Secondary
| Measure | Time frame |
|---|---|
| Expected outcome: The color change between the initial condition and 14 days after tooth whitening will be analyzed using the Vitapan Classical Shade Guide (Vita Zahnfabrik, Bad Sackingen, Germany) and also with a digital spectrophotometer (Vita Easyshade Advance, Vita Zahnfabrik, Bad Sackingen, Germany).;Expected outcome: The degree of cooperation of the patients, using the tray with the whitening product, will be generated by the TheraMon micro sensor in both dental arches. The interpretation of the results obtained in each of the arcs will be carried out after the completion of the bleaching through the diagram of the time of daily use, in hours, of the trays with the whitening product; considering, therefore, the bleaching time proposed, that is, 2, 4 and 8 hours daily.;Expected outcome: The degree of satisfaction of the patient will be analyzed and measured 14 days after the completion of the bleaching process. To do so, the visual analog method will be used, through a scale of 0 to 10; the patients will be questioned about the degree of satisfaction observed with the dental bleaching performed, being stipulated the value 0 for the patients that did not present any satisfaction and 10 for those who presented the highest degree of satisfaction with the obtained bleaching.;Expected outcome: Dental sensitivity will be analyzed and measured for its presence and intensity 7 days prior to the initiation of the bleaching process, at baseline, after 7, 14 and 21 days after the onset of bleaching, as well as 14 days after the end of whitening. To do so, the visual analog method will be used, through a scale of 0 to 10; the patients will be questioned about the intensity of the discomfort caused by the treatment, being stipulated the value 0 for the patients who did not present any painful symptomatology and 10 when there was a severe sensitivity. 6 In the face of severe sensitivity, the patient will be excluded from the research. | — |
