    See Pat, YOU can be above the curve as well. I am still struggling just a bit with the amal removal area you and Ron are having success with. I still get a bit of “antsyness” with these patients, as I remove the amalgam. Maybe I am looking for too much results, as if I am using the laser, where they don’t flinch a bit? Either way, I am still going to proceed with that area of treatment of removing amalgams. We all help eachother learn here, that is what I love about Ron’s forum. I will do my best at Dana Point. I have alot to share. It’s going to be a blast, believe me!
    See ya soon!

    Hi guys…….i dont have the patience to do alot of amalgam removals unless the patient is firm on no anesthesia.

    I do find that alot of my patients “feel” something during the process and sometimes it is a reasonable amount of discomfort but when I ask them I found.

    80% rated the discomfort as 0-15/100
    10% rated the discomfort as 15-50/100
    10% were higher and these I often had to numb up.

    I was not using the bathing technique Mark and others speak of.

    Almost all patients receiving a laser restoration for the 2nd time will rate the discomfort as lower than the first time even if the restoration is larger.

    Around 95% would have the laser again, and I do have patients who request anesthetic but the laser because they hate the sound and feel of the drill that much.

    Just some food for thought……….for those lurking or thinking about why some patients feel it and others dont.

    Hi all, thought there might be a need for a forum for sharing sources for supplies and accessories. Dr. Barr had shared a couple with me.
    Trinity Technologies http://www.lasersafety.com  recently did a custom diode filter for my Sugitel loupes. Trinity had me obtain the filter frame from Surgitel and then made the lenses to fit. These filters are almost clear in color (slight yellow or gold tint) and allow you to see tissue color so much better than the rose color filters that Biolase provides.
    The second supplier- Sventech 847-838-lase http://www.sventechlasers.com/
    Sventech has ‘laser pencils’ for diode (3 for &#36250) that are designed for use with Ultradent disposable tips(Endo EZE ref/up 345 are pliable,White mini ref/up 1247 will not transfer heat according to Sventech). The disposable tip is bendable so you can get a better angle on the fiber for access to the pocket.
    Have other good sources? Share them here!

    Hi all,
    Was doing some searching for articles on lasers and anesthesia and found nothing. What I did come across were various articles (see below) regarding the increased acid resistance of enamel in teeth that had been lased both with and w/o fluoride. So I was wondering if anyone was doing anything similar in practice? A question to the microdentistry guys (risking showing my ignorance here)- Fuji Triage can be light cured -has there been any thought (in light of studies like those below) about lasing the Fuji Triage to help along the remineralization process?

    Calcium solubility of dental enamel following Er, Cr:YSGG laser irradiation
    Apel, Christian, Graeber, Hans-Georg, Gutknecht, Norbert, Rheinisch-Westfaelische Technische Hochschule Aachen
    Publication: Proc. SPIE Vol. 3910, p. 318-321, Lasers in Dentistry VI, John D. Featherstone; Peter Rechmann; Daniel Fried; Eds.
    Publication Date: 3/2000


    Abstract:
    Ever since the laser was introduced in dental medicine, there has been a constant discussion about its use in caries prevention. Various studies have already illustrated the possible uses of CO2 and argon lasers in this field of dentistry. The aim of the present study was to examine the Er,Cr:YSGG laser with regard to potential in reducing the acid solubility of dental enamel. Thirty freshly extracted bovine incisor teeth were prepared for this purpose. The crowns of the teeth were covered with hard wax, leaving a standardized test area free. The test specimens were then divided into three groups. The test area was uniformly irradiated with 2.7 J/cm2 in the first test group and 6.5 J/cm2 in the second test group. The third test group was left untreated (control group). Demineralization of the teeth was performed over a period of 24 hours in acetate buffer solution (0.1 mol/l) with a pH value of 4.5 and a temperature of 37 degrees Celsius. The calcium content of the solution was subsequently determined by flame photometry. The results confirm a significantly lower calcium content in the test group exposed to radiation of 6.5 J/cm2 (p less than 0.025). Dental enamel seems to have increased acid resistance following irradiation with the Er,Cr:YSGG laser.

