The use of lasers in dentistry has increased considerably in the last few years. The LASER (Light Amplification by Stimulated Emission of Radiation) is characterized by different parameters but the ones important in medicine are power, wavelength and frequency. Depending on these characteristics, the laser could have a very beneficial effect on the living tissues by stimulating cell regeneration, increasing metabolism, stopping bleeding or eliminating pain. Most medical lasers are invisible (because their wavelength is outside the visible spectrum) and that is why they are equipped with a pilot light which is usually red.
In dentistry, we use lasers as non-bleeding scalpels, to detect and remove tooth caries (instead of noisy drills) and to promote tissue healing or accelerate implants’ osseo-integration. Using lasers is not yet taught in most dental schools curriculum as it is considered a specialty therapy, subject to master studies. Since the improper use could lead to irreversible damage, extensive additional training is required before a doctor is allowed to purchase and use a dental laser. In our practice, we use two type of lasers: diode 970nm, 7W laser (SIROLaser Advance) for soft tissue surgeries and cauterization, and a low energy laser for would healing and bio-stimulation (DioBeam 830 LLLT – Low Level Laser Therapy).
The major advantage of using lasers versus conventional scalpels is that the living tissue absorbs the light radiation. Depending on the wavelength and power, the laser light stimulates of the cells’ mitochondria (cells’ internal laboratory), more ATP is generated and the healing processes accelerate almost two-fold. Low level lasers are also called “cold lasers” because the transfer of energy is within the mili-Watt range and they are absolutely painless..
It is expected that lasers will become part of everyday dentistry. In the USA, many dental offices employ at least one type of laser while the more specialized dentists employ multiple types of lasers, which allows them to perform painless, quick-healing surgeries.
