etienneSpectatorHi Jeff
Nice case!I was just thinking…you were using 180mJ/pulse through a 360micron fiber. If I wanted to achieve the same result through a 300micron fiber at a pulse length of either 50 or 300 microseconds (in comparison to your 100 microsec). What should my energy per pulse be? Interesting thought. I suspect that it is not as critical as all that but interesting none the same.
Thanks for posting your case!
Take care
Etienne
etienneSpectatorHi Glenn
I really appreciate the fact that you post your complete settings with your cases, not just “use the setting for crown lengthening” or something!! In order for somebody to understand what is going on during the procedure the full settings are indispensable.
Take care
Etienne
Glenn van AsSpectatorHey Etienne , thanks for the kind words. I am in NY right now and lecture on Tuesday then it is off to Dubai for a day or two.
I will post a case soon on here with closed flap once I get healing photos. It looks ok and I had a specific reason for doing it.
Gotta run but thanks for the kind words
Glenn
DrDanSpectatorJust an update…..for what it’s worth. Since my last post on this thread (Nov 14)…we’re batting a thousand with “laser analgesia” for removing old amalgams. Haven’t had to grab the syringe for several weeks now.

JanetCenturySpectatorLooking forward to CE in 2006 (both laser and otherwise). Bearing in mind that I have already committed to the Townie Meeting March 30, Millenium Meeting Februay 16, Chicago Midwinter February 16 and an Endo-Scope Course in Chicago March 3. I will definitely go to AMED again, and I have to spend some time on the next level of ortho. Whew!
I need some more laser education, specifically hard tissue, more specifically my DeLight (or Versawave later). Is Hoya Con Bio doing any advanced classes? I thought Glen Van As did an advanced course (with Nash maybe?) but I couldn’t make it – anyone know if he is doing an advance laser scope class anywhere?
And is anyone going to the ALD this year? I really enjoyed my first one, but had to skip last years’. I’m kinda frustrated looking at the site because there is still no details on courses or speakers.
Any other courses out there? Thanks – and I’d hope to meet you at some of them
Kind regards,
Janet
BrianSpectatorWhat is the difference between the 񘘐 and the 񘴘 maintenance agreement with the waterlase. I can’t sell mine, so I might actually look into getting it working again.

Hi Janet,
I got an email today that listed the following for ALD:SOURCE 2006 INVITED SPEAKERS
The following five featured researchers and academicians are scheduled to present in Tucson. These speakers will be amongst more than 40 expected speakers:John D.B. Featherstone, M.Sc. Ph.D, Professor, Department of Preventive and Restorative Dental Sciences University of California, San Francisco on the topic “Caries & Prevention with Respect to Lasers”.
Paul Giovannone, CDT, Biogenic Technical Instructions, LLC (BTI), on the topic “Enhancing Dental Treatment Outcomes Through Laser Welding”.
Andreas Moritz, MD, DMD, Dept. of Conservative Dentistry, Dental School, University of Vienna on the topic “Lasers in Endododontics – An Overview of the Literature and Current Research Studies”.
Wolf D. Seka, PhD, Senior Scientist and Associate Professor of Optics, University of Rochester Laboratory for Laser Energetics on the topic “Laser Ablation Mechanisms in Hard Tissue and their Clinical Relevance”.
Sofia Tranæus, DDS, PhD, Department of Cariology and Endodontology, Institute of Odontology, Karolinska Institutet, SWEDEN on the topic “QLF and Other Diagnostic Tools”.
See you there!
doctorbruSpectatorJeff,
What setting do you use to disinfect dentin, remove caries and etch ? Is there any scientific evidence this really works ?

BenchwmerSpectatorBruce,
I am a Kanca believer. My pulp caps for the last 15 years have been acid etch, dentin bonding agent, then flowable composite, then hydrid composite restoration.
Six years ago with the PerioLase, I would lase exposures to stop any bleeding, remove any remaining caries and disinfect 3.0W 20Hz 150usec. Then acid etch and DBA.
With self-etching DBA I go right from lase to DBA to composite. Now with the MVP-7 I use 3.6W 20Hz 100usec.
Read Kanca’s literature for his science on dentin bonding or Bertalotti for the West coast guys. The Nd:YAG has FDA clearance for dentin caries removal. The laser use in deep carious lesions, led to use when a small exposure occurred during mechanical caries removal. Success is measured in a week for pain or lack of and at nine months for vitality.
Studies on Caries removal check the Joel White studies from the early 90s, Bacterial reduction of contaminated dentin, pulpal responses to Nd:YAG on dentin, etc. There is a bibliography in the Day 1 book from Laser Boot Camp.

Glenn van AsSpectatorHi Ron…….I am giving at least one lecture (a one hours lecture on exposure of orthodontically impacted soft and hard tissue removal with lasers). I think its Thursday from 3-4 and in addition I more than likely will be doing another hands on course with Global and lasers!
Alot of work but alot of fun as well.
I ran into Ron Kaminer when I was leaving New York and others as well, and I hope to get a chance to see everyone in Feb at Bob Greggs (I saw Del and Tim Grenz as well as Dianne Sharp at the Greater New York) and hope that all is well with you folks until we get a chance to run into eachother again!!
Glenn
BenchwmerSpectatorEtienne,
Sorry so late with reply, this is the third time I composed this, only to have it lost into cyberspace.
Try #3. I think all is well.
I have never used a 50usec pulse. As long as it will ablate the lining of the Venus Lake it’ll work. The 300usec pulse would produce more thermal damage to the adjacent tissues. The 300micron tip would give you more than a 25% increase in power concentration over my tip,so I would use 3.0W 20Hz 50usec.
Tissue necrosis to adjacent tissue needs to be avoided, enter the lesion, destroy the lake, that’s it. Less is sometimes better.
Jeff
doctorbruSpectatorThanks Jeff,
I spoke with John Kanca at his Apex booth at the GNYDM yesterday and he and Gerry Geister(spelling) told me that they were planning on releasing a paper showing decreased bond strength on laser treated surfaces.
John is one very smart puppy. I ordered his simplicity, interface and anchor cement to try. Everyone is raving about his materials.Thanks for your response, very informative.
Bruce
etienneSpectatorHi Jeff
Thanks very much for your thoughtful reply!!
Much appreciated
Etienne
PS: I’ll send you pics of my case when I am done
BenchwmerSpectatorBruce,
I like using air abrasion after laser to prepare lased anterior teeth for bonding. It removes the “white residual enamel”, gives me the perfect clean surface to etch and bond or bond with a self-etching DBA. I have gotten away from Kanca’s endorsed roducts, but have maintained his bonding principles.
Jeff
doctorbruSpectatorJeff, Maybe I should dust off my Kreativ Mach IV. I got away from using it when I purchased the waterlase a few yars ago. Also did not like it when they started selling grey powder only. Interestingly, John kanca loves air abrasion.
