    Mark,

    Ron said WARM!!!

    Just kidding. I know it’s beautiful and warm in the summer “upthere”.

    Glenn,

    Tissue welding works. Well establish principle of warming the blood to create hperthermia, not vaporizing it. Takes place when the blood is warmed to 50 degrees C.

    (pssssst, that’s what the long pulse duration are used for when you can’t simply defocus in the deeper pockets and you want tissue welding down deep=hemostasis)

    I am having a “silly” problem.  When I have the insert for my loupes (for the Erbium) I cannot control the fogging.  I don’t have this problem with the loupes alone.  Advice?  

    Have you tried “defogger” that us scuba people use?  Just use some liquid soap before you insert them, that ought to work.  Wash them off with soap, rinse and air dry.  If you wipe them off, you lose the “film”.

    Of course you can always use the “natural” defogger like us old divers still use–aaaaauuck, thwap!!  Rinse and air dry.:cheesy:

    Could this be just the initial excitement of using the laser? It should resolve with time!!

    Then again, David may just be right, and it will pass with time!

    Cheers!

    Glenn, Cool case. Please don’t take this wrong! One of the cosmetic problems with this type of case is the difference in the translucency between the porc and the composite. Most of the time it is not a problem as the lip will hide it.
    Try a base layer of something opaque like A3 opaque Kolor +Plus from Kerr. Make a nice translucent composite look like and opaque porc.

    Bob,

    Sad to see and predictable given what’s happened over the last 2 years. Can tech support and service be obtained for ADT equipment when they finally go under?

    Lumenis finally found a new CEO (with no med tech experience) and only time will tell if they can clean the house of existing upper management and recover credibility. The stock rebounded a bit however I have my doubts that they can reverse the downward inertia in sufficient time.

    My technique which is approaching one year:

    1) Erbium laser for caries excavation. No slow speed round burs are used for carious lesions that can be safely treated with laser(i.e., no adjacent metal margins). Bevel placed with Erbium on margins of restoration.

    2) Clearfil SE(Kurraray) self-etching primer applied to enamel and dentin in two coats with agitation for 30 seconds. Evaporate solvent, apply adhesive and light cure.

    3) Flowable composite De-Mark(Cosmedent) or Perma-Flow(Ultradent) applied to gingival floor and out to margin against matrix band on Class II’s.

    4) Incremental placement against facial/lingual walls or matrix band with 3M Z-100 or Ultradent Vitalescence posterior composites. Two mm increments cured for only 10 seconds with commonly used halogen curing lamp.

    Nice use of the Er: YAG for osseous crown lengthening on mesial of molar.

    Some non-LASER questions:

    1) I noticed the endodontic treatment and mesial curvature towards apex of tooth #20. Atraumatic removal of root fragments such as these can be frustrating. Once you removed interproximal osseous on the mesial and distal with diamond, did you simply use an elevator to rotate out the root fragment?

    2) Are you viewing the treatment field through your microscope while you are performing an extraction?

    3) Excellent provisional bridge. Is that an auto-cure composite(e.g. Integrity or Luxatemp)?

    Thanks David………great advice.

    WIll try it next time. Makes sense too.

    PS I have heard of this for occlusal accesses in previously crowned teeth.

    Oh Allen you always ask the greatest questions.

    I will be brief………I am starting a DVD production tomorrow and need to go read my manual for my new digital video camera that we are going to hook up to the scope.

    1. This root was a bugger to get out. I broke it off one more time before I got it all out. IT was tough to get a bur down all that way. I like the small diamonds for troughing (needle nose sort of) around the roots but in this case it took a while to get it but I could see it the whole way down.

    2. Yes I am viewing the treatment the whole time through the scope. The illumination and magnification are important for visibility . Remember flaps are for access and visibility and most of the time if I can get at the roots , I dont need to raise a flap . Like in this case.
    I also find that the video output from the scope allows me to have the opportunity for my assistant to suction EXACTLY where I need it. She can see from the monitor positioned for her where to be an where to not be.

    She is an awesome assistant and is really a big help in tough ones like this where she is suctioning out of my way and right where the bleeding is. She gets a good idea of where to go from the macro view (she looks at the operating field ) and then fine tunes it by going to the micro view on the monitor.

    She never stands for suctioning and I never have to grab the suction……..she is that good.

    As for the provisional ……thanks. I use Luxatemp I think (sheesh I should know) but used a template made from the original teeth in a suck down shell. Placed gelfoam in the socket and then added composite to create an ovate pontic site.

    Its one of those ones in a gun……..Luxatemp I think and then once adjusted we sandblast and place optiguard or a varnish overtop and cure it.

    THat one actually wasnt one of my best.

    Thanks Allen………you always make me want to post again.

    Hi Glenn,

    Very nice handling of the tissue in extraction of premolar and prep of molar. Was the option of immediate implant to replace premolar not appealing to patient? Too bad the first premolar had to be involved.

    Don’t mean to doubt your treatment planning. Just hate to see prepping of a virgin tooth.

    Hi All,

    Is eye protection necessary with the Waterlase? The rep says it is not needed. How can this be, if it is an Erbium:YAG like the Delight?

    Hi Andrew………no offence taken.

    good point about the implant…hadnt really thought about it to tell you the truth.

    The crown came off on the molar a while back and the margin was on amalgam my associate mentioned to me.

    I knew that I had to replace that crown as well as extracting the premolar.

    An implant was a definite alternative and one that I should have thought more about. I dont know if this patient would have taken the chance as he is very conservative in his approach only going for dental plan coverage.

    I will next time take your input and see if the patient wants implants, but I was kinda thrown off because I didnt originally see the gentleman but my associate did and scheduled him for crown lengthening.

    You know what I got another crown lengthening diagnosed today with a fracture premolar…….there are alot of them if you go looking for them and dont ignore them………..amazing and easy to do with the laser.

    Thanks Andrew…….I am not to big to recieve constructive criticism for the cases I post……..both you and Allen did that and I will be better prepared in the future…….

    Thanks alot for the input.

    You should wear eye protection, there is argument about the safe distance that is needed to get away from the laser ( 8-14 inches is one estimate) but remember this that the laser energy from the Erbium YSGG laser is absorbed by water in the cornea and lens……..

    Is it worth the risk. I wouldnt take the chance.
