Effects of light-emitting diodes curing unit (LCU) irradiation on nitric oxide and prostaglandin E2 (PGE2) production of MDPC-23 cells and lipopolysaccharide (LPS) stimulated MDPC-23 cells. MDPC-23 cells were irradiated for 20 seconds using LCU and LPS was treated with 100 ng/ml. The values of nitric oxide (A) and PGE2 (B) were measured in the supernatants of the culture medium using the Griess reaction and a commercial enzyme-linked immunosorbent assay kit. Values are represented the mean±standard deviation of results obtained in three independent experiments. *p<0.05 and **p<0.01 compared with the control group.
