摘要

A large variety of in-offce bleaching agents are available in the market, causing confusion among the clinicians about selecting themost effective bleaching agent. The aim of the present study is to assess whether the composition, concentration and therapeuticprotocols recommended by the manufacturers have any in?uence on the effectiveness of bleaching agents through an evaluationof 8 in-offce bleaching agents in a case series using split mouth design. In total, 4 patients of the same age (22 years) and teethcolour (A2) were selected as study participants and eight bleaching agents were randomised among them between March andJuly 2019. Overall, 3 bleaching sessions were performed and the colour obtained was recorded using a digital spectrophotometer(Vita Easy Shade). The colour variation (?E) and lightness variation (?L) were calculated based on the CIELab system parameters,which is an objective assessment and assigns numerical values for colour variations. Colour measurements were made beforeand after tooth bleaching sessions. ?E and ?L were calculated from the difference between the last assessment and the baseline.Colour measurements were performed on the central portions of the upper central incisors (11 and 21). No colour differences wereobserved between the hemi-arches of the same patient treated with different bleaching agents. The different bleaching gels did notin?uence the bleaching result. Thus we conclude that the bleaching effect seemed to be related to the active component (hydrogenperoxide) and was not in?uenced by the other components of the bleaching gels.
