Subject: [roots] Dangerous Anatomy Requiring a Compromise
Sometimes you have to compromise the coronal flaring. Here'ís a tooth
with a very narrow coronal third mesial root which I just finished a
few moments ago. I was able to get a .06 cone with an uncut 20 sized
tip to the RT after some nudging but it was a tough one. If you push
on the files and try to force the shape youíll perf. If you just let
the natural dentin resistance guide you through the cleaning and shaping
process with passive recapitulations, you get an intuitive sense
when to stop before overdoing it and perfing. I can almost sense
when I'ím about to file into predentin; thatís obviously a good place to stop.
This patient was referred to me from out of town so I always do the
core in that case
Hopefully the month of CH and the multiple small file recapitulations
will have cleaned the narrow apical prep of the MB enough to push the
outcome toward success. If you are relaxed and confident
when you treat these types of cases, you wonít have problems.
If you'íre agitated, nervous, an goal-oriented about getting to the apex
quickly, it will be a disaster. I didnít have any
patients after this one before lunch, so there was no stress - Terry
