“…The application of whitening gel increases the pressure through the intertubular oxygen molecules released from hydrogen peroxide [34][35][36]. These molecules can diffuse and accumulate on the enamel and dentin, occupying an intratubular space, which increases the pressure on pain receptors present in the pulp [9] and prevents intertubular fluid movement.…”

Objective: To compare the clinical effect of two desensitizing agents used before the application of a bleaching gel based on 35% hydrogen peroxide (HP). Material and Methods: 30 patients were selected, and two desensitizing agents with different mechanisms of action were applied: Fluorine Neutral 2% (FN), which acts by blocking dentinal canaliculi while Potassium Nitrate 5% with 2% Sodium Fluoride (PN/SF) that acts in nerve transmission and blockade. Desensitizers were used before the application of 35% HP. For whitening, three clinical sessions were performed, with an interval of seven days, with three applications of the bleaching gel for 15 minutes, totaling 45 minutes/session. Tooth sensitivity (TS) was assessed with the numerical analog scale, and a spectrophotometer was used to obtain the color variation (ΔE). ΔE were submitted to ANOVA and Tukey test (p<0.05), and TS data were submitted to a two-way ANOVA analysis. Results: For sensitivity experience, the Tukey test indicated differences between PN/SF and the placebo I, but there was no statistically significant difference between FN and the placebo II. The TS was lower when the desensitizing gel was used during the bleaching procedure compared to after treatment, regardless of the desensitizing agents. Conclusion: PN/SF before in-office tooth bleaching can reduce TS intensity, and the use of desensitizing gel before bleaching did not affect the bleaching efficacy.

“…Upon closer examination, 22 of these studies were excluded for the following reasons: in 8 studies, no pigments were used during or after the bleaching process [28][29][30][31][32][33][34][35], 5 studies lacked a control group [14,16,[36][37][38], in 4 studies, the color difference, luminosity or whiteness index was not calculated [4,[39][40][41], in 4 studies, the full text could not be retrieved [42][43][44][45], and 1 study was a review [23]. This process left 17 documents eligible for qualitative analysis: 5 clinical trials [46][47][48][49][50] and 12 in vitro studies [21,[51][52][53][54][55][56][57][58][59][60][61].…”

The aim of this investigation was to conduct a systematic review and meta-analysis to determine the necessity of a white diet during or following a bleaching procedure. This systematic review and meta-analysis followed the PRISMA guidelines meticulously. The research question was: Is a white diet necessary during and/or after a bleaching treatment? In vitro studies or clinical trials reporting the color change in bleached enamel after the use of a free-staining diet were considered for full-text review. For the analyses, a random-effects model was employed. Statistical significance was defined as a p-value < 0.05. A total of 17 documents were eligible for qualitative analysis: 5 clinical trials and 12 in vitro studies. Only data from the clinical trials were included in the meta-analysis. For at-home bleaching, differences in the color among the subjects were not statistically significant during the first (p = 0.64), second (p = 0.26) or third (p = 0.43) weeks of treatment. Also, the color difference one month after finishing the bleaching treatment were not statistically significant (p = 0.27). The color difference one month after finishing an in-office treatment showed that the restrictions on diet did not significantly improve the bleaching outcomes (p = 0.90). According to the findings of this review, dietary restrictions are not necessary during or after bleaching procedures.

Es un procedimiento poco invasivo pero que debe ser aplicado cuidadosamente para lograr los efectos positivos del mismo (Câmara et al, 2020;Monteiro et al, 2020;Moreira-Goncalves et al, 2022).

El blanqueamiento dental está considerado como pieza fundamental en el embellecimiento de los seres humanos, ya que permite la restauración de la “sonrisa perfecta”. Este proceso en sí, es poco invasivo y juega como un gran papel como aliado en la restauración satisfactoria de la sonrisa y autoestima del paciente. Es un procedimiento que debe ser aplicado cuidadosamente para lograr los efectos positivos del mismo. El fundamento de esta técnica es aclarar la tonalidad que han sufrido los dientes por diversos factores: extrinsecos, intrínsecos y decoloraciones internas. Durante el procedimiento, es usual el uso de peróxido de hidrógeno (H2O2) en concentraciones que van del 10 al 32 % en volumen o el peróxido de carbamida, un compuesto conformado por peróxido de hidrógeno y urea concentraciones del 10 al 22 %. El uso de peróxido de hidrógeno se lleva a cabo fundamentalmente en los consultorios, mientras que el uso del peróxido de carbamida es un procedimiento doméstico. A pesar de los excelentes resultados que se obtiene al usar ambos blanqueadores, su uso puede ocasionar erosiones dentales y sensibilidad dentaria. El primer caso, puede llevar a la adherencia de bacterias cariogénicas como el Strepctococus mutans responsable de caries. Los resultados obtenidos, demostraron que el peróxido de hidrógeno es un agente más agresivo que el peróxido de carbamida, lo cual origina mayor sensibilidad dentaria y un mayor control bacteriano; en cambio el peróxido de carbamida fue mejor blanqueador y originó menor sensibilidad dental.
