One of the basic purposes in dental treatment is providing a painless treatment for patients. This purpose may be achieved by the application of laser in dentistry. Low-level laser therapy (LLLT) is an internationally accepted title for biomodulation with low-level lasers which we use to achieve ideal therapeutic effects. Low-level laser therapy is a painless, reproducible, non-invasive, and without need of anesthesia treatment which is used to treat a variety of pain syndromes, injuries, wounds, fractures, neurological conditions and pathologies. Laser therapy works on the principle of inducing a biological response through energy transfer. The parameters that used in laser therapy determine the effective depth of penetration. We can mention anti-inflammatory effects, stimulation of wound healing, stimulation of immune system, increase of blood flow and activation of vasodilatation, increase of cellular metabolism and analgesic effects as advantages of the application of this type of laser. The aim of this review study was to evaluate the effect of low-level laser therapy after oral surgeries.
