1 Introduction Tooth bleaching has become increasingly relevant in daily dental practice due to the growing aesthetic demands from patients [1]. This trend reflects widespread dissatisfaction with tooth color [1, 2], often amplified by social media influences and their impact on self-esteem, where constant comparisons with others are common [3, 4]. Two well-established tooth bleaching techniques are frequently discussed in the literature: at-home and in-office treatments [5, 6].

1 Introduction Concern for aesthetics in general has also been reflected in the field of dentistry, as the quest for the perfect smile has increased the demand for tooth bleaching, making it one of the most requested procedures by patients seeking a whiter and more perfect smile [1]. Among the bleaching techniques, the in-office approach uses high concentrations of hydrogen peroxide, which allows for a shorter treatment time compared to at-home bleaching [2, 3].
