Here’s one I got from a new ‘referral’ patient is a 21 yr old girl with
nice teeth and she’s got a section of K-file well jammed into the
mesiobuccal. Talking litigation.
Here’s the chutzpah requested to remove the file and return patient
to her for completion!
Had it out of there about an hour later, thanks to the scope,
the ultrasonic and Cliff Ruddle. The little IRS worked like a
charm - Simon Bender
I am absolutely totally amazed that a GP would send a patient to an
endodontist to remove a file they broke and request the patient
be returned for them to complete tx. Amazing!!!! - Guy
I like Jerry Avillion's approach in these situations. Not sure he
does it this way, but he's mentioned that a good way to approach
these situations is to charge the normal rct fee for the file removal.
Then you can tell the patient it's $X to remove the file, and it
isn't any more $ for me to finish the root canal - Mark
Nice recovery. I find the irs helpful on occasion, a little too
wide in others. Actually prefer a capillary tube with resin most
of the time. Might want to have a discussion with the referral
that you accept cases for comprehensive care only. You are accepting
legal risk once you get into case, whether it is partial or not.
I’ve got to admit, she has big brass ones to even ask that of you,
if in fact that is anatomically possible. - gary
Hi Simon, Fabulous recovery!
Could you tell us your steps before engaging the IRS? did you use
gates ? what ultrasonic tips did you use?
Approx how much of the instrument did you expose before
engaging etc..? - siju
Siju, Thanks I was pleased to be able to get this one out for various
reasons but it’s always nice when a plan works.
As for procedure, I pretty much went by the book :
- straight line access until I could see the file under the scope;
Stainless steel LA Axxess drills for this
- enlarged it until I could get the IRS into the full depth. I didn’t
use any ‘staged’ Gates. I prefer to use the Mueller drills, and the
red one with a diameter of approx. 1mm is just right to accommodate
the red IRS ( = 0.8 mm)
- exposed about 1mm of the file by troughing around it – my favourite
instrument for this is a #25 s/s file in an endodontic adapter in
the EMS ultrasonic. It is very slender and you can bend it so that
everything is out of your line of sight as you look down the canal
under high power. Used alcohol, narrow bore suction and Stropko to
- when I had a bit of file exposed I started ‘trephining’ with the IRS –
it has a sharply bevelled end which helps it to seat itself around
- screwed in the ‘capture’ rod and of course I could tell I had engaged
the file due to tug-back. This has an anti-clockwise thread, so I
carried on turning anti-clockwise with a gentle coronal pull and
out it came. Neat. - Simon Bender
