35 patients in this group underwent the whitening procedure using the Dexamethasone acetate intervention. Dexamethasone acetate: The volunteers in the Dexamethasone acetate group (experimental group) received six capsules of dexamethasone 8 mg each to be administered orally, initially two days before the first bleaching query as follows: 8 mg (1 capsule) 9 am two days before the first clinical session whitening; 8 mg (1 capsule) the 9 am to 1 day before session whitening, 8 mg (1 capsule) to 9 am on the day of the first session of whitening.Clinical intervention: 1- Dry teeth and apply Gingival Barrier to both arches. 2- Light cure. 3- Firmly attach a mixing nozzle to the Pola Office+. 4- Apply a thin layer of gel to all teeth undergoing treatment. 5- Leave gel on for 8 minutes. 6- Suction it off. 7- Repeat steps 5-6 twice times. 8- After the last application, suction all the gel off, then wash and apply suction. 9- Remove Gingival Barrier. 10- A placebo gel will be applied w

35 patients in this group underwent the whitening procedure using the Potassium Nitrate intervention Potassium Nitrate: The volunteers in the Potassium Nitrate Group (Placebo group) received 6 placebo capsules, who contained the same components of de dexamethasone drug except the active ingredient (starch \[50%\], lactose monohydrate \[35%\], dibasic calcium phosphate \[14%\], and magnesium stearate \[1%\]).Clinical session:1- Dry teeth and apply Gingival Barrier to both arches. 2- Light cure. 3- Firmly attach a mixing nozzle to the Pola Office+. 4- Apply a thin layer of gel to all teeth undergoing treatment. 5- Leave gel on for 8 minutes. 6- Suction it off. 7- Repeat steps 5-6 twice times. 8- After the last application, suction all the gel off, then wash and apply suction. 9- Remove Gingival Barrier. 10- A desensitizing gel containing 6% potassium nitrate will be applied with a brush on the labial surface of the teeth whitened for 2 to 3 minutes .
