UR 2nd premolar(#4)
rampant interproximal caries.
Irrev. pulpitis, normal peri-radicular periodontitis. moderate gingivitis
#4 , Carious extension to the pulp via the fracture of existing alloy in isthmus area.
worked the small curved files ( 10, 12, 15, 17<--->17,15,12,10) with Slide (=*RC-prep)
until a reproducible glide path was created.
Copious NaOCl & Anolyte in conjunction with EDTA, H2O2, ethanol, CHX.
capture zone created in .05mm segments with successive files to a size 60 up to the curve.
System S obturation.
incremental B/U with composite over a layer of Fuji GI on pulpal floor.
didn't do a good job with dry pp to remove the enough sealer, but he's been asymptomatic - ahmad





Superb, great to see your work again ! - Thomas

Ahmad, do you mean .5mm step back? Onyx-R?  awesome prep of the "red zone",
great stuff. thanks for sharing, -  Kendel

Hi Kenny G:
actually Flex-O files....but any file would do I guess.
Dave Rosenberg recommends a .25 mm preparation of the red zone.
His preps are actually 1/4 mm shorter of the MAF. I am not as talented as Dave R.
so I take the lazy way out and prep it by .5mm increments.

But you are correct , I step back from a #35 MAF like this:
40 @ 19.5
45 @ 19.0
50 @ 18.5
55 @ 18.0
60 @ 17.5
At this point you can use any method of obturation you want. cone fit or squirt.

I use the most predictable method of warm vertical with excellent length control.....
System S...-:)  -  ahmad

thanks Ahmad, I just thought you might have used NiTi hand files with that curve.
two weeks away from visiting Phoenix----looking forward to that,

I noticed Rosenberg will speak at the TDA this year, so I will go see his presentation,
- KennyG

Stropko/Dovgan put a lot of work in to their course.
And the class size is just perfect.
as much as I hate going to TDA, or ADA meetings, I may join you there.
do you know which day Dave R, is speaking? - ahmad

Ahmad, I like the Olympic relationship. Your end product looks great to me.
A little puff like that is wonderful compared to some of my results.
How do you know what material is out of the apex ? -  Dr Danny

Really nice case, Ahamad.  What did you use to restored that bomb? - Guy W. Moorman, Jr.

Fuji IX over the GP & orifice.
Tetric Ceram composite for gingival floor and interproximal walls. Luxacore for bulk. - ahmad

Ahmad this case looks like a LS case.  Did you use LS or LSX on it?  Nice case as usual - Carlos Murgel

Just a curved bent SS file with endo bender...no LS files.
I haven't seen the new LSX files...have you? - ahmad

Yes I had.  They look very good but didn't use them yet.  I am playing with other concepts
now of root canal instrumentation.  I like to learn new things -  Carlos Murgel

The human version of the lsx is not yet available - gary
