True, but if they didn't get it right the first time, what are the
odds they will the second time around?
I had a fill-in assistant who also works in an office in a nearby
town have problems with a class II composite from the other
office. It went on for a couple of months, and the other guy was
talking about endo.
I redid the restoration with Clearfil SE (and a palodent ring). The
problem was solved from day one.

Irrespective of the bonding system used, it could have also been a void in
the original resin.

A void *in* the resin would be meaningless. A void between the
bonding layer and the dentin would be different and maybe a large
enough void between the bonding layer and the main resin could
have some effect.
Usually, that's just an excuse for poor bonding technique or poor
choice of materials.

Hi Steve,
This is in fact what I meant by my post. I agree with you and Dartos that
its most likely a bonding issue, but there could be this cause as well.

Have been using CFSE for some time now with very good
results and virtually no post op sensitivity.
Now about the palodent ring, what are your recommendations
and how should a newb start with them ?
Dartos - 21 May 2007 20:47 GMT
For preps that extend to the line angles: Palodent, Garrison, or
Tri-clip are great methods for gaining a little extra tightness for
the contact. You just have to get a few of each system and try them
to see which ones you like best.
On narrow preps where the preformed matrix will not go between the
teeth, I use a section cut from a standard 0.015 band and a Palodent
ring.
It I can't get a ring to stay on the tooth (rare), or if the prep
is too wide for a sectional matrix, I place a regular band, wedge
tightly, and go away for a few minutes. When I come back I'll lean
on the wedge again before beginning to fill (and use a burnisher or
contact pro to push the band against the proximal tooth will hardening
the appropriate layer of composite).
JME,
