“…The degree of whitening obtained in this study is similar to that reported in other clinical trials 9,17,19 and also in the literature review. 1 Finally, it should be mentioned that only a value-oriented shade g uide was used for identification of color changes throughout the study period. This was done because it is an easy, fast, and satisfactory method used in several investigations.…”

“…However, this bleaching protocol has a very high risk of tooth sensitivity, which may occasionally be severe. 1,2 Bleaching-induced tooth sensitivity has been associated with microscopic surface defects and sub-surface pores in the enamel, 3 with consequent reduction in enamel microhardness. 4,5 This is because of the low pH of the in-office bleaching gels available in the market.…”

Effectiveness of nano-calcium phosphate paste on sensitivity during and after bleaching: a randomized clinical trial

Abstract:The study aimed to evaluate the effectiveness of in-office bleaching and associated tooth sensitivity on application of nano-calcium phosphate paste as desensitizing agent. Bleaching was performed with 35% hydrogen peroxide gel in 40 patients who were randomly divided into placebo and nano-calcium phosphate paste groups. Bleaching efficacy (BE) was evaluated using a value-oriented Vita shade guide. Tooth sensitivity was recorded using a numeric rating scale (0-4) during bleaching and up to 48 h after each session. The primary outcome of absolute risk of tooth sensitivity was compared using the Fisher's exact test (α = 0.05). The intensity of tooth sensitivity and the efficacy of in-office bleaching were also statistically evaluated. No significant differences in absolute risk and intensity of tooth sensitivity were detected between the groups (p = 1.0 and p = 0.53, respectively). BE was also found to be similar between the groups (p = 0.67). Although the use of a nano-calcium phosphate paste associated with fluoride and potassium nitrate did not influence the whitening outcome, but it also did not reduce bleaching-induced tooth sensitivity.

“…This last change color was mainly related to increasing on lightness and reduction on yellowness, whereas the no significant modification on redness was observed. The measurement of color after 30 days was chosen to determine any residual effect of tooth bleaching and to simulate clinical conditions when a rebound effect has been demonstrated (3,24). The rebound effect tends to slight reduce the effect reached by tooth bleaching and is mainly due to physiological response to pulpal damage.…”

“…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 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).…”

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.

“…As a result, simpler molecules that diffuse out of the tooth or reflect less light are formed, creating a successful bleaching action. 2 The bleaching reaction depends upon the type of discoloration involved and the chemical and physical environment present at the time of action, that is, concentrations, 2,3 heating, 4 lightening, 5 pH, 6 co-catalysts, [7][8][9][10] times of application, 3 and other conditions. Most current office bleaching products employ high concentration H 2 O 2 to produce higher amounts of free radicals.…”

Objective: The objective of this study was to evaluate the effects of a 405 nm diode laser on bleaching reaction of H 2 O 2 and VL-TiO 2 on methylene blue (MB) dye. Background data: Visible light activating titanium dioxide photocatalyst (VL-TiO 2 ) may improve efficacy of hydrogen peroxide (H 2 O 2 ) bleaching agents used in dentistry while contributing to their safety by lowering the required concentration of peroxide. Methods: The experimental solution was prepared with H 2 O 2 , VL-TiO 2 , MB, and pure water. The final concentration of H 2 O 2 was 3.5% and that of MB was 10 ppm. The experimental solution of 3 mL in a quartz cell was irradiated by a 405 nm diode laser with various powers, duty cycles, and pulse durations for 7 min. Results: In all irradiation conditions, the increase in laser irradiation time gradually decreased the MB concentration. Irradiation by higher output power showed more reduction of MB concentration. Pulse durations as short as 5 ms with duty cycle reduced to 25% did not affect the degree of the reduction in MB concentration compared with continuous wave irradiation at the same average output power. Conclusions: It was concluded that using 405 nm diode laser, the bleaching effects of VL-TiO 2 depended upon the irradiation time and the average output power, regardless of pulse duration or duty cycle.
