- Primary Outcome Measures
Name Time Method color difference between the sides cleared the end of the study, verified by classical vita scale bleaching vita and the Spectrophotometer Easy Shade device, from finding a variation of at least three points in pre and post intervention analysis.
- Secondary Outcome Measures
Name Time Method sensitivity difference between the whitened sides, checked on a scale (NRS) and visual analogue scale (VAS), from finding a variation of two points on a scale and four-point visual analog scale in the analysis pre and post intervention.<br>Difference in cytokine levels in the gingival crevicular fluid (inflammation) after bleaching, through the concentration of inflammatory mediators (interleukins) in the analysis pre and post intervention .<br>Difference in the volume of gingival crevicular fluid after bleaching, checked by the amount of fluid present in the analysis pre and post intervention.
