AlbodmdSpectatorAfter reading other people’s posts, they seemed able to achieve higher power settings than I was able. Here’s my max setting at each Hz. Does this seem about right?
30 hz-195mj
25 hz-275mj
20 hz-290mj
10 hz-290mj
3 hz-155mjRegards,
Al B
SwpmnSpectatorHmmm, I see.
Let me do some checking tomorrow before I possibly stick my foot in my mouth. I’ll get back with you on this tomorrow evening.

Hmmmmmm. Here’s what I found:
30Hz 255mJoules
25 355
20 375
10 355
3 200I’ll e-mail Tom this evening and ask for clarification. Is Glenn around this week?

AlbodmdSpectatorLooks like you got more power than I Allen. I tried calibrating it and it was going up to 80, everything else seems to be ok. Wonder what’s different.
Al B
AlbodmdSpectatorI’ve learned that the max power settings on the Delight can vary from laser to laser depending on a lot of things. Just something to remember when talking about settings for procedures. Apparently, Allen’s laser is on the statistical high end.

Robert Gregg DDSSpectatorVery true statement about the variability of power output between lasers of the identical type.
Then you need to measure at the fiber tip to be sure the energy delivered approximates the energy on the console………..
It’s is then easier to have a meaniful discussion on settings and applications.

Bob
N8RVSpectatorSpeaking of settings, anyone care to post what presets they’re using for enamel, dentin, caries, S1 & S2?
I started using L. Don Wilson’s suggested settings when I first got my unit and began adjusting to suit each situation. Then, when I started having troubles with the unit and started using a loaner while my unit was being replaced, it had different settings. Now that my new unit is up and running, it has different settings yet!
I can’t find my notes on what settings I initially used. I can probably guess and be close to what I’m used to, but at this point, I’d be interested in hearing what settings others have used successfully, even knowing that what Bob says is true — settings on units with differing outputs are mostly meaningless.
Please, humor me …
Thanks,
Don
SwpmnSpectatorDon:
I no longer use factory pre-sets with either the Waterlase or DELight. On posterior enamel if the patient is chemically anesthetized I usually crank the DELight for speed at 25 Hz 300mJoules. Unanesthetized or anteriors usually work at 10-20 Hz 200-275 mJoules. Caries, soft tissue(e.g. frenectomy) usually work around 30 Hz 175 mJoules.
I’m convinced we should be measuring power output at the tip and machine console settings have only general value.

emc85Spectatorallan, i agree.
the presets don’t work as every patient and every tooth is different. reset the buttons to what your preference for preparations are…and go!!
Glenn van AsSpectatorYes I agree as well and will also add that the laser analgesia works in some but not all patients so you have to learn you settings and what to vary when the patient feels something.
Sometimes it is better to error on the low side on both HZ and Mj than to have the patient feel something (espeically if it is their first laser filling). Once the young ones feel it you are dead.
When you use lower settings the higher levels of magnficiation are essential because otherwise you can not see if you are effectively ablating or not.
In our laser study group , several members who were using 2.5X loupes have recently purchased 5X loupes and they are amazed at how much easier doing laser dentistry is and how much more effectively ablating they are because they can see so well. Of course this allows you to lower the settings.
I have recently begun to lower the Hz settings and can tell you that if you use 10Hz instead of 30 Hz at the same Mj setting you are using 1/3 rd of the energy on the tooth, but the cutting will be slower because of the decreased repetitions unless you increase the Mj which is the energy per pulse. In addition it is my opinion that the lower the Hz setting the slower you must move the tip to allow for adequate ablation in an area.
Its interesting to see how things work, but on soft tissue, 30Hz does seem to give you a smoother cut than 10 Hz. Its nice to have the opportunity to vary both the Mj and the Hz.
Take care

dkimmelSpectatorI still love 10 Hz ! Not sure if I just get off on watching the enamel being blasted away or if it is the sound. Seems to be predictable as far as lack of sensitivity.
For the margins Glenns idea of 30 HZ and 50mj rocks. I don’t spend as much time smoothing off the margin and can make a nice bevel.
David
AlbodmdSpectatorOne thing I’ve noticed is that when I have some darkly stained dentin, it seems to come off easier using 10 hz rather than 25 hz or 30 hz. Wouldn’t have tried it until Kimmel convinced me to try lower hz and darned if it doesn’t work!
Glenn van AsSpectatorThe ability to vary the Hz for soft tissue cutting (avoids sensitivity on those class V areas where the patient is sensitive) is a great addition in my mind.
Try 10 Hz and 60 mj on your hand without air or water.
Try 20 Hz and 30 mj on your hand without air or water
Try 3 Hz and 200 mj on your hand without air or water (be careful!!)Now turn on the air for each of these……is it less sensitive.
Try water, can you still see the ablation??
It will teach you a ton about soft tissue settings.
Try a 400 micron tip and a 600 micron tip………
Its an interesting exercise…….PS be careful.

d2thdrSpectator2 questions:
First: I see many of you reporting 85-80% efficiency of you fiber-optic on the DeLight. My brand new one was running 95% upon delivery. Will this affect my settings for delivering treatment? I assume yes.
Second: Many of the posts talk about watts used. And I realize ther are different ways to get to these. But since I am so new, I am confused by this. Has someone put a table out or explained how these variations are calcutated so I can get a grasp on this quickly?
Thanks.
Glenn on the roadSpectatorHi Dennis: quickly as I am off for a run now….
1. 95% is phenomenal for the fiber, thats far better than what I got. THe settings may be lower to start but check to see whether the laser can be pumped higher manually, by pushing the mj or Hz higher after the presets come on for enamel. Usually you can. What I mean for this is calibrate your unit, press the enamel preset and once it comes on see if you can bump up the settings manually by pressing the up arrow. Not that its that important because with time and higher mags you will start using lower power settings rather than higher. Less sensitivity and eqivalent cutting when using higher mag.
2. Watts is the following (20Hz X 100 mj = 2000 ) You then divide the number by 1000 (Mj per joule) to get the wattage. Biolase had a set repetition rate on the waterlase of 20Hz so they couldnt vary it. Hence all the settings were in Watts. What you were doing was effectively raising or lowering the mj only on their machine. The Waterlase MD now has multiple repetition rates which allows greater freedom for the operator.
Off to run then to the office for an emergency darn it all.
