“…Tooth discoloration is usually treated with restorative procedures or using more conservative approaches such as tooth bleaching approaches (1,2). The tooth bleaching techniques performed either in office or by patients at home are carried out using bleaching agents based on hydrogen or carbamide peroxides (3)(4)(5).…”

The aim of the present study was to evaluate the effect of prior microabrasion on the teeth color change and tooth bleaching effectiveness. Eight sound molars were mesiodistally sectioned and the halves were randomly allocated to receive enamel microabrasion or non-abrasion (control) in one of surfaces (buccal or lingual), while the remaining surface received the other treatment. The tooth color on baseline was evaluated by spectrophotometer (CieL*a*b system). After the microabrasion procedure, the tooth color was measured again. Following, the specimens were bleached with 35% hydrogen peroxide for two sessions with one-week interval. The color was re-evaluated 7 days after each section and 30 days after the second session. The effect of enamel microabrasion on color changes was evaluated by paired T-test. Deltas L*, a*, b*, and E were calculated and data submitted to 2-way repeated measure ANOVA followed by Tukey`s test. Paired T-test was also used to assess possible differences on the ultimate color achieved after tooth bleaching. Enamel microabrasion reduced the lightness and increased the redness of specimens. Specimens that received microabrasion presented higher values of ∆L* than control after each bleaching procedure; and higher ∆a* after the 2 nd bleaching session. However, the prior enamel microabrasion did not affect the ultimate values of color parameters. Despite enamel microabrasion have modified the tooth color, this procedure did not affect the ultimate results achieved with tooth bleaching using a high-concentrated hydrogen peroxide.

“…Most studies on tooth bleaching only evaluate tooth sensitivity or color changes [3,6], but the patients' perceptions of their dental esthetics are of great importance for the design of clinical protocols [3,15,16]. In this study, we evaluated the effect of in-office tooth bleaching on patients' perceptions of their own dentofacial esthetics, as well as their opinion about smile.…”

“…Tooth bleaching is a noninvasive technique for treating tooth discolorations and presents a high success rate in obtaining the desirable tooth color [6]. The bleaching effect is achieved due to free radicals generated by the breakdown of peroxide, which degrade the organic structure of dentin, promoting its lightening [7].…”

<div class="WordSection1">Objective: This study evaluated changes in the esthetic perceptions of patients subjected to in-office tooth bleaching. Material and Methods: Fifty participants included in a clinical trial evaluating the in-office tooth bleaching answered two questionnaires about their dental esthetic perceptions. The participants answered the Orofacial Esthetic Scale (OES) questionnaire and the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) before and after treatment. The average scores observed at baseline were compared with those recorded after tooth bleaching using the paired t-test or the Wilcoxon signed rank test (α = 0.05). Results: Improvement in tooth color (reduction of 5.1 shade guide units) had a positive impact on patients’ perceptions. According to PIDAQ, tooth bleaching significantly increased the psychological impact and dental self-confidence; and reduced esthetic concerns. The OES demonstrated improvements in participants’ satisfaction for all questions, except for the one on “facial appearance”. However, higher effect size was observed for the question related to tooth color, as expected. Conclusion: Tooth bleaching was associated with an overall improvement in dental esthetic perception, even when only tooth color was affected.KeywordsPatient-reported outcomes; Randomized Controlled Clinical Trials; Tooth Bleaching.</div>

“…A estética é um conceito pessoal, cercado de subjetividade, o que explica a sua variação e a dificuldade de mensurar os seus resultados em uma população 7 . O escurecimento das estruturas dentais, principalmente quando acomete os dentes anteriores, pode causar um impacto negativo na imagem e confiança do paciente e por conseguinte, na sua qualidade de vida 8 .…”
