- Primary Outcome Measures
Name Time Method The absolute risk of tooth sensitivity (primary outcome) recorded at least once by the participant will be compared using the Mc Nemar test. The intensity of sensitivity will be compared using paired Wilcoxon statistical analysis
- Secondary Outcome Measures
Name Time Method The color change (secondary outcome) with data from subjective and objective color assessment will be compared between groups using the paired Wilcoxon test. For all tests, a significance level of 5% will be considered.
