Primary Outcome Measures

Name	Time	Method
The color difference between the initial condition and after bleaching (1 week and 1 month) will be assessed using the Vita Classical (visual) and Vita Bleachedguide color scales and also with the Vita Easyshade (instrumental) spectrophotometer.<br><br>Expected Outcome 1:<br>38% PH and 37% PC gels will produce similar whitening effectiveness when not sonically activated.;Outcome 1:<br>In both visual and color instrumental evaluation, the whitening effectiveness was found to be the same for both 37% carbamide peroxide and 38% hydrogen peroxide.;Expected Outcome 2:<br>The use of sonic activation will not change the effectiveness of whitening with 37% carbamide peroxide.;Outcome found 2:<br>In both visual and instrumental color evaluation, it was observed that the whitening effectiveness was higher in the control and experimental groups where the sonic activation was not used.
