    Mark: absolutely cool……..I will post a collage of cracks we see with the scope. The two things you notice right away are cracks everywhere and decay.

    Dr. David Clark from Washington state just has completed a cool article on categorizing cracks based on 16X mag and it is very very thought provoking. I am peer reviewing it for the Journal of Esthetic Dentistry and I think that you are going to see alot of stuff coming out that will advance cracks and their treatment before end stage disaster in the future, and most of this will be driven by high magnification technologies such as the scope.

    If you think about it all our treatment for cracks is symptom driven, wouldnt it be cool to treat these prior to them becoming sore.

    Just a thought for you……….Great pics and I will post a collage of cracks if you want to see them……..

    All shot at high mag.

    Glenn

    I will wait to see if people want to see them because they really arent “laser dentistry” per say although I have treated some of the non vertical kind with the laser before finishing the buildup.

    Cool pics ……..FUji S2??

    Glenn

    PS kudos for getting it out in one piece.

    Thanks Glenn…I would LOVE to see your pictures. More the merrier, I want to learn buddy!

    Yes, these are all from the S-2. It is such a great camera. Very easy to edit. Also, thanks for the advice on posting xrays…got it down I think.

    I just wanted to show what posts and pins do. I have another picture of a pin related crack, BUT with the scope I am sure you have a myriad of them. I would love to see them.

    Thanks,
    Mark

    Holy Cow, These are GREAT images Glenn! Thanks so much. What a great adjunct a scope is. Maybe Ron ought to think of having a magnification thread…?

    Sounds great to me………I am not big on the DT one as I get ridiculed constantly about it. PErhaps after the Dentistry Today article comes out in June then there will be more interest. Its a coming technology and it is interesting to see all the cracks.

    I see them each day but to be honest with you have never thought about them the way David Clark has but I tell you it is amazing how many I see under Occlusal amalgams.

    If Ron wants a magnfication forum for lasers or whatever , I am happy to help out there.

    Here is a classic case for you Mark. A lady with an occlusal amalgam that is sore to chewing. You think the dental plan will pay for a crown……hahaha.

    Open it up and take photos for the plan, they wont not approve it then when I show them the crack and build it up. I see this at least once per day I would guess. Usually first molars and wide restorations place 15 -20 years previous. Now I dont want to argue if the amalgam expansion does it, the bur, bruxism…..it happens that is all and patients want answers.

    Kinda cool when you can pinpoint EXACTLY where the crack is……photograph it and then show the patient the solution (crown +/- endo).

    Ray,

    Not that are well controlled–except for the Yukna histo study which is being presented at IADR this June.

    We have two more we are designing now, one at UCSF and one at UMKC.  The UMKC is a 4 quad design looking at several variables.

    I attended a Hi Tech presentation at my local dental society meeting last night in Annapolis.
    Among the five presenters was a BioLase rep.
    He had a PowerPoint presentation and briefly showed a couple of cases.
    One case was a Perio case, showing inserting a WaterLase tip to pocket , blood and “granulation tissue” being removed, while killing the bacteria in the pocket.
    He commented that this technique is better than any other laser Perio treatment because you don’t have to use any anesthetic.
    I read remarks on this board where WaterLase use equates to no Local Anesthetic. Does no LA mean better?
    In Perio treatment, we as dentists are comfortable in the use of local. In the technique he showed no scaling is done at the time of laser treatment (It is done previously, I’m sure w/ LA). Why would you scale w/ LA, let heal for weeks then, remove the pocket lining and all the healing w/ the laser?
    He also told me you can’t use an Nd:YAG in the pocket because of the “hot tip effect” and the resulting tissue charring. Everytime I talk to a BioLase rep or someone who sells Diodes, the Nd:YAG has the properties of a diode, and the Diode has all properties of a pulsed Nd:YAG.
    There was alot of laser misinformation flying last night.
    Also do Waterlase users operate without safety glasses?
    This is where DENTISTS get initial information on lasers, correct or not.
    I didn’t know what to say.

