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 donít call the 25ís  30s and the 40ís 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 -DanS
