In order to determine the bleaching efficacy between different agents, 40% of the studies addressed this issue, 40% of the studies addressed the evaluation of the effect of bleaching agents on the erosion of the dental enamel surface as the main outcome, one study (10%) evaluated the impact of tooth whitening on the quality of life of individuals and another study (10%) evaluated the effect of dark drinks on the outcome of tooth whitening.
