Photobiomodulation of human gingival fibroblasts with diode laser - A systematic review.

Low-level laser therapy (LLLT) is being extensively studied in the field of periodontics as a noninvasive technique to achieve better results after nonsurgical and surgical therapy. However, there is a lack of definitive guidelines for the use of LLLT to promote gingival and periodontal wound healing. The primary objective of this systematic review was to critically analyze the studies evaluating the effect of low-level diode laser on human gingival fibroblasts and to develop wavelength-specific guidelines for photobiomodulation of human gingival fibroblasts.
