    Well, I realized I didn’t even post to my own post….

    Both the Pulsemaster and the PerioLase are free-running pulsed Nd:YAG solid-state lasers and were designed by the same designer and engineer, Mike Yessik and Rick Thompson.  ADT purchased the rights to the Pulsemaster in 1994 when their OEM deal with Sunrise went sour, while Millennium Dental Technologies (a company I co-founded with Dr. Del McCarthy) worked with Rick and Mike in January of 2000 to design from scratch a pulsed Nd:YAG laser with 21st Century technologies and to our specifications and our input to the clinical needs of end-users–novice and expert alike.  As an aside–We formed MDT when we couldn’t get manufacturers interested enough in our findings regarding the importance of pulse duration or lasers for their importance in periodontal therapy (not hygiene curettage)–hence the name we coined “PerioLase” cuz no one else was obcessed about lasers for perio like we were.

    PulseMaster 600 IQ

    1.  Analog power supply, multiple analog capacitors, free-running pulsed Nd:YAG laser.
    2.  6.00 Watts;  20-200 mj per pulse energy;  10-200 Hz
    3.  10″W x 19″D x 29″ H
    4.  75 lbs.
    5.  Single 100 microsecond pulse duration
    6.  Power:  110-120 VAC, 50/60 Hz, 10 Amps
    7.  Touch pad
    8.  Pre-sets for power and repetition rate.

    PerioLase MVP-7

    1.  Digital power supply, single digital capacitor, free-running pulsed Nd:YAG laser.
    2.  6.00 Watts;  20-300mj per pulse energy;  10-100 Hz
    3.  11″ W x 16.5″ D x 24.5″ H (with Cart)
    4.  45 lbs.
    5.  “Multi Variable Pulse” (MVP)–7 user selectable pulse durations:  100, 150, 250, 350, 450, 550, 650 microseconds (for variable clinical needs both hard and soft tissue)
    6.  Power: (Digital power supply)110-120 VAC, 50/60 Hz, 10 Amps, Single phase;  200-240 VAC, 50 Hz, 2 Amps
    7.  Touch Screen
    8.  3 presets for each pulse duration (21 total)
    9.  Procedure driven menu selection
    10.  Printer (upper left of device face)
    11.  Internal Molectron Power Meter (below fiber port)
    12.  Cart with storage bin
    13.  Continuous Fluence display in Joules (of total energy used during procedure)

    Del and I realized in 1993-94 that another parameter beside wavelength, power and repetition rate was necessary to control bleeding without charring and the delayed healing that goes with it.  Varying the pulse duration to be “longer” than 100-150 usecs was the answer.  But long pulse is not good for hard tissue (selective caries removal, dentin etching, calcified canal opening, etc) like 100 usecs is……

    It’s the same with erbium.  We realized when using experimental erbiums in beginning in 1990-1997 (Kavo in Germany, then P-Optics in California) that another parameter besides wavelength, power, and repetition rate (Hz) was needed for RAPID and SMOOTH cutting of crown preps without injury to the pulp (the electro-mallet effect for those who did gold foils).

    You could accurately say that the PerioLase is the next generation of the Pulsemaster having been prototyped by the same designer and engineer….so we must think very highly of the Pulsemaster!

    After trying to reinvent the wheel with the Pulsemaster, I became a Periolase user.

    First, thanks to Bob and Del for being pioneers in the field. The difference in tissue response, effectiveness etc is undescribable.

    Much hype is out there on other wavelengths etc. Sound science should be the basis for making a decision for those sitting on the fence. Millennium is the only company that I know of who fully back their product, do the research and provide a standard protocol in order to get consistant results.

    Who else out there is putting their money where their mouth is with a 6 month full money back guarantee? Dispite this, I know of NO returns! That should speak for itself.

    If a practitioner cannot make money with this machine in his or her office (cause their is a lot of perio out there as well as a long list of other documented uses) he or she needs to find another profession .

    The best test beyond the clinical aspect which is extremely significant, is the verbal response from the patients themselves. I am still waiting for my first negative response.

    Thanks Bob and Del for making me a hero for my patients and giving me great joy in a profession I love. And thanks to the organizer of this fine forum for productive discussion of the technology available today!
