Low Level Laser or Photobiomodulation in Dentistry

The introduction of laser light as a source of amplified, stimulated emission of radiation, gave clinicians and researchers a chance and opportunity to obtain and use these high-powered light on biological tissues to create a new perspective for its application in healing and tissue regeneration. The use of laser light at power levels (specific wavelengths and power) have been documented to be capable of protein denaturation, water vaporisation and tissue ablation. The purpose of this article is to explain the mechanisms of action and to explore the uses of this group of lasers in general dental practice
