kellyjblodgettdmdSpectatorGreat service to your patient. Using a high-speed you certainly would have risked a root fracture due to the vibration. Nice work and thanks for the tip.
Robert Gregg DDSSpectatorHi jetsfan,
What laser and what settings did you use.
FOr years we have used our pulsed Nd:YAGs to remove the cement selectively and leave the post and surrounding dentin largely uneffected.
Usually 3.00 Watts, 20 hz, 100 usec. Then we use the Fr Nd:YAG to vaporize the gutta percha. Goes VERY quickly, right Geoff?….oh Geoff…where are you?
Love to see the pictures.

jetsfanSpectatorI am a waterlase user.
I used a g6 tip at 2.5W only 17%W as too much water would have made it impossible to see , and 25%A. The cement washed away nicely and as the tip has a diameter greater than the film thickness of the cement I did need to remove a small amount of dentin circumferentially.
Still working on the pics.
SwpmnSpectatorJetsfan:
Thanks for the tip.
How far down the root were you able to remove cement or trough around the post using the G6 tip in the Waterlase? Did you happen to hit the gold post with the laser beam and if so did you see any white sparking or flashback?

jetsfanSpectatorSWPMN,
I went about 3-4mm down the root alongside the post.Roughly half way down the lenght of the post. This seemed to give me some “wiggle room” for the post.
I can’t believe that I didn’t touch the gold post but I did not see any sparking which really surprised me. I didn’t think my hand could be that steady. -
