A very simplified version of laser mechanics, the laser produces a beam of light energy that is coherent and collimated. That means the light is all the same wavelength and it is focused into a fine beam.
The various lasers used in dentistry are usually identified by the resonating material such as Yag, diode, chromium, CO2 or Alexandrite. This material is what determines the wavelength of the laser.
Different wavelengths of light energy are absorbed by different substances. For example some wavelengths are absorbed by water and some wavelengths pass right through water. If a substance absorbs the laser energy it will immediately take on the energy of the laser, usually as heat. The rapid heating of the tissue is what causes the changes we see with a laser.
Each wavelength will effect the tissues in quite different ways. For example a diode laser is absorbed by dark colors such as hemoglobin. That makes it ideal for cutting soft tissue but it will have no effect on tooth structure.
It is possible to focus the laser energy into a very narrow band so that it effects the tissue practically on a cellular level.

Think about the human effort to make the chart, type the label, arrange the contents, file new bits when they arrive in the mail, write the notes, pull the charts every day and then re-file them. And of course there is the daily ritual of the lost chart, which no one can find only to have it turn up days later hiding in a stack on the doctor’s desk.
Paperless charts are not only possible, they are faster, better organized and even less expensive that old fashioned paper records. In order to prepare to meet the demands of the patient of the future; go digital.

Currently on the Dell site the server below is listed at less than $1500. As configured it is ideal for a typical dental office with RAID 1 dual 160GB SATA hard drives 1GB RAM and the newest dual core processors. The price also includes Microsoft small business server software.
I have seen many hardware proposals for dental offices with servers specked at $7,000 or more. You don’t need that. This $1500 server will run most dental offices very well.

PowerEdgeTM 840Ideal for: Businesses with up to 25 employees seeking an affordable all-purpose server with excellent performance and expandability to accommodate future growth.
