LLLT(Low Level Laser Therapy/ Photobiomodulation)
Low-level laser therapy (LLLT) is defined as laser treatment in which the energy output is low enough to produce nonthermal and biostimulatory effects. The mechanisms of the effect of LLLT causing laser analgesia are due to the stabilization of depolarising potential of nerve fibers or effects on the cellular and biochemical processes of the inflammatory responses. It is a new treatment modality and has the advantages of being painless with no side effects. LLLT has effectively used in pain during orthodontic therapy, acceleration of healing process in the wound, teeth desensitization, reduction of bacterial load in ulcerative conditions like aphthous ulcer, infections ,etc.
