Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Data collection NEO-FFI data was collected in a Microsoft Excel data sheet and analyzed by a psychology that was blind to patient's expectations. According to the answers, each scale might get a score between 0 and 50.

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.
