Subject: [roots] Five canaled lower molar
This is the lower right first molar (30) that I mentioned. This one was a bear. I used half a 5 oz cup of handfiles to
get patent on this one and the distal apex was a warren of small canals so I gave up on getting a single patency. I had
finished I thought and then felt a catch on the mesial between the MB and ML. Yea, another canal that merged with the MB
but definitely a canal. Decided to check the distal again and dang if I didn’t find another on the DB tiny but went to
length on a totally different track than the DL. It did not separate in any of the films so it must have been flush with
the DL. I’ve marked it on the inverted film or at least what I thought was it.
Knowing not to try to take a rotary NiTi to length on the middle mesial, I went brain dead and let a 25 0.04 K3 get into
the MB and snapped it off. There were only two actual POE on the mesial root so I made no effort to retrieve the tip in
the middle mesial. It was a clean disinfected canal and I could fill the apex. I did fill to the file with Epiphany
This was done with Twisted Files in 0.06 and 0.04 taper except for a taking a 0.08 a bit down the DL. These canals were
small and tight and the 0.06 would only make it about half way down the mesials. Finished with the 0.04 TFs. Apexes were
sized with 0.04 K3s to a 35 on the mesial and 40 on the distal. I did not go to length on the distal but used handfiles
in the last couple of mms. Self etch Epiphany with System A. I do not think the titanium in the MM is going to do
anything other than spoil the esthetics for sharp eyes. Many would miss it but I can assure you it is there.
A tough one but a fun one. - Guy W. Moorman, Jr. DDS