    Comparison of three lasers on demineralization of human enamel
    Powell, G. Lynn, Yu, Duncan, Higuchi, William I., Fox, Jeffrey L., Univ. of Utah
    Publication: Proc. SPIE Vol. 1880, p. 188-192, Lasers in Orthopedic, Dental, and Veterinary Medicine II, Dov Gal; Stephen J. O’Brien; C. Thomas Vangsness; Joel M. White; Harvey A. Wigdor; Eds.
    Publication Date: 7/1993


    Abstract:
    Previous studies have recorded the reduction of caries-like lesions or demineralization in extracted human teeth that had been irradiated with CO2 laser, Nd:YAG laser, and Argon laser. This study was conducted to evaluate the effects of three different cw lasers on acid resistance and demineralization of dental enamel. Human enamel was laser irradiated with either Argon, CO2, or Nd:YAG energy densities of 60 – 65 J/cm2 or 120 – 130 J/cm2. The amount of demineralization was determined in a rotating disk assembly (0.1 M acetate buffer, pH – 4.5) for 24 hours and the results determined and plotted against the non-lased control using microradiographs and computerized imaging. The amount of dissolution of tooth structure lost to demineralization in 4.5 pH acid bath in a 24 hour period was reduced from approximately 140 microns for the unlased control to approximately 90 microns for the Argon laser and 70 microns for the CO2 laser at 60 – 65 J/cm2. At 120 – 130 J/cm2 the results were: 120 microns for the Nd:YAG, 70 microns for the Argon, and 45 microns for the CO2 laser. This study shows that demineralization is reduced significantly in vitro when human enamel is exposed to Argon and CO2 laser irradiation.
    Effect of a new carbon dioxide laser and fluoride on occlusal caries progression in dental enamel
    Nobre dos Santos, Marines, Univ. Estadual de Campinas; Fried, Daniel, Rapozo-Hilo, Marcia L., Featherstone, John D., Univ. of California/San Francisco
    Publication: Proc. SPIE Vol. 4610, p. 132-139, Lasers in Dentistry VIII, Peter Rechmann; Daniel Fried; Thomas Hennig; Eds.
    Publication Date: 6/2002


    Abstract:
    The purpose of this study was to investigate the effect of a new TEA carbon dioxide (CO2) laser (.9.6 micrometers , 5-8 microsecond(s) pulse duration) combined with fluoride (F), on the inhibition of caries-like progression in occlusal surfaces in sound and demineralized enamel. Of 120 occlusal tooth surfaces (10 per group), 90 were partially demineralized in a 50% HAP/0.1 M Lactic acid/carbopol solution (pH 5.0). Samples were treated with/without the laser (2.0 j/cm2 or 3.0 J/cm2) and/or F (as APF). Caries-like progression was tested by 5 days of pH cycling. Results were assessed by cross-sectional quantitative microradiography. The percent inhibition of caries progression with laser and/or F ranged from 87-170%. This new TEA CO2 laser produced significant protective effect against lesion progression, and in combination with fluoride treatment lesion reversal occurred.

    Hello to All,
    I discovered this site with the help of Mark Calonna while visiting his office for “training” which due to licensure only allowed observation.  While very invaluable (Thanks again to Mark), it was unnerving that this in the only clinical training that I could find.

    I had expected as Bob was talking about some hands-on training at a university, a manufacturer’s clinic, or a for-profit group of educators.  They abound for other aspects of dentistry: esthetics, C & B, materials, etc.

    I will, it seems, do pig jaws and as much reading that I can just to get comfortable with the modality and the feel for distances, pace (thank God for TIG welding school) and clinical judgement for application.  For that I will learn with my patients how much is enough or too much. I feel like I am starting my practice all over again with so much to work out: application, patient presentation, techniques, staff training, maintenance, supplies, etc.

    This Forum discussion and photos have already been helpful as has the suggested reading from ADL.

    This is nervous anticipation of delivery of the Waterlase and just wanted to say,” I’m in”. Hope the water is fine.

    Lee: I want to congratulate you for coming to this site. I think its great that users of different lasers come here to share information and to help eachother learn.

    There are many experienced users at this forum like Bob Gregg whose knowledge makes me feel like he has forgotten more than I will ever know.

    Yet , slowly and surely your knowledge will increase.

    In a big huge compliment to Ron, I have witnessed a massive leap in his knowledge from when he got his lasers to now. He has tried to read and listened to all and with this in mind his learning curve has been shortened substantially.

    Ron , thanks for putting the board together, 66 members already, I never thought I would see that day.

