Effect of low-level laser irradiation on osteoblast-like cells cultured on porous hydroxyapatite scaffolds.

What the authors concluded

Laser irradiation did not interfere in cell viability and proliferation as compared with the non-irradiated controls." "This study suggests that there is no effect of 915 nm laser irradiation at a dose of 2 J/cm2 on the proliferation rate of MG63 cells. Future investigations are needed to compare different dose and wavelength regimens in order to determine the optimal set of laser parameters for
