AnonymousSpectator(DLINDE @ Oct. 18 2007,10:38)QUOTEThe PowerLase ST6 is not manufactured by Fotona. It is manufactured by Lares in the state of California. The laser in question was the ST6 and is only sold by LaresDick Linde, Lares Research
Hi Dick,
Welcome to LDF!Can you tell us some more about the Lares/Fotona relationship?
What lasers are manufacturered here?
Which are manufacturered elsewhere and distributed here?Thanks,
AnonymousSpectatorND Yag manufactured by Lares
ER Yag by fotona
dkimmelSpectatorHere is a way to quickly check you Er laser if you don't have a meter.
dkimmelSpectatorNot sure how to add a series of pictures on a thread..
So hang in there. What you do take a tip holder and place PVS in the end. Cut it back 2mm from the tip. Then place a hole 4mm deep . Put composite in the hole.
dkimmelSpectatorNow fire the laser for 10sec . You must use the same tip size and settings each time to make a standard. Then check the depth of the hole made. You can make as series of these and just quickly check the laser before use.
dkimmelSpectatorThis week Jeff Jones and Keith Bateman are gone from Biolase. Their Stock is now up 10% form a low of below $3.00. Hoya has dropped off the radar and I have waited over two weeks to get tips from them. Great potential from these two companies shame they can not get thier act together.
jrfriedbergSpectatorI am new to LANAP and had a few questions for those of you more experienced
1. What was the most difficult aspect of the protocol to master
2. What were your initial outcomes like
Thank you in advance for your help

Thank you in advance for your helpI'll answer in general:
1. The first pass of the laser in LANAP is the most technique sensitive.
2. Asymetric results are the norm the 1st 6 months.
See the Private Periolase Forum for more user details and responses.
Take care,

DinoDMDSpectatorIf anyone is interested in hearing Danny Melker speak on perio-restorative procedures, I will be hosting him in Middletown NY on May 9, 2008

Lee AllenSpectatorDavid,
Very clever. So, this is a relative measure of the energy output which will show if there is a diminished delivery. I assume that you would make up several of these to use periodically or perhaps with each patient.
Considering your time, how long would it take to be equal to the $$ to buy a meter?
I like it, however. Beats the wet paper towel method.

As far as expense I just have the staff make them up when they have some down time. So for me it is not worth the cost of a meter. That and the fact the Periolase has a built in meter. I use these when ever I just don't feel the the laser is cutting correctly. What I should do is have my assistant test fire the laser when she sets it up and if there is a problem to catch me before we set the patient…..Hope all is well and enjoy the Holidays..
Glenn van AsSpectatorDino: I think that it will be an excellent course and it will be interesting to see how Danny feels about closed flap crown lengthening.
Have a great meeting, and let me know what he says about that!
Glenn
DinoDMDSpectatorWill do Glenn and Thanks!

rschmorrSpectatorany new info on this?
i've got a pt who has every sort of strange physical ailment you can imagine, including what i can only think is anug that crops up here and there, almost constantly, for the past 3 years.
her oh is excellent. no perio. ref'd to a periodontist who couldn't/wouldn't do anything. i've done some debridement on her, given her duke's magic mouthrinse. she gets improvement, but not total eradication.
i talked to her about doing 4 quads of pocket sterilization just to see what we get.
she's on bisphosphonates, i guess for early dx of osteoporosis. she's only 44 and her chart reads like a medical text for bizarre disorders.
what do you think?
dkimmelSpectatorPhysical mechanics of laser energy in living systems
Living systems often have many uncontrolled variables that make research difficult. Xiaoyan Ma studied how short pulse of 355nm light creates a plasma and sebsequent shock wave in the tissue of fruit fly embryos.
When a laser pulse of sufficient strength strikes the tissue , it knocks free some of the electrons from atoms in the tissue. The qussi-free electrons quickly rejion their atoms which heats up the tissue and vaporizes nearby water. The vapor rapidly expands outward as a cavitation bubble,creating a series of shock waves that can be detected. The process is interesting for two reasons. The cavitation bubble causes tissue damage and the shock wave formation can be used to understand the laser energy t,affect plasma generation , and to look further into how NAdh affects plasma formationhreshold needed to create the plasma.
In a series of experiments using a continuum Q switched Nd:YAG laser delivering nanosecond pulses at 532 or 355nm. They determined the difference in the energy threshold for both distilled water and fruit fly embryo tissue. The result in distilled water were similar to other research. However in tissue the thershold for longer wave length light was 38 times higher.
Plasma formation takes place in two stages. At first the laser must be strong enoungh to generate a few quasi free seed electrons in the focal spot. Then as the seed elctrons absorb laser energy they drive a cascade of ionizations that forms the full plasma. In water the seed electrons come from multiphoton ionization. In the fruit fly tissue the seed electrons most likely come from a two photon ionization of nicotinamide adenine dinucleotide (NADH). which requires much less energy. They also determined that the size of the cavitation bubbles that the 355nm laser creates is much smaller in living tissue then in pure water.
Because NADH is ubiquitous molecule central to biological metabolism the research is appicable to a wide range of tissue. In fact NADH concentrations vary greatly between metabolically active tissue and tissue excised and stored for even a few hours.
They intend to continue the investigation in three main areas – to explore laser microsurgery as a way to understand developing embryos, to explore how lasers parameters such as pulsewidth
affect plasma generation, and look further into how levels of NADH affect plasma formation. -
