“…The bleaching effect is achieved due to oxidative action of peroxides and its sub-products on the organic matrix of the tooth tissues modifying its optical properties (6,7). Despite the high success rates observed for both in-office and athome bleaching procedures (4,5), using oxidative agents are unable to solve aesthetic alterations of teeth when the discoloration is intrinsic in the enamel due to fluorosis staining and other enamel hypoplasia, or white lesion spot caused by dental caries (8,9).…”

Impact of Microabrasion on the Effectiveness of Tooth Bleaching

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.

“…4,5 Tooth bleaching procedures are performed either in-office or at-home using high-and low-concentration peroxides (hydrogen or carbamide peroxide). 6 Regardless the protocol or bleaching used, the peroxides and their sub-products oxide the organic structure of tooth substrates resulting in lighter aspect. 7,8 Considering the higher organic content and chromaticity of dentin, it is reasonable to relate the bleaching effect mainly to optical modifications on this tissue.…”

Impact of 35% Hydrogen Peroxide on Color and Translucency Changes in Enamel and Dentin

This study evaluated the effects of tooth bleaching with high-concentration of hydrogen peroxide on alterations of translucency parameter (TP) and color of dentin and enamel. The crown of five human molars was sectioned into four slices parallel to buccal surface. The dentin of external slices containing buccal/ lingual enamel was fully removed with diamond bur; while these slices were used to assess alterations on enamel. Alterations on dentin were assessed into the center of internal slices. The color of specimens was measured over white and black backgrounds using a spectrophotometer (CieL*a*b) at baseline, allowing to calculate the TP by difference between the color measured over each background. Specimens were submitted to three 15-min applications of 35% hydrogen peroxide followed by their storage in water for one-week. Afterwards, the color measurements were repeated at both backgrounds. Color (∆L, ∆a, ∆b and ∆E) and translucency (∆TP) changes were calculated and data individually analyzed by T-test (α = 0.05). Influence of hard tissue and assessment time on each color parameter was also analyzed by 2-way repeated measure ANOVA (α = 0.05). Tooth bleaching resulted in increased lightness for the enamel, whereas no alteration on this parameter occurred for dentin. No difference between the tooth hard tissues was observed regards the other color parameters and ∆E. A slightly reduction on TP was observed only for the enamel. In conclusion, 35% hydrogen peroxide caused similar color and translucency changes on dentin and enamel.

“…Additionally, bleaching agents, including strips, paint-on, or hydrogen peroxide-filled trays, can be purchased over the counter [9]. Despite the similar results obtained by patients who used at-home and inoffice techniques [8,10,11], those performed in-office are widely preferred by patients who are not willing to use trays or who want to avoid any contraindication associated with at-home techniques, such as gastrointestinal disorders [12].…”

“…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]. Tooth bleaching can be achieved by using either at-home techniques -when the patient uses a hydrogen peroxide-filled tray at home, or in-office procedures, by applying high-concentration bleaching agents over the discolored teeth [8]. Additionally, bleaching agents, including strips, paint-on, or hydrogen peroxide-filled trays, can be purchased over the counter [9].…”

<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>
