Design outcomes

Primary

MeasureTime frame
To evaluate the belaching efficacy of participants undergoing in-office bleaching with 35% hydrogen peroxide in an attachable syringe with two different application tips (application brush vs. conventional tip) using the Vita Classical, Vita Bleachedguide (?SGU) and VitaEasyshade spectrophotometer (?Eab, ?E00 and ?WID).—

Secondary

MeasureTime frame
To evaluate the absolute risk and intensity of tooth sensitivity in participants undergoing in-office bleaching with 35% hydrogen peroxide in an attachable syringe with two different application tips (application brush vs. conventional tip).;o evaluate the absolute risk and intensity of gingival irriation in participants undergoing in-office bleaching with 35% hydrogen peroxide in an attachable syringe with two different application tips (application brush vs. conventional tip).—
