Effect of LLLT on wound size 36 h after irradiation. Linear mean length with the confidence interval for each wounded area is presented. As for the 24-h time point results, there was no significant difference in the linear mean length between the control positive and the three lower energy density groups (p > 0.5). The linear mean length of the control positive and the cells irradiated with 0.1, 0.2, and 1.2 J/cm2 was significantly decreased compared to the two other groups (p < 0.03). There was also a significant difference noted in the linear mean of the control negative compared to the cells irradiated with 10 J/cm2 (p < 0.0001). a,b Values with different letters are significantly (P < 0.05) different
