“…The decrease in the b* parameter, which shows the chroma value on the yellow‐blue axis, indicates that this variable tends toward blue. As expected from the results of previous studies [20, 36, 39, 40], negative Δ b * values were obtained in all bleaching and remineralization regimens in the present study. The fact that none of the remineralization procedures made a significant difference on this parameter may explain its ineffectiveness on bleaching results.…”

“…Additionally, EDS data from a recent study investigating the effect of fluoride‐containing remineralization agents on enamel mineral content after bleaching under different salivation conditions revealed no difference in normal flow for Ca%, Na%, and Ca/P compared to the placebo group. This was explained as a result of the remineralization effect being related to the action of saliva and the acquired pellicle rather than the action of the dentifrice [39]. Considering the findings obtained from other studies, the time factor as well as the pH value and concentration of the bleaching agent may have been effective in producing the differences in the results.…”

“…Traditionally, either ΔE ab [11,16,20,36,37] or, more recently, ΔE 00 [38][39][40] formulas have been used in many studies for examining the effectiveness of different bleaching protocols. However, color change analyses do not provide information about the change in whiteness.…”

This study evaluated the effect of remineralization agents on bleaching efficiency, enamel mineral changes, and post-bleaching color stability. A total of 112 enameldentin blocks were prepared from bovine teeth. Following initial color measurements, separate treatment regimens were carried out as follows: negative control (no treatment); positive control (bleaching only); bleaching, then NaF; bleaching + NaF (mix); bleaching, then CPP-ACPF; bleaching + CPP-ACPF (mix); bleaching, then nHAP+F; bleaching + nHAP+F (mix). Color measurements were repeated after immersion in distilled water for 7 days, and again after staining with coffee solution for 14 days. The CIELAB-based whiteness index was used to evaluate bleaching efficiency, and the CIEDE2000 color difference formula for color stability. Chemical investigation was performed using scanning electron microscopy with energy dispersive spectroscopy and X-ray diffraction analyses. The experimental groups showed significant increases in whiteness compared to the negative control, and the staining after bleaching did not result in statistically significant differences between the groups. Energy dispersive spectroscopic analysis revealed that bleaching protocols had no impact on elemental levels as well as the ratio of Ca/P. The combined use of bleaching agents with remineralization agents did not affect bleaching effectiveness but also did not provide an additional contribution.

“…The dentin of non-irradiated teeth presented welldefined dentinal tubules and collagen fibers, but after radiation there was an increase in the morphological alterations after 30-and 60-Gy radiation doses (37). Our finding of the greater effect of higher irradiation dose can be explained by the strong irradiation effect, which can damage the inorganic and organic structure of hard dental tissue and can be seen from the study by Ferraz et al, who determined that low salivary flow, which in this case can be connected to irradiation in the head area, had less capacity for remineralization of bleached enamel compared to normal flow (47).…”

Introduction: The aim of this study was to evaluate the effects of radiation and tooth bleaching on the physical and morphological properties of enamel and dentin on permanent teeth.Materials and Methods: Eighty fresh, non-carious third molars were used in this study. Before cutting the crown in half, the teeth samples were randomly allocated to treatment and control groups by using a lottery method. The first group (n = 20) underwent standard radiation protocol (2 Gy/fraction/day, 5 days/week) with bleaching treatment afterward using 16% carbamide peroxide gel, the second group (n = 20) underwent standard radiation protocol with afterward bleaching treatment using 38% hydrogen peroxide, the third group (n = 20) underwent a short, one strong, experimental dose of 70 Gy with afterward bleaching treatment using 16% carbamide peroxide gel, and the fourth group (n = 20) underwent one strong, experimental dose of 70 Gy with afterward bleaching treatment using 38% hydrogen peroxide gel. Groups 5–8 (n = 20) served as control as they underwent only bleaching treatment. Vickers microhardness and surface roughness were performed before (initial) and after irradiation and before bleaching or after only bleaching. The effects of irradiation and bleaching on microhardness (or roughness) of enamel and dentin were analyzed in the repeated-measures ANOVA model.Results: Enamel microhardness after experimental single 70-Gy irradiation or after standard radiation protocol and bleaching with 16 or 38% gel was not statistically significant from microhardness in the control group (p > 0.05). There was a statistically significantly greater reduction in the average microhardness of enamel and dentin during bleaching with 38% gel compared to 16% for both radiation protocols (p < 0.001). After experimental 70-Gy irradiation and bleaching, a 16% statistically significant increase in surface roughness was found for enamel (p = 0.006) and dentin (p = 0.018), while this was not recorded for 38% gel. There was a statistically significantly greater increase in the average roughness of enamel and dentin during bleaching with 38% gel compared to 16% (p < 0.001) for both radiation protocols.Conclusions: Directly induced radiation leads to potential damage of hard dental tissues, which can be further damaged by additional bleaching. If teeth whitening is necessary after irradiation, it is suggested to use lower concentrations of whitening gels.
