Thanks for the post on the Versawave/upgrade.
Just a quick question…..are you acid etching approximately 50% of the facial surface of the tooth beyond your bevel?
N8RVSpectatorThanks, Glenn, for the info. After seeing the Versawave in Vegas, I contacted them about an upgrade. Because I bought the maintenance contract (everything breaks when I touch it!), they’re making the upgrade a very tempting proposal. I was wondering if it would be worth it, and from the sounds of your assessment, it would.
Thanks,
Don
Glenn van AsSpectatorHi guys. I wasnt etching much beyond where I etched with the laser. Why do you ask?
Don: I again tested the Versawave at the ALD meeting. Neat air water controls as well ( same system as the Delight but much better control (I turned the water all the way off and then heard only air, then turning on the water I could control the spray nicely).
I like the Versawave unit alot, its nice looking and nicely put together. Take a serious look at it.

PS was a bad day today as I had to anesthetize a young nervous child for an interproximal……first time in a long time on a pedo tooth.
Oh well…….

I was just noticing how your restoration seemed to be finished….about half way up the facial. I know this is a laser forum…. 🙂
Anesthetizing a nervous child is really tough….one of my major weaknesses.
N8RVSpectatorI posted this on DT a few days ago and thought I’d better add it here to complete the process …
Update time …
OK, now that my trusty old DELight has been successfully upgraded, I thought I’d post an update for those who might be contemplating the same.
Yeah, it speeds things up considerably. At 15Hz/400mJ, the enamel melts away probably half-again as fast as at 25Hz/260mJ (my old enamel setting). I haven’t noticed much difference in patient sensitivity — maybe patients are a bit jumpier. However, the noise level is considerably higher. At 400mJ, I really could use some ear plugs! When I drop the power for the new dentin setting (15Hz/270mJ), it sounds sooooooo quiet …
So, if you’ve been wondering if you should upgrade, that’s one man’s opinion. If Hoya will do it reasonably for you, it’s worth it. I’ve been leaning toward using some anesthetic for those patients who say, “I just don’t want to feel ANYTHING, doc!” That allows me to infiltrate a bit, use the higher settings to keep from dinking around and get the job done in a reasonable amount of time. That’s when the higher settings really make a difference.
Hope that helps,
Don
d2thdrSpectatorDon,
Thanks for the update. Haven’t gotten my upgrade yet, still waiting. But have been noticing that my effectiveness increases with every use, and I’m currently cutting enamel with 10:350.
Glenn,
I’m still getting the darn black spots occasionally that I asked about in Charlotte. They just don’t go away.
Glenn van AsSpectatorHi there Denis……I am off to Orlando in 5 hours, dont know if they have internet there.
Couple of things
1. When does it happen
2. Are you using high volume evacuation (could it be charring), Best is saliva ejector or isolite.
3. What settings does it happen (ie enamel settings in dentin)
4. Is your community heavily fluoridated
5. Did you check the water flow (14-18ml/min)
6. Does the patient feel it when you have the brown spot.
7. Is the water spray optimal (have you turned you water almost all the way on with the air only a litle bit).
8. Does it happen with all the tips or only a certain one (water outlet may be plugged).The thoughts I have are either it is heavily fluoridated enamel and you hit it and it gets brown.
It is charring of the dentin due to inadequate water flow.
OR it is old bond after a filling came out as this will char brown when you hit it…..dycal and GI can do it as well to a lesser degree.
Old varnish or bond will turn brown to a degree.
Hope that helps, I will be back Sunday

Sometimes I get the impression that you really don’t work much! 😉
I think it probably is the flouride issue. the enamel is usually discolored in the first place, and it’s also only a few spots. Not usually more than just a single spot or 2 on any one tooth. It also doesn’t seem to want to ablate any mor in that area either.
Water flow and tips are fine, checked regularly. No comments from the patient, and I do not believe it’s a suction thing.
Have fun with the mouse! (Mickey Mouse.) :cheesy:
d2thdrSpectatorJust wanted to add that I finally got my upgrade last week.
Unfortunately, didn’t get to use it yesterday. Need to learn the newer (different) settings for the increased versatility.
And, I have come to the conclusion that our water is somewhat highly fluoridated, causing the dark char marks frequently. Not seeing them as often, but they’re still there occassionally. I just polish them off with a polishing diamond before finishing.
Glenn van AsSpectatorHey Dennis , let me know if you want some settings for the Versawave when I get back . I did some up in excel a while back.
I am in Tucson right now but if you email me I will try to send them.
Email me at glennvanas@yahoo.com

Fire away, anything you have will be greatly appreciated. There doesn’t seem to be much posted as to what people are trying.
unc1SpectatorGlenn,
can you send me the settings you are using for the versawave–I have been upgraded but really haven’t changed much with the new power available.Thanks,
Tal Link
Glenn van AsSpectatorSure Tal…….send me your email to glennvanas@shaw.ca
I will do it this week as I am in Tucson now.
Gotta run
Glenn
AlbodmdSpectatorHave you guys noticed better laser analgesia with the versawave, especially at 15 hz? I haven’t gotten the upgrade yet, was kind of pricey for me and decided to use that money towards a periolase instead.
2thlaserSpectatorAl,
Dr. Laurie Walsh in Australia published a study last December that showed at cycles of 15hz, the conduction of the a and c Pain fibers was decreased dramatically. David and I and others have seen the same thing clinically for over a year and a half now. Also, I don’t even use laser anesthesia that much anymore, I just cut at 10hz, per David, and go right at it. I think we are seeing a nice thermal relaxation time inbetween pulses at 10 hz that the pts. really don’t feel much…Hope everything is good in your neck of Florida!
Sincerely,
Mark
