Actually it was the "7th" versus the "seventh" in the URL string but no problem. Glad I could help.

As to the energy flow, it could very well be true but I'm not convinced that's the case. 1st, that's only one site's opinion and I've not read or found another site or opinion yet that backs it. 2nd, most composite materials are very much the same in composition, varying only by a few small percentages of trace elements. In the case of DiamondCrown versus the others, it supposedly does not have the BISGMA which may be a big difference or not, I don't know. And that claim is only a manufacturer claim. So who knows?

Nevertheless, all this is still very good information and something to think about, so thanks for sharing.

Best,PB
