so
I used a 0.06 to get to the apex.

Sized apexes with K3s MB and DB to a 35 and palatal to a 45.  Then I did it.  Went down MB2 with a
K3 0.04 25 and dead ass ledged it.  It took me a long time to get a radiograph that separated the
MB1 and MB2 but got it.  You can see the ledge.  Strange thing was the 0.06 TF would still make the turn.
Finished to the apex with a handfile knew they merged but still wanted to size the MB2.
Cone actually went to length but filled the MB1 first.

Twisted Files, K3 files, (bucket of handfile), Epiphany with primer using System A.  Build up with Bond
It and Artiste.  This one took me three hours and some bad language after ledging that MB2.  Was a bit
different to find an definite MB2 on an upper second molar although they are not rare.
Thank goodness for a scope.  -  Guy W. Moorman, Jr. DDS
