Subject: [roots] Huge single canal in lower second premolar

That is a lower right second premolar retreatment.

The RX before is deceiving and one could think it's just another canal.

Took out a single .02 gutta ( may be it was # 30 - a very tiny one ) 
placed inside, what appeared to be, a huge oval canal. Fortunately 
for me it was relatively easy this time to get through the
Russian red paste.

Rest was a lot of shaping with hand files up to #80.02. It was a lot 
of rinsing, too. Placed CaOH for one week at the end of first visit.

During second visit (today ) - removal of CaOH, rinsing again with 
lot of 2.5 % Hypo, 2 ml 17 % EDTA, again 4 ml Hypo and finished 
rinsing with 4 ml 3 % hydrogen peroxide. Filling was done with 
bioceramic sealer iRootSP - first used  Lentulo filler at 300 turns 
to get the sealer inside such a big canal, then used hand spreader 
to disperse the bioceramic on canal's walls and finally "condensed" 
the ceramic by inserting two gutta percha posts - one # 35.06 and 
one # 30.06 - tips reaching one mm short of  WL. Final mm of this 
# 80 canal is filled with bioceramic only.

PA lesion imho. - Valeri Stefanov
