Here's the 'skinny' on this stuff:  The drill tips are about the same price 
(weren't expensive before)... but instead of lasting for one patient (or 
one crown), they will last for 1.5 crowns.  Most dentists feel this is not 
a major breakthrough but another small, incremental step in tech advancement.

Replacement filler hardens faster under blue light. (Dr. Ed could tell us
more if he's still on the list.)

The UV light has been around for 20 years now.  Now we have blue, or 
probably they are talking about plasma arc lighting.  This is more used in 
teeth whitening, as it is a bit safer, IMHO.  In terms of white bonded 
restorations, its frequency might be a bit more narrow so instead of 
'curing' or hardening the white bonded restorative material in 20 seconds, 
it takes about 8 seconds.  Again, kind of nice, but no big deal.  Actually, 
I think the BIG deal is that we now have a portable, battery-powered blue 
light which we can hand carry around from operatory to operatory!
