Subject: [roots] Epiphany - new sizes

We are thinking of increasing the size range offered in our .04 and .06 points to all sizes up to 60.
That would mean including a #50 and # 55 in .04 and #45, 50, 55 and 60 in .06.  What are your thoughts on this?
Which of these new sizes do you think you would use? -  Bruce

Hi Bruce,

As I mentioned before, the sizes of the tips of the resilon cones are not very accurate. I often have to adjust the tip by
clipping them back, e.g. when I select a 30/06, I often find out that it isn't a 30/06, but a 35/06. This is one reason
why I always fit the cones in an endogauge, prior to fitting them in the canal. If I need a bigger tip diameter, I simply
clip the cone back, but if you need a tip size > 40, than the gauge doesn't provide enough possibilities, so you need to
improvise a bit. When I need a size bigger than 80, I switch to the 02 taper, and soften the cone in chloroform to make an
impression of the apical part of the canal. If the 04 and 06 cones will be available in increasing sizes, I would suggest
to leave out the smallest diameters, e.g. 15 and 20, I personally never use them - Marga

I wonder why they just don’t call the 25’s  30s and the 40’s 35. what is the reason for that naming the size different.
It must be in how they measure them - Rick carter

This is interesting.  A thread from last November suddenly showed up today - Gary

I have mentioned this often.  It is has become standard practice for us to use a 40 in a 45 prep.  I find the 0.06's are
extremely difficult to place to length even after finishing to a .010 taper.  Guy

That's funny.
I find I will fit a cone trimmed to .045 for a .04 prep (using Scott's Taper Plates).
That usually gets me within 1/4 to 1/2 mm of the file-working length.
But I susupect I spend more time than most do in rinsing and re-rinsing after the final file size is established, so I may
open it up a bit more - Wes Rampton

Wes, sodium hypochlorite, water, alcohol, water, EDTA, water, CHX.  What are you clipping.  I'm using the standard cone.
Are you clipping an 04 taper universal cone?  If so, I need to change my purchasing.  Guy W Moorman

I use standard fine-medium for most applications, and reserve the right to use anything else if the situation demands it.
The Taper Plate and a # 15 BP scalpel make a clean cut that I like.  If I need to take off another fraction of a mm, I do
so with the scalpel against a piece of paper. 
Scott Martin's new taper plates are fabulous.
He probably still has some for $100 per.  Worth every penny - wes

Subject: [roots] Epiphany recall #1

Vital, history of severe toothache, now asymptomatic - DanS



All nice cases and well documented -  Alan

for Dan,  1, 2 , 3    clap clap clap - Bart

These films are initial, final fill, 3, 6, 9, 12 months.  The case was non-vital, asymptomatic at fill and at each recall,
healing complete at 6 months.  
 
The crown is open on the mesial, this really hurts when you do a nice case by referral and see it come back with a poor
margin - DanS



is that a fiber post in the distal? nice work as always - Kendel
Bisco Aestheti-post.  Radio-leucent...:-( - DanS

Dan why you  not SEND BACK FOR NEW CROWN? - Ross

Hello everybody...well I am concerned; if you study the biocompatibility the epiphany system as a whol e, would you test
the primer as well, or is the test going to be for the sealer and the points only?!!.  Heind

Hi Dan, beautiful healing on those cases. I'm getting more and more tempted to use Resilon. 

I have known for more than 20 years that adhesion works, I'm addicted to adhesive dentistry, so it really thrills me.
But there are two open questions for me:

If the excessive Resilon resorbs so fast outside the root canal, will it also resorbe slowly INside the canal giving the
impression of a way-too-short-filling? As a matter of fact, I have seen some of my own old Apexit cases (  Ca(OH)2 based
sealer ) get shorter and shorter.

ZOE sealers also resorb outside of the canal.  That obviously does not mean they resorb in the canal.  The
only thing I've seen in many years that will not resorb is a self made mess of a sealer where a doc here mixed amalgam
powder with N2 cement.  It will last forever.  I've got a shot somewhere and can't remember who it was on - Guy

I know Resilon is retreatable, but if the intracanal bonding yields a 100 micron hybrid layer, you will have to shape a
tooth that was prepared to 40/ 06  at least to  60/06 to be able to disinfect the dentin. Otherwise you're just
disinfecting the surface of the hybrid layer.

I don't think this is factual.  When you start getting clean shaving, which I always look for at the apex
you have certainly removed the hybrid layer there.  I think if you finish a canal where you actually shape the canal to
the appropriate size you have removed the hybrid layer.  EDTA removes the smear layer and then the self etch primer goes
to work.  I really don't think this is a concern.  Heck we bond to abfractions that are shiny as a baby's butt with a bit
of abrasion and they work - Guy

Anyone who can help me get rid of my concerns? - Winfried

The films are initial, final (with a big puff), 3, 6, 9, and 12 month recalls.  The case was vital and became symptomatic
due to a crack in the dentin.  It has been asymptomatic since it was completed in two appointments with interim Ca(OH)2 -
