Design outcomes

Primary

MeasureTime frame
Expected outcome 1: It is expected to find that the use of a dentifrice for sensitive teeth does not reduce the incidence and intensity of sensitivity of in-office tooth whitening when compared to regular dentifrice. The sensitivity outcome will be measured with the aid of a 10 centimeter scale, with the left end corresponding to “absence of sensitivity” and the right end “severe sensitivity”, in which the individual will register with a vertical line the region corresponding to their sensitivity. and with an analog numerical scale with scores from 0 to 4, ranging from no sensitivity (0), mild sensitivity (1), moderate sensitivity (2), considerable sensitivity (3) and severe sensitivity (4).;Outcome found 1: It was observed that the use of a toothpaste for sensitive teeth did not reduce the incidence and intensity of sensitivity to in-office bleaching when compared to regular toothpaste.—

Secondary

MeasureTime frame
Expected outcome 2: It is expected to find that the use of a dentifrice for sensitive teeth will not alter the effectiveness of in-office tooth whitening when compared to regular dentifrice. The outcome will be measured subjectively with the Vita Classical and Vita 3D Master shade guide and objectively through the spectrophotometer.;Outcome found 2: It was observed that the use of a toothpaste for sensitive teeth showed a difference in the effectiveness of in-office whitening when compared to regular toothpaste.—
