Hi traderdan, The Dental Color Analyzer uses optical fiber spectroscopy to determine the exact shade of the original tooth. This helps dentists in the matching of restorative materials. Right now they use color charts which are basically little, fake teeth all lined up in a row. They hold these teeth up to your teeth to figure out what color porcelain to use for the new tooth, or partial replacement. From the dentists I've talked to at the various shows we've attended and over the phone, this procedure is highly inaccurate and can be very costly to the dentists when they have to do re-work. The two biggest complaints I've heard from dentists are that they either had trouble differentiating between the colors; apparently as you age this ability diminishes and also, (and I'm not being sexist), men have a harder time distinguishing between the subtle differences of color - a male dentist told me that he gets his hygenist to do the color matching). The other problem is that, under the fluorescent lights of an office the colors don't match up properly. Then, when the patient goes outside in natural light, all of a sudden everyone can tell that they've had a tooth replaced. The DCA, through white-light refraction, shoots a little flash of light and then transmits the color code to the screen of the machine. The dentists can choose which system they use with the flick of a switch (there a a couple different charts) and then send the information to the lab. The beauty of this is that the probe is so fine that the tooth can be tested in nine different areas. Teeth vary in color from top to bottom, left to right, so a very realistic tooth can be created. Most dentists I've talked to said that the ideal situation would be if the lab they deal with has a DCA. Then, before the replacement work is sent back it can be double-checked, and there is literally no room for error. This is also great for the company because by selling the machine to labs AND dentists, it increases the revenues tremendously. Another great thing about the machine is it's small enough to be portable in an office or lab, and it can hook up to a computer so that all the data can be charted. Anyway, I hope I answered your question. Sorry if I was a bit long-winded... If you want to see a picture of the DCA, there is one on the Wolf website at wolfindustries.com . Amanda 1-888-253-6657
