Glenn van AsSpectatorHere is another case showing the 2nd molar in the maxilla and prepping with a laser yet the mesial aspect of the third molar.
If I can prep and photograph it , I must be able to see it huh!

2thlaserSpectatorGlenn, these are great. I love the photos, and the service to the patient. I (when I get the $$, soon I hope) will be getting a scope, it’s the next thing on the list. I did a case today, just happened to show how I get the lateral decay in an occlusal. What I like to do, since I try real hard not to use rotary instrumentation, due to the obvious reasons, I try to open it up minimally first, then angle my shorter 4mm tip to get as much as possible at the dej and such, but then, I resort to a few instruments, especially a couple of microspoon excavators I am developing with American Eagle Dental Instruments out of Missoula, MT. Here are the pics I did on #29 today. http://photos.yahoo.com/toothlaser Check out the occlusal album. Let me know your thoughts, and what I may be able to do to improve my technique ok? I really value everyone’s opinion here, and definitely open to constructive criticism to get better. I did get your private email, and you are welcome. I just haven’t had time to respond privately. Have a great weekend, and yes, I WILL be taking you up on a visit to the Greater White North to see your operatory set ups, they look similar to mine already, although, I don’t have the scope yet!
From the Lesser White North, 36 degrees and rain/snow,

Out of interest, I had a similar case, and I know this is a laser forum, but I succeeded using a 0.0011″ AA tip. AA tends to selectively target the cement because the cement cuts easier than dentin.Conversely, I have found some cements do not cut at all well with the Waterlase. Probably because some of them have low water absorption for the frequency to work on. I have found GIC’s a general no go. They spark intensely (probably due to the aluminium or strontium content).
I am finding I now bounce backwards and forwards between AA and the laser, depending on what I am trying to acheive. I have found the two modalities complimentary and in some areas they overlap, so in these situations I use the laser coz I am still a newbie with it and am having heaps of fun. (Plus the patients love the wow factor. Most of my regulars are always teasing me regarding what new toy I might have next year. None are toys, but I would hate to have to go back to my pre Hitech days.)
Cheers

2thlaserSpectatorAl, Howd you do that?

SwpmnSpectatorMark:
Not really sure, was just screwing around and it seemed to work, ha ha.
Opened new topic, and clicked “Paper Clip” like Ron said. Window popped up on upper left with three slots where you could Browse computer and add image. Did that and clicked Upload. Three thumbnails showed up and it said Click Thumbnail to add to your post.
Tried it once and noticed that my images were way too big(approx. 640 X 480). Went back and halved file size. When I tried to upload again got error message which said something like This File Name Already Exists on This Server.
Screwing around again, went in and changed file names. Post was accepted.
Who knows, I’m sure Ron will help us.

Glenn van AsSpectatorMark………had a look, what a cool case.
Microdentistry is wonderful when you have magnification.
I think it is great that you did that case, without anesthetic I would imagine. Nice result, perhaps next time take a picture with a probe in there to show the depth.
One thing I notice in alot of peoples cases done without mag is that caries is still present but from your pics it looks pretty good. I dont feel comfortable undermining all the enamel , its my GV Black days but I think that I am in the minority. I always feel uneasy making a keyhole type of prep (small in the enamel and larger in the dentin).
You obviously used the sharp spoon with a good degree of success and in addition you were able to save alot of tooth structure.
What camera did you use.
If and when you get closer to buying a scope , just drop me a line and I can help you out with the education part and what to buy.
Nice stuff…….I am off to view your veneer case now.
Glenn
2thlaserSpectatorThanks Glenn. You are right, I will use a probe to measure next time. I see you do that all the time, great advise. I use the new Fuji Smilepix Pro S-2 12.1 million megapixels. Great camera, but still learning how to use it. I know the caries were gone, just a touch of “char” in the dentin on the mesial, which I removed when I went back in after the spoon technique and cleaned up. You know, talking about undermining enamel, I have done this alot, and with todays restoratives, the strength of the materials, the occlusal forces (which I check prior to doing this sort of thing), play a big role in whether or not I do this, BUT I have NEVER had a fracture, crack, or anything around the restoration so far. “Knock on wood”. Thanks for the advice, will get better and better hopefully!!!
Thanks,
Mark
Glenn van AsSpectatorHow do you like the S2 and are you using Nikon sb 29 ring flash and 105mm lens?
DO you have any full face shots?
I am interested in colors.
Glenn
Glenn van AsSpectatorHi folks: another simple thing but something which I got caught on. Patient fractured a veneer and I thought it was porcelain but was surprised to see the remaining material etch. This happens with resin but not porcelain.
I got a pretty nice color match after using the laser on the tooth and patient of course was ecstatic.Here it is ………..

