Laser irradiation did not increase the proliferation or the differentiation of stem cells from normal and inflamed dental pulp

The irradiation with low-level InGaAlP red low-level laser (660 nm) in four different energy fluences (0.05, 0.30, 7 and 42 J/cm2) potentiated neither proliferation nor odonto-osteogenic differentiation of hDPSC isolated from patients with normal and inflamed pulps.
