Evaluation of Low-Level Laser Light Effects With a Wavelength of 660 nm and Different Amounts of Energy Density on Cell Proliferation by the MTT Assay. As it is evident in the figure, low-energy laser radiation significantly increased the viability of Hu02 cells in doses of 1 and 5 J/cm2 (P < 0.05) and had no impact on viability of the cells in 10 J/cm2 doses. The histograms are the mean of 3 independent experiments; error bars represent SEM.
