Time to chime in here a bit. For those of you who don’t know, I have been doing research for over a year now on endo with the YSGG wavelength with Dr. DiVito in Scottsdale, AZ. We chose to do our research with our own money, and scientists so as not to have our results skewed in favor of a manufacturer of any kind, or a school’s research agenda. David knows this. First, David is exactly right in his description of the research flaws. There is a ton more to extrapolate on here, but with non-disclosures in place, you guys have to trust me when I say the research has a “taint” in it. Secondly, I assume that the people who performed the research were NOT trained on the laser to my knowlege, and therefore probably do NOT know the protocols in using the laser correctly in a root canal system.
Dr. DiVito and I have demonstrated the proper techniques, which David has seen, in how to use the laser in a canal, but have furthered the research even more so with science that I can only show you a part of at this time.
I will make some generalizations here, that seem logical, but criticism is welcome…
If the smear layer can be removed, and no bacteria is present under Scanning Electron Microscopic view, can it be assumed that the canal(s) have been effectively decontaminated? Now I didn’t say sterilized here.Example One:
Clean, “at attention” dentin in the canal. No smear layer present, prepared with Er,Cr:YSGG laser, 1.5w, 34%air, 24% water, canal prepared with a MZ-2 fiber at 20hz, laser energy is activated on the outstroke only, 4 outstrokes of laser energy, about 8 seconds exposure time on each outstroke, with no EDTA, or NaOCl just laser energy and the water from the laser. Bacteria present in SEM?
Number 2:
Clean lateral canal, no smear layer, same laser parameters as above. Can a file with NaOCl, EDTA, 30 MINUTES of irrigation time do this? Yes, but I believe not as effectively as Dr. DiVito and I have begun to demonstrate. Can a file negotiate a lateral canal? I haven’t seen it yet, but with the proper parameters in place, Dr. DiVito and I have been able to demonstrate this phenomona, let’s just say, more than once! with the YSGG wavelength, Pretty cool huh?
I am sorry I can’t show more data, as we are just about to finish our research, and get ready for publication, but to show that the JADA article is off base is just one justification for showing a bit of our study for now. Dr. DiVito gave me permission so show these slides, and for those of you who know me, you know that my heart and soul is in this. I would NOT lead you all astray. We will have more coming soon, but those who understand research, it’s a slow and cumbersome process. Not only combined with a full practice schedule, and lecture/teaching schedule as well…
Sorry for the long post, but I have been out of town…hopefully Glenn sees this, as I won’t post it on DT. Glenn did ask me to comment on it, and David took most of the words right out of my mouth!
Lase on everyone!!

Pretty basic laser assist w/ extraction-
Preop-
Section, Er:YAG 300mj/20hz 80 degree tip
Trough bone- 200/10hz
Immediate post op-
2 twists of straight elevator and we’re done. Didn’t use nd:YAG for coagulation because site just didn’t bleed much in mesial area of socket.
Again, can be done w/o laser but just a little easier with.
Nothing happens with air, As I said ,they are just slighty tender?
