PFDI, physical facial disability index; SFDI, social facial disability index; LLLTG; low-level laser therapy group; CG, control group; HILTG, high intensity laser therapy group; ns, not significant.

^* p < 0.001 = significant differences in intra-group evaluation according to baseline (before treatment) using Friedman analysis and post-hoc analysis with Bonferroni correction.

^** p < 0.05 = significant differences among the treatment groups using Mann-Whitney U test or Kruskal Wallis test.
