Robert Gregg DDSSpectatorYep,
That’s pretty slick and easy.
Mentioning to the folks here at Bootcamp today, it was an eye-opener.
Looking forward to more!

doctorbruSpectatorCool Ron,
Was the gutta percha heated in a defocused mode and then removed with another instrument ? Or was there direct contact with the gutta percha and the fiber ? Did the gutta percha stick to the fiber for easy removal ? I tried removing gutta percha as you showed and got alot of sparking and noise that got mine and the patients attention.

JanetCenturySpectatorGreat Ron! Removing GP is one of my least favorite things.
Thank you for posting.

Bruce, I had my assistant spray water on the target as I did it. 1st time I did it w/o water and got the same sparking and noise as you did. Actually the laser energy just ‘vaporized’ the g.p. and I didn’t need any other instruments.
doctorbruSpectatorHi Ron,
Went ahead and used the water spray and viola. ..first time in twenty years I had fun removing gutta percha.
Thanks for the great info.

jgoelzSpectatorThanks Ron, totally cool. No chace of cracking a root either. Being so much easier, I suspect we’ll be doing this in more (all) canals in the tooth & a bit deeper when we do this for core retention instead of using a post.
If one didn’t mind the sparking etc, could one do it w/out water & meerely suction the vapor? I haven’t had a chance to fiddle w GPercha-laser-interaction yet. Or was with water clearly superior operating conditions?
AnonymousGuestJohn, W/O water I think there would be 2 concerns-
1. Heat build up if you dilly-dallied too long.
2. Smell and sound. There can be quite a pop sound.IMO, its just is easier to add a little water than to explain to the patient what they’ll be smelling and hearing. Also it seems like you get less black discolorization (carbon) which I think would interfer w/ the bond if not removed.
