Statistical analysis For comparisons between scales between groups of patients were bleaching and who refused to be bleached Mann Whitney test was used.For each pair of scales it was determined if any one of them predominated over its counterpart by Wilcoxon rank test before and after bleaching . To corroborate the statistical power of this study was calculated post-hoc with the NEO-FFI scores values between the comparisons and showed a high statistical power (0.99) by G-Power software.
