Qualitative evaluation of osteogenic differentiation of SCAPs, The SCAPs were stained with 1% alizarin red to detect mineralized nodules, Density of ARS in the control (A, B), red LED (C, D), and LLL (E, F) groups after 24 and 48 h. A significant increase in osteogenic mineralization was observed in the LLL and red LED groups. Maximum increase was noted in the laser group. There was a smaller increase at 48 h than at 24 h
