New Elexion diode

[lookin4t]

That has exactly nothing to do with using a laser to treat perio or putting it blindly down a “pocket.”

Do you have anything in that application?

As a periodontist, I’m not enthused by this.

Actually there are 2 studies running:

– Short pulse with high peak power in perio vs 1 W CW
– Endo with special fibres

As you all know, it takes time to make a good clinical study.

It does take time….but what about the german language studies that you referenced some time ago? If they have been published, why not forward a copy to someone who speaks german and cam summarize a translation…such as has been volunteered by Dr. Gregg/McCarthy.

dear mkatz,

there are hundreds of studies which show the decontamination effect using 810nm in perio and endo. In the moment i have not the time to scan them – simply use google or medline to find them. All treatment protocols i know, work with 1 W CW at the fibre end and treatment times of 20s. These parameters are well known and “save”. So we use exactly these parameters in the claros.

In the moment we only use 30 W / 20.000 Hz in surgery applications. If there is evidence that high power / short pulse duration has advantages in perio and endo it can be changed by the user.

nice weekend

Olaf,

You sound very dismissive of Dr Katz, and disrespectful.

Your answer sounds like the answer of another company rep when asked for science before making claims on their new short pulse duration laser.

It is not the responsibility of Dr. Katz or anyone else to research and discover the literature that you feel best represents your arguments for your device parameters or clinical applications. It is the responsibility of the advocate to make the best argument for their device and applications.

Furthermore, with all due respect, you have tried to represent that the new high Hz and short free-running pulse duration diode is materially different in performance to any other 810nm diode as well as in its performance and tissue interactions. Then you suggest to Dr Katz and the rest of us that we extrapolate the unique tissue performance characteristics based on a laser with a completely different Temporal Emission Mode (“TEM”)?

Wavelength dependent tissue effects are greatly modified by changing the TEM. So, I respectfully recomend that you provide the data and performance characteristic of your unique device parameters, and not require us to un-earth it for oursleves.

Some of us have been involved with lasers for the better part of 15 years and seen over a dozen companies come and go…..Sunrise, ADL, HGM, Premier, Nippon, Chrys, LaserMed, Ion Laser, Excel Quantronics, Sharlan, Luxar, Xintec/Convergent to name some off the top of my head.

It always seems to start the same: bold claims are made before the clinicals are performed. I undersand. Yo have a lot of time and money invested in developing the technology and the company. Maybe you needed to invest in the basic science andclinical applications first to determine professional use viability.

I have a request. Complete your studies, then present your product for consideration.

I don’t mean to be harsh, but doctors and their patients need and deserve nothing but the best of the scientific method.

Having said that, I know Dr. Claus Neckel resonably well. I did not see him this year at the ALD meeting in New Orleans, nor last year in Palm Springs. That is unusual for him not to come to ALD with his German side-kicks, and presents his latest data.

I do have his contact info and can approach him on this topic of research and this laser.

Thanks for posting the article.

Best regards,

Bob

Sorry Dr. Katz, if my posting sound disrespectful to you, that was not my intention.

What i want to say is, that we all have some basic facts in laser dentistry. The decontamination effect of 810 nm in a number of applications is well known and published for 10 years now.

I see absolutly no need for making studies on effects and treatment protocols which are well known, cleared by the FDA and other Administrations.

There are no differences in TEM between the elexxion claros and other fibre-coupled 810 nm diode lasers when emitting in CW mode.

IMHO it makes more sense to put the money in studies to explore new treatment protocols.

For a better understanding: The elexxion claros is able to deliver the same wavelength, power, NA, TEM than dozens of other diode laser units. Thats a technical fact and can be checked easily. But this unit has additionaly the unique possibilty to deliver high power / ultra short pulses. In the moment this technology is only used in surgical applications and in controled clinical studies in the perio and endo field. If there are positive results in the future the units can easily be updated.
