Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The expected primary outcome is the intensity of tooth sensitivity. By means of the quantitative sensory method and the use of cold temperature transmitter on the tooth surface connected to a computer software. A variation of at least 5% was used in temperature changes before and after the use of the bleaching product.;The actually observed outcome was the intensity of tooth sensitivity (in degrees Celsius) recorded before, 7 days, 14 days and 21 days after the beginning of the bleaching treatments. The method used was the Quantitative Sensory Testing, which by means of a descending cold temperature transmitter positioned on the buccal surface of the tooth, provided accurate cold temperature detection by the patient. In the group bleached using 10% carbamide peroxide with potassium oxalate (desensitizing) it was observed an increase in the intensity of tooth sensitivity 7 days (16.69) 14 days (16.73) and 21 days (16.07) after the treatment, when compared with the initial values ??(11.44). In the group bleached using 10% carbamide peroxide without the addition of desensitizing, there was also an increase in the intensity of tooth sensitivity 7 days (15.77) 14 days (16.56) and 21 days (15.92) after the treatment, when compared to baseline (11.31). Thus, among the initial values ??of both groups and the values ??of times 7, 14 and 21 days there was no statistically significant difference (p <0.05), showing that the desensitizing product was not effective in reducing the intensity of tooth sensitivity. | — |
