Some parts of the published Legend of Fig. 4 should be corrected as follows.

Corrected Legend of Fig. 4

Figure 4. Effect of semiconductor diode laser irradiation on alkaline phosphatase (ALPase) activity in human periodontal ligament fibroblasts (PDLFs). All the laser-irradiated groups showed a significant increase compared to the control. ALPase activity of PDLFs was significantly greater at 3.94 J/cm2 of laser energy fluency compared to the others.

*Statistically significant from the control (P<0.05).

Statistically significant from the other laser-irradiated groups (P<0.05).