    Jeff: this is exactly the problem with many laser buyers.

    Guys like Andrew Shearon who buy after a ton of research are far and few between.

    THe next question they ask after the box arrives…….

    Who trains me to use this?

    I really think it is a shame that there is so much misinformation out there. One of the things I like about Rons site is that there are some very very good Biolase users showing me how they use their machine. You show me your Opus dent, I have the Delight.

    As for soft tissue there are so many manufacturers out there and so many products that there is room for all of them and they all work.

    I think that there are better lasers for soft tissue applications than the erbium yag that will do a better job coagulating.

    I talked to Christopher Schmid today from the Laser Institute for Dentistry in Toronto Canada today and we talked about a gentleman who was doing a demo for the Delight and had a HUGE class v with very inflamed tissue that he wanted to do the soft tissue without anesthetic with the Erbium. Chris asked me what settings to use………

    I told him……….

    Try a soft tissue laser.

    Its not fair to expect reps to know all this but there is a TON of misinformation out there which the sales reps speak like they have used the laser for 5 years on patients when they have NEVER used it once themselves. They speak with experience of the competitors when many dont even know what the competitors look like and have never turned one on let used one.

    Its just ridiculous. Post the name of the guy and let guys like Robert send them a little email about it.

    Its not reserved for Biolase, but for all companies.

    Tell us what your product can do…..

    Stop badmouthing the competition and learn a little about laser physics and laser safety before spouting off that you know it all.

    THe part about not worrying about laser safety really worries me.

    Oh well………..c’est la vie (thats life)

    Hey Ron and Bob,
    JCP is a reputable journal in the perio world. This is a good article to keep around for the nay sayers. Also a possible model for a comparable study using pulsed nd:yag. Just a thought.

    Hi Mark & Glenn,

    Nice documentation of cracks in teeth. I see them all the time even without any magnification. Hoping to get into this soon though.

    Are you using scopes as well, Mark? The images look magnified.

    Great posting on cracks!
    Glenn, I am not getting a scope! I am not getting a scope! I am not getting a scope! Well not just yet! smile.gif
    So much to buy to improve dentistry! So hard to budget and stay within those limits!

    Hi Bob

    Re: the laser frenectomy- and the use of anesthesia. Do you use just topical or inject a few drops of local into the surgical site?

    The most important things for me are to keep the patient comfortable and do quality dentistry in a relaxed atmosphere… so I prefer using some anesthesia to assure patient comfort

    I bought TAC Gel and am wondering if this will provide sufficient anesthesia for the surgery. It seems quite potent- I used it today on an endo case. The patient had deep caries and when I touched the pulp she felt it a lot, even though she was profoundly numb with an Septocaine block and interlig Septocaine. I took a small ball of cotton, saturated it with TAC Gel and placed it on the exposure for about one minute. I then was able to do a direct pulpal without pain and she felt nothing for the entire procedure.

    Look forward to your reply

    With thanks, Jerry

    I couldnt agree with you more David. It is getting exhausting staying up with technology but I will say this that the scope is really valuable in the practice as I honestly use it for every single patient for almost 100% of the procedures. I might not use it for anesthetic or rubber dam placement and sometimes not for the placement of the matrix band in the maxilla but almost for everything else.

    For lasers it really helps alot with seeing what you are doing. Magnification is essential in my humble opinion to do a great job with the laser. Scopes are an added bonus, I truly believe in my heart that both the magnification and the illumination both help with making the dentistry better.

    We all still make mistakes….I had an accidental exposure yesterday on a little 5 year old who wouldnt hold still. I was trying to go fast with a 400 micron tip and nicked the pulp……..silly on my part but accidents still happen but with far less frequency with the scope.

    ALl the best and thanks David………your comments do fall on deaf ears (or in this case blind eyes!!)