gwmilicichSpectatorHi Glen. Just spotted this post after replying to the one on DT, so I thought I woudl cross pollinate my reply re the GIC’s to here as well.
I agree with everything you say. I use what is appropriate to get the job done as I see best. I can use everything, AA, Laser, slowspeed, highspeed all on the once case. I don’t get all discombobulated if AA or the Laser won’t do it all. Equally, the slowspeed and the highspeed can’t do it all for me anymore because I have got two other tx modalities that have exposed the deficiencies of the slowspeed and highspeed. Something I didn’t understand until I got AA and the the Laser most recently. You can often see this lack of understanding in posts from people that haven’t got alternatives to the slowspeed and highspeed.
As the oft used phrase goes, ya don’t know what ya don’t know.
There is one thing I don’t agree with though :-))))
Dyract is not a GI. It is a polyacid modified Resin.
I have not got hung up an trying to make one Tx modality the be all and end all. I use what ever does the job best for the situation confronting me. Sometimes I will end up using AA, Laser slowspeed and highspeed all on the same tooth to get the job done most effectively and comfortably for the patient.Back to GIC.
With all the Resin modified GIC’s, you have to mix two components together and they will set all on their own. Light will set them up as well, but that is only the resin component that sets to stabilize the material while the GIC reaction continues.If you have a material in a tube or syringe and you squirt it into the tooth without mixing anything with it, it is a resin. The polyacid modified resins will absorb water and slowly initiate a reaction, but it is not a true GIC. It will not create a GIC hybrid zone that is a combination of Ca Phosphate and F that is derived from both the GIC and the dentin. Marketing hype gets everyone confused, which is how they want you to be because we then buy something because of our confusion or misunderstanding.
The same sort of confusion/disinformation occurs with all sorts of equipment and materials. Straight up honesty would be much better for the profession, but I suppose the quest for the mighty $$$$ rules.
Cheers
Glenn van AsSpectatorHi folks: I am in another discussion with someone on another board who insists that the Waterlase can etch porcelain.
I am almost positive that my Continuum cannot do that.
Can someone verify for me that the Waterlase is effective in etching porcelain, and someone else please tell me that their Continuum cant.
Mark……..does your waterlase etch porcelain. If so can you send me a picture of this.
Thanks, it is the first time that I have heard of a difference in cutting ability between the Waterlase and the Continuum. Heck if it does effectively cut porcelain I may have to consider why one does and the other doesnt. Perhaps there is something different in the mechanism of action ………..GRIN………..hard for me to believe!
Thanks guys…..
Glenn
2thlaserSpectatorGlenn, Actually I was able to REMOVE 6 porcelain veneers with the Waterlase. I am not sure that it “etches” porcelain, but I read the thread between you and the “other guy” and I have a old PFM just waiting tomorrow for me to try it on, and take a photo of for you. Let’s see if he’s right ok? I can’t honestly say I etched the porcelain, BUT the hydrokinetics, did fracture the porcelain and get underneath it to lift it safely and effectivly off the tooth, without doing ANY cutting of the underlying tooth structure. It was really cool, I show it in my lectures on Laser Veneers.
Mark
Glenn van AsSpectatorFair enough……..I would love to see it. I dont think I can do that with the Continuum.
Glenn
2thlaserSpectatorHere are the veneer cases, 2 pics, the crown I “etched” is coming, with explanation. I don’t think these etch, but Bob Gregg says that the water gets underneath the porcelain, and I believe that is what happens with the veneers. It creates small microfractures, then the porcelain just comes right off. The crown was different, and I will explain that one when I post it in a few minutes, I have another patient to go see!
