- Outcome Measure
- Risk to the tooth sensitivity, The tooth sensitivity will be assessed using a Visual analogue (VAS) and verbal scales. VAS consisted of a 10-cm scale 0 (no sensitivity) 10 (unbearable sensitivity). A slightly air-stream will be applied over the buccal surfaces of the central incisors, and the patients will record their sensitivity perception by pointing with a pen on the scale. The distance between the marking and the border of scale, relative to the absence of sensitivity will be measured. The measurements will be scored according to the distance from 0, using a digital caliper. The tooth sensitivity will be evaluated using a 5-point Verbal rating scale (VRS), where 0 = none, 1 = mild, 2 = moderate, 3 = considerable and 4 = severe. Score different from 0 will determine presence of sensitivity. The risk of tooth sensitivity will be determined by relative risk assessed by ratio between absolute risk of experimental condition by those observed in control. The 95% confidence interval will be calculated., During the bleaching treatment.
