“…Additional analyses based on optical profilometry will include a quantitative evaluation of enamel’s surface roughness. Contrary to these findings, others [ 7 , 12 ] have shown that enamel surface properties were negatively impacted by bleaching protocols modulated by high-concentrated bleaching gels (either 30% or 40% HP), independently of their pH values (either acidic or neutral), using similar AFM techniques. Therefore, it could be assumed that the compositions tested have the potential to resolve mild-to-severe dental discolorations without negatively impacting the chemical arrangement or surface properties of treated enamel.…”

“…Even though several reports have demonstrated the bleaching efficacy of IPB [ 4 , 5 , 6 ], other studies have indicated that the utilization of these highly caustic bleaching agents may result in the occurrence of adverse effects (short- and long-term), including irreversible changes in enamel topography [ 7 ] and chemical make-up [ 8 , 9 , 10 ], decreased surface microhardness [ 11 ], increased surface roughness [ 12 ], diminished bond strength [ 13 ], and reduced fracture resistance [ 14 ]. From the clinical standpoint, the most prevalent adverse effect reported by patients and clinicians is mild to severe dentin hypersensitivity (DH) [ 4 , 15 , 16 ].…”

The present study reports on the development and testing of novel bleaching agents containing co-doped metaloxide nanoparticles (NP; 0%, 5%, 10% v/w) and hydrogen peroxide (HP, 0%, 6%, 15%, and 35%). Bovine blocks (n = 200, A = 36 mm2) were obtained and randomly distributed into experimental groups (n = 10/group). NPs were incorporated into gels before bleaching (3 sessions, 7 days apart, 30 min/session, irradiated with violet light-LT). Color changes (ΔE00, ΔWID), mineral content (CO32−, PO43−), and topography were assessed (spectrophotometer, ATR-FTIR, and AFM) before and after bleaching procedures (14 days). Metabolic status and three-dimensional components of non-disrupted Streptococcus mutans biofilms were investigated using a multimode reader and confocal microscopy. The results indicate that ΔE00 and ΔWID significantly increased with NPs’ concentrations and LT. The enamel’s mineral ratio was adversely impacted by HP, but alterations were less pronounced when using NP-containing gels. The enamel’s topography was not damaged by the bleaching protocols tested. The bioluminescence results show that bleaching protocols do not render latent antibacterial properties to enamel, and the confocal microscopy results demonstrate that the 3-dimensional distribution of the components was affected by the protocols. The proposed nanotechnology improved the bleaching efficacy of experimental materials independent of hydrogen peroxide or irradiation and did not adversely impact the enamel’s surface properties or its chemical content.

Purpose: To assess the impact of fluoridated dental products (Toothpaste, mouth rinse, and fluoride varnish) on bleached tooth enamel's surface roughness (SR) and surface morphology when used before, after, or before and after the tooth bleaching process. Methods: A total of (64) bovine permanent incisors were prepared and divided into two main groups: Group (A) was treated before and after the bleaching. Group (B) was treated after bleaching only. The bleaching process used an Opalescence boost of 40% hydrogen peroxide. Each main group was divided into (4) subgroups: (A1, B1) Control, (A2, B2) treated with FluorKIN mouthrinse, (A3, B3) treated with FluorKIN toothpaste, (A4, B4) treated with Proshield FV. A profilometer was used to evaluate surface roughness. Also, to assess the morphological changes in the enamel surface, another (14) teeth samples were viewed under the SEM. Results: There was a statistically significant increase in SR after bleaching and a decrease in SR after treatment, and there was no statistically significant difference between the group receiving bleaching only and the group receiving preventive protocol before bleaching, confirmed by SEM analysis. The slightest increase in surface roughness was found in the fluoride varnish group, followed by the FluorKIN toothpaste group, then the FluorKIN mouthrinse group. Conclusion: According to the surface roughness means results in the present study, Surface roughness increased very little in the fluoride varnish group, followed by the toothpaste group and mouthrinse group, respectively.

“…After the bleaching protocols were completed, the specimens were immersed in coffee prepared with 2 g of instant coffee powder (Nescafé Classic, Nestlé, Vevey, Switzerland) and 200 mL of boiling distilled water for 30 min per day for two weeks [ 15 ]. The solution was prepared freshly every day.…”

The Effect of In-Office Bleaching with Different Concentrations of Hydrogen Peroxide on Enamel Color, Roughness, and Color Stability

et al. 2023

The aim of this study is to evaluate the effectiveness of in-office bleaching in esthetic dentistry on the roughness and color stability of the enamel surface, using different concentrations of hydrogen peroxide (HP). Fifty human incisors were randomly divided into 5 groups (n = 10). No bleaching was performed in the control group. For these groups, concentrations of 40% HP with fluoride (F), 35% HP with calcium (Ca), 25% HP with nano-hydroxyapatite (nHA) and 18% HP with nHA were used for bleaching in the test groups. Surface roughness was assessed at baseline after bleaching occurred. Color measurements were first obtained at baseline, then after the first and second sessions of bleaching, and, finally, after the staining protocol. Scanning electron microscopy and atomic force microscopy were performed. Statistical analysis was conducted with a one-way ANOVA, followed by a post hoc Tukey’s test and a paired-samples t-test (p < 0.05). All the bleaching gels used exhibited a similar color change (p > 0.05). Bleaching gels containing 18% HP with nHA and that containing 35% HP with Ca caused less surface roughness of the enamel. Of these concentrations, 25% HP with nHA caused the most surface roughness and no significant difference was observed, compared with 40% HP with F. The highest coloration after bleaching was observed in 40% HP with F and 25% HP with nHA. The lowest coloration was obtained in 35% HP with Ca and 18% HP with nHA but no significant difference was observed between them and the control group. A concentration above 18% HP does not increase the bleaching effectiveness. The results show that 18% HP with nHA and 35% HP with Ca resulted in the least increase in enamel surface roughness when compared to high-concentrate HP; however, it also prevented recoloration after bleaching.
