Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The participants will be instructed to apply 20% carbamide peroxide bleaching agent (7 days—04 h each) (Opalescence® PF™, Ultradent Products Inc. USA—20% carbamide peroxide) , delivered by the bleaching custom tray.
followed by the application of tooth paste containing Bioactive glass 45S5 (Sensodyne Repair & Protect contains NovaMin® technology) delivered by the bleaching custom tray (7 days—30 min each).
The bleaching agent and 45S5 toothpaste will be delivered individually by the participants themselves at their home by the bleaching custom tray.
For monitor adherence to the intervention , the researcher will check the bleaching agent and toothpaste containers after 7 days of commencement of intervention to make sure that they are empty.
Intervention code [1] 318122 0
Treatment: Other
Comparator / control treatment
The participants in control group will be instructed to apply 20% carbamide peroxide bleaching agent (7 days—04 h each) delivered by the bleaching custom tray, followed by the application of non-active placebo paste, delivered by the bleaching custom tray (7 days—30 min each).
Both of the studied agents (placebo and Novamin) will have the same color and texture. in addition, they will be delivered to the patients by the same containers. this will be occurred in order to cover the blinding method of the study.

The composition of 500 g of the placebo tooth paste as follows:
Calcium Carbonate (Abrasive) 30% × 500 = 150 g
Sodium Lauryl Sulfate (Foaming Detergent) 2% × 500 = 10 g
Menthol oily (Cooling refreshing flavor) 1.2% × 500 = 6 g
Purified Water (Solvent) 30% × 500 = 150 g
Sodium Saccharin (Artificial Sweetener) 4% × 500 = 20 g
Cocaimdopropyl betaine (Foam booster – Thickener( 1% × 500 = 5 g
Sodium methyl cocoyl taurate (Foam booster – Thickener( 1% × 500 = 5 g
Glycerin (Humectant – Sweetener) 30% × 500 = 150 g
Carbopol (Thickener) 0.8% × 500 = 4g
Control group
Placebo

Outcomes
Primary outcome [1] 324485 0
Tooth sensitivity using visual analogue scale.
Timepoint [1] 324485 0
Follow-up will be daily for 7 days after application of both the bleaching agent and the Bioactive/placebo toothpaste. The primary outcome will be assessed by the patients themselves using visual analogue scale in the first day of commencement of intervention."
Secondary outcome [1] 384787 0
Color changes using digital spectrophotometer.
The digital spectrophotometer measures the shade of teeth based on the CIE L*a*b* color space system, allowing the determination of color in a three dimensional space
Timepoint [1] 384787 0
Baseline: before the beginning of the intervention.
Follow-up will be after 3 days , 1 week ,15 days, 1 month, 3 months and 6 months after intervention commencement of both the bleaching agent and the Bioactive/placebo toothpaste
