Assessment of healing following low-level laser irradiation after gingivectomy operations using a novel soft tissue healing index: A randomized, double-blind, split-mouth clinical pilot study

Lasers have become a part of modern dentistry since the past three decades. A wide-ranging assortment of lasers is being used in periodontology for both soft and hard tissue surgical procedures. Regardless of the frequent practice of using these well-known surgical lasers, there is another lesser familiar class of lasers called the low-level lasers. The main doctrine behind using low-level laser therapy (LLLT) is centered on the biostimulation, or the biomodulation effect, which relies on the dexterity of low-intensity laser energy when irradiated at a specific wavelength, is able to modify cellular activities (increase in cell metabolism and fibroblast and keratinocyte proliferation).
