KWT: Kruskal-Wallis test; WSR: Wilcoxon signed-rank test; NL: without laser pretreatment; L: with laser pretreatment. Statistically significant at value < 0.05. a, b, cDifferent letters denote statistically significant differences between groups using the Bonferroni adjustment for multiple pairwise comparisons.
