Abstract
Low-level laser treatment, also called 'Soft Laser Therapy' has been used for more than three decades in the health system. It was rst introduced by
Mester and his colleagues. In-vivo and in-vitro experiments have shown that low-level laser is capable of speeding up repair process and also
reduce post-operative pain. The application of low-level laser along with gingivectomy would result in improved clinical conditions and faster
repair. Low level laser application following coronally advanced ap may enhance treatment prognosis in cases of gingival recession. Low-level
laser would also be useful in pain reduction and wound healing in case of gingival grafting procedures. The differences in research results may be
attributed, bearing in mind that low-level laser radiation depends on various parameters such as wavelength used, power, energy density, radiation
duration, radiation model and the distance from the site under radiation. Hence, this review focuses on the mechanism of low level lasers, their
effects on various tissues and the applications in the eld of periodontology.
