However, after 14 days of illumination, the irradiation treatments did not increase ALP activity. The results of alizarin red staining showed that red LED promoted osteogenic differentiation of the PDLSCs. The real-time polymerase chain reaction (RT-PCR) results demonstrated that red LED upregulated the expression levels of osteogenic genes. Expression of the proteins BSP, OPN, OCN, and Runx2 in the irradiation groups was higher than that in the control group. Our results confirmed that low-energy red LED at 1, 3, and 5 J/cm2 pro
