“…In the present study, shade evaluations were performed objectively with a spectrophotometer which is considered more accurate than visual one 36 . Color differences were calculated using both ∆E ab *, that is the metric more used for evaluate color changes after tooth whitening 2,7,9,11,13,14 and ∆E 00 7,31,33 that shows a better correlation with visual perception than ∆E ab * 31,36 . Regardless of number of bleaching gel changes, it was observed a similar tendency for both color differences formulas (∆E ab * and ∆E 00 ).…”

“…Given the large amount of in‐office bleaching agents available on the market, which vary in terms of concentration, composition, pH and/or application techniques, it makes difficult for the clinician to choose a bleaching gel that provides an effective treatment, in a short chair time and that promotes low incidence of adverse effects. Within this context, tooth sensitivity (TS) is a side effect commonly reported by approximately 50%–93% of patients who performed in‐office bleaching 2,9,11‐15 . It occurs mainly in the first hours post‐treatment and decreases considerably 48 h after 8,10,12 .…”

“…Os métodos que envolvem polimento e remoção de camada da amostra podem causar alterações nos resultados que são obtidos com agentes desmineralizantes, tendo em vista que esse que as amostras sujeitas a esse tratamento ficaram mais suscetíveis à desmineralização. Rezende et al (2020) realizaram a aplicação de nitrato de potássio a 10% ou gel placebo na metade da arcada superior do paciente. O clareamento de consultório consistiu em 3 aplicações num intervalo de 15 minutos em duas sessões clínicas, que tiveram um intervalo de uma semana, utilizando peróxido de hidrogênio a 35%.…”

“…The bleaching agents act by a complex oxidation process with the release of reactive oxygen species, which penetrate through the enamel interprismatic spaces and reach the dentin, breaking organic molecules and producing lighter, smaller and lighter compounds (De Geus et al, 2016;Kutuk et al, 2018). Regardless of the technique and bleaching agent used, adverse effects have been reported, including: tooth sensitivity (Rezende et al, 2020;2021), changes in the surface morphology (Torres et al, 2019;Parreiras et al, 2020) and changes in the physical-chemical properties of dental hard tissues (Jurema et al, 2018;Kutuk et al, 2018;Martini et al, 2020).…”