    Hi folks: As I sit at home recuperating over the flu and pneumonia , I started going through some of the thousands of pics I have shot through the scope and since there are so many new members here I thought I would share some of the tips I have uncovered for the laser over the next couple of weeks.

    WHen doing kids class 2s in deciduous teeth the beauty of the laser is that it wont cut metal like AA does so you can put a metal matrix on prior to prepping the teeth.

    This does 3 things…….

    1. It protects the adjacent tooth surface.
    2. It helps speed up the prep as there is reflection of the band, I am sure this is the case.
    3. If properly placed it can give you the original height of the marginal ridge.

    I have done this with T-bands and with Ultradents ultraguard. The ultraguard is a little thicker and sometimes I have to remove it and put in a tband to get a tighter contact but it is more rigid and able to get through broad wide contacts.

    Here are two cases for you to look at…………

    http://www.sendpix.com/albums/021208/133349000008c14cf94e20189a6d4f/

    The first case has an ultraguard and the second has two Tbands.

    Hi everyone,
    I had the incredible PLEASURE to meet Lee last week, as he spent a couple of days in my office. I have never met a more personable, professional man, dedicated to our profession. That is why I referred him to this site. He will do awesome things with the laser, in time. He reads, researches, just plain does his homework. He knew so much BEFORE he came to the office. I can’t wait to see what he does when he finally uses his laser. Now, that being said, I still agree with everyone else with education, and training. Dental Schools need this technology. It really needs to get into the didactical and clinical areas, and research as well. WE are doing the research right now, and that isn’t too fair. I just hope that those of us who are users will continue to teach each other, and share our knowlege here, and in other ways to improve and move this technology forward. That’s my 2 cents for now…I am sure I will have more to say at a later time as I need to get to work. Good day to everyone!

    HI all! It’s great to see this site growing! I agree with Mark, much of the research going on in this field is from us. However, I do sincerely want to thank Bob and Del for allowing some of us to follow your tracks in some of the phenomenal procedures. I also find, that the ideas generated by laser technology, as well as the fellowship with top quality docs across the country has made me much more creative ( out of the box thinking) as well as a much better dentist ( and I feel that I am continuing to improve all the time). For that, in the past, present and future, I want to say thanks to all who travel here for I know, you are a different kind of person just to be here in the first place.

    With that said, I hope each of you will take the time to share your experiences, techniques etc. here so that we may all learn from each other, and make this an even better site!

    Good Day and God Bless to All!

    Lee,
    Welcome to the board. Can’t wait til you get that laser going ,as I know how much more fun it has made dentistry for me.

    Thanks to all for their participation- that’s what makes the board so worthwhile. I know you all have helped me a ton!

    Todd,
    I was wondering if you could give some background on MALD and the process in obtaining it. I know you need to have standard proficiency, laser 2 years, present cases, but what kind of timetable for the cases?After 2 years or as you go along?When does a mentor become involved? Any advice?
    Thanks

    Excellent Glenn, Hope you are feeling better soon.
    Great tips, I will try them. Deciduous teeth are so easy to prep, and on top of that, the children are so cooperative. They never feel anything, and usually have zero anticipation of anything starting to hurt, unlike adults, who are just WAITING for some pain! Great stuff, as usual!

    Hey guys, Just one other thing to help reduce sensitivity with the Waterlase, Glenn, I am not sure with the Continuum unit, maybe you can help here. When I was in Phoenix, we were talking anesthesia with the laser, and I remembered to let everyone know that you can warm up the water in a waterbath before attaching to the unit for use. This makes it a bit more comfortable, especially for us in these colder climates. We turn our heat down a bit at night, so the standing distilled water cools down with the room. When we warm it, the patients definitely notice it when using it warm, that it’s more comfortable for them. It would be nice to have a inline water heater, BUT there is already so much in the lasers guts, that the waterbath seems to work real well. (And it’s free!). 😉 Just a tip that I hope helps those who use the Waterlase. Glenn, what type of water connection is in the laser you use?

    Dental Applications of Advanced Lasers
    by Jeff Manni

    The reference book costs around &#3685

    Learn without bias or hype about the full range of applications of dental laser technology.

    http://www.jgma-inc.com/

    Phone:  781-272-6692

    I have no &#36&#36 interest in the book.  I do hope to keep Jeff interested in updating his reference book, as it is the most useful, single source of any I have ever read about dental lasers.  I have purchased 4 of his editions since 1990.

    Enjoy!
