“…Using the program G‐Power 3.1, a .2 beta error, and an alpha error of .05, a sample calculation of 25 patients per group was obtained. Considering the dropout rate reported in other published trials (5%), it was decided to increase the sample to 28 patients per group, in agreement with the Δ E of the color of recent studies of our group …”

“…Unfortunately, clinical trials that focused on the stability of color for in‐office bleaching gels are somewhat scarce, and there is a general notion that the greater the time of follow‐up, the greater the percentage of regression of color . However, there is no consensus according to the literature . Several factors could be responsible for this controversy.…”

Objectives This split‐mouth, double‐blind, randomized clinical trial evaluated the 1‐year bleaching efficacy produced by two hydrogen peroxide gels with different pHs. Materials and Methods Twenty‐eight patients were divided into two groups corresponding to two different products: Pola Office (pH = 2.0/SDI) and Pola Office Plus (pH = 7.0/SDI). The treatment was assessed during and after the bleaching procedure up to 12 months post‐treatment. The assessment consisted of two bleaching scales shade guide units (ΔSGU) and spectrophotometric device (ΔE, ΔE00, and Whiteness Index) of both maxillary quadrants. Results for ΔSGUs in both scales and ΔE00 and Whiteness Index were compared using Mann Whitney test and ΔE measurements through the t‐Student test for paired samples in each evaluation time. The color rebound (1‐ vs 12‐month postbleaching data) was evaluated with Wilcoxon test (alpha = .05). Results During the different times of evaluation, the color variation was similar for both products (P > .05), both for subjective (ΔSGUs) and objective assessments (ΔE, ΔE00, and Whiteness Index). Also, both products showed a slight rebound after 12‐month postbleaching (P > .05). Conclusions Concerning the stability of color, in‐office dental whitening with two hydrogen peroxide gels of different pHs produced similar results, with no significant of regression, for 12 months postwhitening. Clinical Significance Bleaching using a neutral (pH = 7.0) in‐office gel demonstrated similar stability and rebound effect than an acidic one (pH = 2.0).

“…By means of objective evaluation, the group whose bleaching is activated by the laser diode has a greater color change compared to the group whose bleaching is activated by LED or plasma arc . A protocol using a low concentration of hydrogen peroxide (6%) catalyzed by hybrid light (LED/Laser) showed effective and stable color changes even 1 year after therapy compared with a conventional high concentration peroxide control (35%) …”

Objective This systematic review investigated the effect of vital laser‐activated tooth bleaching regarding efficiency and postoperative sensitivity. The search for articles was conducted on Medline (PubMed) database. The following keywords were used: “Lasers” [Mesh] and “Tooth bleaching” [Mesh]. Using the Boolean operator “AND,” the following Boolean equation was formulated: (“Lasers” [MeSH] AND “Tooth bleaching” [MeSH]). Materials and Methods Inclusion criteria were as follow: clinical trials in English or French available in full text. Article search was limited to the ones published between 2007 and 2019. Results A total of 12 articles fulfilled the inclusion criteria. The quality assessment of trials included was undertaken independently as part of data extraction process. A JADAD score was attributed to each paper. Conclusion A marked color change was noted for patients undergoing light‐activated bleaching independently of the bleaching agent. Regarding sensitivity, the results of the various studies proved controversial. Clinical Significance Laser activation of the bleaching agent promotes the efficiency of the treatment but does not reduce postoperative sensitivity.
