bis-phenol A has been a precursor in the synthesis of bis-GMA. It can be made from BPA and glycidyl methacrylate. Of the two, the GMA is far more toxic alone.

This is probably somewhere within the forum already, but I didn't see it and I think it's important enough to ask again.

I recently got an alert from my dental association to be aware of the newspa ...

I have been using flowable (Tetric Flow).

I prepare, clean and apply Simplicity - This layer is cured for 10 seconds as close as possible.

Was the initial hesitation over this recommendation a trend for dual cure materials to change shade over time? Is it something inherent to the autocure component that makes this shade change inevitab ...

I just got my Ultralume 5! I can't wait to try this bad-boy.

I've been trying to pulse cure with my existing light, but I was unsure of the output, and I'm not sure I ever really had the techniq ...

I was talking to my Schein/Arcona rep and he told me they now have access to Ultradent's full line. I'm hoping to have an Ultralume 5 and Viscostat clear soon.
