RANKL, OPG, and ALP Gene Expression Levels 24 Hours After Nd:YAG Laser Irradiation.
cont: Control group not irradiated with the Nd: YAG laser.
0.6 W, 2.0 W: Experiment groups irradiated with the Nd: YAG laser at each output. **P < 0.01, * P < 0.05 vs. control; n=3.
The graphs show the fold-increase in the expression of the RANKL, OPG, and ALP genes 24 hours after Nd: YAG laser irradiation.
The expression of the RANKL, OPG, and ALP genes and the RANKL/OPG ratio 24 hours after irradiation were higher in the 2.0 W laser irradiation group than in the control group.
