Glenn van AsSpectatorHi Al: I couldnt agree with you more, the fact that healthy skepticism is good, but venomous posts which you would never say to a person if you were standing talking to him, but you are so glad to do if you have the computer sitting in front of you have no place in civil discussions.
I am under the weather today and the Nyquil is taking effect………gotta go and thanks for your support. It means alot.
Glenn
RodSpectatorWell, as being ‘the other guy’, I’ll chime in. First, “HI EVERYBODY!!”
Glenn and I have spoken about this in emails. As I told Glenn, I went to the office the next morning after our original discussion, all excited to cut some porcelain. I got out a few broken PFM pieces that we had in the lab, and fired up the Waterlase.
No dice. NOTHING!! Really pissed me off, because I KNEW that I’d used the Waterlase on porcelain before. All were on chipped veneers except one 6-unit PFM bridge.
In fact, the fella with the bridge was in last Monday. I took a look at where I’d repaired the chip. He had originally broken off the corners of #6 MI and #7 DI that necessitated the repair in the first place. I did not originally make this bridge. The bridge is about 5 years old.
The repair looks great, and like I said, I had repaired it after shaping and creating some mechanical retention with the Waterlase.
Frustrated that the Waterlase wouldn’t touch the PFMs I was trying it on, I called my lab to ask. I really got no good info from the lab, but we discussed that it might be some sort of difference in the porcelains. Hmmmm.
Anyway, thanks for the invite to join here Ron. Maybe I can “hype” some lasers here too, huh? LOL!!!

RodSpectatorHi Guys,
This bone removal stuff with the laser is really fun, isn’t it?
Actually, the ‘papilla flap’ thing that Glenn was mentioning is something I’ve only done once. I did it that way simply after the fact. The crown had already been placed. Foolishly, I thought I’d be able to get away without crown lengthening on this particular case. Wrong.
So I had no choice but to reflect the facial papilla. And it worked great. Had the patient back for post-op on Thursday, and she’s doing very well.
Normally when I do the interproximal crown lengthening, I do no reflection of tissue. And the cool thing is that even though visualization is not the greatest, since the tip is end cutting, if you simply angle the tip appropriately, and run the SIDE of the tip along the side of the root (of both the tooth being prepped and the adjacent tooth), you can pretty much do a great job even with some of the limitations of visualization.
And as I’ve said before, the incredible thing is the rapid reformation of that interproximal papilla — incredible.
Ron — like you, I don’t bother trying to coagulate with the laser. I use CutTrol in the Ultradent Infusor syringe, and the bleeding is stopped in two seconds. Very simple. I personally agree with Gordon Christensen, and like the CutTrol MUCH better than the similar Ultradent products.

Robert Gregg DDSSpectatorGood to see you Glenn. Watch that burn-out. Take care.
Ron, is the etch survery device specific? Erbium versus Nd:YAG for instance?
Great forum for users. Nice job keeping it fresh Ron.

Robert Gregg DDSSpectatorHi All–
Great question!
The early hospital protocols develped then later borrowed to develope the Curriculim Guideline for Dental Laser Education in 1992 included this prohibition of using high powered lasers with OXYGEN.
This was because patients who had been intubated with 100% oxygen were killed when a CO2 laser hit the intubation tube. Hence, no lasers to be used with O2.
When writing the Curriculum Gidelines for dentistry, that provision–it may have been ANSI or the American Hospital Assoc. (AHA), I don’t remember–was left in.
That proscription has no basis in science, the literature or clinical experience when using Nitrous Oxide that is not combustable. It’s prohibition was overly cautious and misunderstood. I’m a little surprised that is still being reported.
As I understand it, correct me if I’m wrong, oxygen is combustable, nitrous oxide merely supports a fire, but is not combustable.
That’s what we teach in our Curriculum Guidelines for the Institute for Advanced Laser Dentistry.
I’ve used N2O2 with lasers for the 12+ years I have been using all sorts of lasers without worry or incident–including “free-beam” carbon dioxide lasers.
Now, when we have our patients on 100% O2, we aren’t using our lasers at that point, right?
In any event, the oxygen in the room is not enclosed as it was when that patient’s intubation tube was lased, ignited the oxygen, exploded and burned their lungs.
Our lasers won’t ingite any extra increase in partial pressure oxygen in the room, anyway!
So….relax……inhale……and lase away!:biggrin:

Thanks Bob, but its the guys who participate that keep it fresh.
I think you just gave me an idea for my next poll!
PatricioSpectatorAl,
Thanks for your comments. I need to get organized with my tips. I can see you guys have special tips for this and for that. I think I am ready to begin to manage my tips better. Thanks for the help.
I would normally follow your tissue suggestion as it is now easy for me to remove tissue of this type. I guess I misjudged the tissue mass before banding in this case.
Pat
PatricioSpectatorHi group,
I’m with Al. I do not have problems with continuous running but I have a lot of standbys when I am just getting under way. The foot controller seems to be a little too sensitive. By the way, boy are you guys hansome. How does an one add a photo?
Pat
SwpmnSpectatorWelcome Rod!!!!!
Knew you’d chime in here eventually!
Al
RodSpectatorThanks Al — and thanks for the other advice too.
Rod
Janet CenturySpectatorThanks Bob!!
Good thing – just got 6 restorations done on a 5yo at a single visit with my friend nitrous.Janet
Glenn van AsSpectatorHi Rod…….great to have you here. I want to commend Ron for his web site as the primary emphasis here is on learning new techniques in laser dentistry regardless of which laser you prefer. I think it is a great place for learning and for me the personal attacks so often found in other forums arent seen here.
Welcome Rod………its great to see you here.
Glenn
2thlaserSpectatorGlenn,
Good to hear from you. Have you tried your laser on porcelain yet? Just wondering what your results were if you did. Obviously you have the adavantage of the scope, so you can REALLY see more. I am really interested to see what you see.
Mark
2thlaserSpectatorPat,
Sometimes a “dead soft” matrix band helps in these areas. Sometimes, I use a small spoon excavator to remove some of the gingival and lingual axial walls near the gingival floor, to accomodate the differing anatomy we sometimes find there, especially on the mesial of upper 1st bi’s. This then allows the band and wedge to conform to that anatomic problem.
Great posts!
Mark
Glenn van AsSpectatorHi Mark………it never has cut porcelain in my hands.
I will post some pics soon.
I am sick at home with the flu, first time in 10 years.
Yuck.
Will try later this week when I feel better.
Cya
