Hi John. I'm down at Pankey this week. We just had a lecture from Harald Heymann. Great guy, great lecture. I asked about Simplicity. He said he has not tested it as of yet. Harald had very complimentary things to say about you, but no info on Simplicity. I understand you have numerous invitro studies, but any studies like the ones like Harald does down at UNC? Thanks again for your time. PHIL

I have been trying for a long time to arrange a day to do some in-vitro testing with Harald and Ed at their place, and I'd LOVE to have an in-vivo study run. Thing is, they cost a bloody fortune and we are just not highly capitalized enough to afford it just yet.

So please order by the case and we'll secure a study!

I think Surpass will be something they'd really want to have. Students won't be able to screw it up.

Yes John, Harald said something about $60,000 and how that might be the hold-up. I'm doing my part to help you all out in that department, but 60K is a lot of money.

If I recall correctly(late night involving medicinal alcohol), Harald said something about self cure core materials not bonding to agents with a low pH. Is that why you recommend placing a thin layer of DUAL cure material down first, then cure, then bulk fill? Thanks again, PHIL

Here's a secret- it's not the low pH. When I apply Simplicity to ceramic I can make any self-cure or dual-cure amterial stick to it famously all by itself.

On dentin it's tougher. I think it's about the permeability. That's why I recommend either placing the thin layer of something first, light-activating and then adding the rest, or adding the additional coat of Sim 2 following the usual application.

For cores it is best to do it the first way because the bond strengths develop most rapidly.
