Hi Pat,

Yep. Use it every day–like today–when I remove amalgam and replace with resin, regardless of the stated reason for removong the alloys in the first place.

However, I use……..yep……..you guessed it…….a pulsed Nd:YAG that is attracted to pigment (and amalgam) selectively over dentin when defocused.

Been doing that for over 12 years.

I don’t see any reason not to do it with an erbium, though……

Hi Pat……I wonder if it will affect the trunk fiber on your unit. Some people like Allen have been mentioning their concern for the trunk fiber when it sparks of metal.

Maybe those with the Waterlase can comment.

I avoid attempting to remove amalgam stains with the Biolase Erbium. Resulting “white” sparks/flashback may result in damage to handpiece mirror or trunk fiber.

Al,
I agree but at the same time I am lasering in a more defocused position. The particles are so small that if they did not flash you would not know they are there. They spark more than arc. Many of these amalgam preps are already over preped from the stand point of tooth integrity and if the laser can be successfully used a more conservative quicker result can be achieved.

Maybe I’ll get that service contract after all.
