Hi Guys
This is another endo case that was completed recently after sterilization and stimulation with the Nd:YAG laser.

I use the Nd:YAG as part of my standard protocol for endo these days and am very pleased with it.

Great result. Do you use the laser with the canal dry? How long? Past the apex?
Thanks.

Hi K
Thanks for the compliment.

Yes, use the Nd:YAG in a dry canal although the laser will have a drying effect on the canal as well. You will actually hear the laser going “click” if the canal is dry.

Protocol is approx 20sec per canal while withdrawing the fiber, repeated 5 times per canal.

Etienne,

My preference is to use the laser as a heat source as well and use NaOCL and/or RC Prep to help dissolve the smear layer, pump the bleach into laeral canals and tubules. The wavelength and parameters will be effective alone in disinfecting the pathogens, but the bleach will give it an extra effect, I think.

Hi Bob
Thanks, interesting thoughts. I would love to see the results if somebody did a study on it.

I damaged the fiber on my laser and am waiting for a new one. I almost feel ashamed everytime I seal a canal while not having the laser in action!

Actually, Leo Messerindino did a study back in 1990 using an FRP Nd:YAG (150 usec) and bleach using the old dLase 300.

Results were 99.9% elimination of CFU’s with laser and bleach while either alone was only 90% reduction.

Hi Bob
Thanks very much, I wasn’t aware of it. Do you know where I can get a copy of the article? I looked on Pubmed without success.
Take care
