Hi Glenn,

I like this case.

Your photos gave me the push to treat my hygeinist with a similar crown which exhibits cold sensitivity and is unresposive to all sorts of conservative treatments from occlusal adjustment, to fluoride potions, chlorhexadines, Sensodyne, etc. We cut off the crown (new Brassler tapered diamond) and it looked the same as your photo at the offending margin. Especially the axial wall staining. In addition it had a black stain on the flat butt margin. The previous prep and crown were great but I think the lueting technique failed at the interprox margin and the ensuing leakage gave rise to the symptoms: cold senitivity and now that I look at the tissue, a chronic inflamation in a very motivated plaque manager.

Nice posting. Thanks for sharing.

ps: cutting off the all ceramics is very difficult and the only method I use is to divide with a diamond as you have shown and then use a jacquette to pry one piece against another. The fulcrum piece usually stays and I have to divide again, and agian until I feel the remaining piece is small enough to grind it all away quickly. It is the fastest method for me to accomplish a tedious task. Just rethinking the methodology has me wondering if I were to make three intesecting cuts (6 pie pieces) I can use the prying instrument to step around the tooth removing smaller pieces with less difficulty and more effeciency.

Kirkpatrick’s time and motion principles says do all you can with one instrument , then go to the next without going back to the previous.

I would love to hear of another method to try.

Hey Ray,

Good to see you. Nice reference material as always.

Is that article suggesting I can create HK with my free-running Holium YAG?

Bob, the Kodak patent does not specify the phenomena as being unique to any wavelength in particular although they did refer specifically to Biolase’s patent and Er,Cr:YSSG for its high water absorbance and used it in their experiments. If your question is about the Japanese work, I am not sure why the SWRC folks chose Ho:YAG for their experimental setup. Could be finances – you know how research gets funded in grad schools. I am surprised that their apparatus worked as well as it did using a lousy wavelength. Makes me wonder what the apparatus could have done with an Er source.

Hi!

Since I no longer use my Diode, due to my purchase of my Periolase II NdYAG, I have a Diolase ST for sale in excellent condition. I purchased it 3 years ago , haven’t used it in over a year and would let go of it for &#368,000: about half of my purchase price.

To the seller, I will give a list of the protocols that I have used for the FDA approved procedures so that their will be no guessing as to how to use it!

Hi to all,
Had one of these today as well. Frank Yung has done over 100 of these vital pulp caps with the laser…diode 980nm I believe. He does large pulpotomies with them as well and uses dycal to cover. Reports 80% success long term. I tried this today, pictures still in the camera but will post with notes. I think using MTA would be a better “cap” as it sets even with moisture and allows tissue growth. My case was a near carious exposure, but vital pulp with constant pain. I prepared her for the endo, but we thought we might try this instead. I will keep you posted.
