I have been using a diode laser since 1999. The most amazing factor in using it has been the incredible response of the patients. It just doesn’t hurt. And it heals completely in just a day or two.
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.
According to Dr. Clara Munera the High Tech Marketing Manager for Ivoclar the reason the diode is so gentle is that the energy is directed to the tissue practically on the cell level. There is very little inflammation, edema or cell damage. By comparison electrosurge energy is dispersed into adjacent tissues and results in much more trauma and post operative inflammation.
Lasers have many advantages over conventional modalities. Lasers will seal blood vessels, lymphatic vessels and nerve fibers. As a result there is less swelling, less scaring, little need for sutures, and post operative pain is decreased by 90%.
