Thanks for replies

Robert Gregg DDSSpectatorHi Mickey,
I’ve found that those composites that are macrofilled (with large glass particles) are more problematic with Nd:YAG (and probably with Er:YAG) since neither cuts thru glass very well.
What it seems from my experience to vaporize best are the unfilled, the Glass ionomers, the microfilled, the “Hybrid” in that order.
Otherwise we are just heating up the glass and transferring that heat to the tooth and pulp.

PatricioSpectatorMickey and Bob,
I cut an anterior composite out today which at times gave a significant amount of sparking. What would be the cause of this sparking? It seemed to happen when I was closer to the margin. Some stain was evident in this general area. For the most part I have not had a problem when using a a good tip and sufficent wattage. Is this sparking of a type which is likely to ruin the tip?Pat

PatPat,
I’ve ruined a tip that way.Now when I’m unsure of what the composite is (how old,particle size) I try to approach at enough of an angle so that if there is some ‘flash’ it doesn’t come straight back at the tip. So far, so good. Maybe give it a try.
whitertthSpectatorI do exactly the same, Ron. You will never ruin a tip if u do it that way
PatricioSpectatorGracias Amigos.
Pat
