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

also found that the differences between the test and control groups were highly significant at 24 h postirradiation but decreased in an energy-dependent manner at 48 and 72 h postirradiation, and hence, they suggested that repeated irradiation may be necessary in the clinical environment.[ 12 ] In the 900–1000 nm spectrum, only 940 nm diode laser has been evaluated for its efficacy to stimulate gingival fibroblasts.
