Hi David and Al,

Good application for geographic tongue. I suppose this will apply to most cases of stomatitis.

How long did you paint the area for?

Thanks for sharing.

Thanks Andew,

I know the principals at Biolitec well, and have for over 12 years.  I like them ALL a lot.

However, check the ad inconsistecy:

“The 980 nm Wavelength

A major benefit of the 980 nm lasers’ wavelength is the ability to cut (means vaporize) and coagulate (defined as thermal necrosis) optically – not via a ‘hot tip.’  Because absorption in hemoglobin and water is optimal at the 980 nm wavelength – as identified by physics and photobiology – these lasers’ fiber tips do not require conditioning.  As a result, laser light cuts and coagulates with these lasers – not a “hot tip.” “

Show me the “water absorption” physics or “photobiology” data……What data I have seen and experiements I have done shows NO absorbtion in water at 980nm.

“Therefore, many lasers use conductive heat via a ‘hot tip’ to prevent bleeding while the 980 nm lasers coagulate optically, providing hemostasis that is much more durable, solid, and beneficial for patients.  Also, because laser light cuts the tissue, when ablating tissue, the 980 nm lasers maintain a controlled depth of penetration and essentially eliminate collateral tissue damage.  Without charring tissue, biolitec’s 980 nm lasers minimizes post-operative swelling and discomfort.

Unlike other wavelengths, the 980 nm wavelength is neither absorbed too much nor too little in water and hemoglobin – enabling precise, char-free soft tissue ablation and hemostasis. “

What does THAT mean?  Does that mean 980 is NOT so highly “optically” absorbed in Hemoglonin and water as previously claimed?

These sort of claims are the soft tissue equivalent of Hydrokinetics (HK), which I don’t buy in to.  It detracts from the benefits and actual differences of this wavelength vs 810nm…..and stretches the credibility of the proponents and the company.  Just my humble opinion.

For the record:  pulsed Nd:YAG 1064 nm (84 nm difference from 980) has NO absorption in water–so the claims for near-infrared absorbtion in water belong only to Biolitec, as I know no manufacturer of 810nm diodes makes a “optical” water absorption claim.

Having said that, I like the Biolitec device quite a bit, and think it is one of the best diodes, if not THE best Continuous Wave DIODE device AND wavelength.

Hi Al and Bob,

The 980 does not cut well when the tip is charred. So the tip has to be placed on the surface of the tissue without pressure. The tip is not charred in this way probably because of water irrigation.

On coagulation, I use non contact mode with water irrigation.

Al, how come you have both Waterlase and DElight?
I’m thinking of either of the two, more towards Delight. You can e-mail me at kluk1@i-cable.com if you prefer to answer in private.

Bob,

Why is water absorption an important issue for soft tissue wavelengths? Seems that hemoglobin absorption would be a more important factor.

On another note, it would be great for Al to post his opinion on the strengths and weaknesses of the competing hard tissue systems.

Congratulations!!

Looks pretty good. No apparent PA lesion, canal looks about the same as the other central. Would we expect to see any reparative dentin between the composite and the pulp at 6 months PO? Does the tooth appear the same visually?

David,

I’ve been reading some on Biostim and it seems many wavelengths activate a cellular response at about 100 seconds Tx time (also interesting considering Mark C’s and others using 90-120 seconds to ‘anesthetize’ teeth) . Maybe next treatment, time the procedure and see if pain relief coincides w/ about 100 seconds. I’d also think about biostimming the other areas to see if it stops further erruptions.

Be interesting to see what happens.
