“…31 It is expected that remineralizing treatments help to prevent light scattering by filling the porous areas and improve the appearance of enamel. The current results agreed with Mohammed et al, 34 who proved that CPP-ACFP showed the most significant color stability and staining resistance compared to Fluoride Varnish and CPP-ACP. CONCLUSIONS CPP-ACP, CPP-ACFP and nano hydroxyapatite improved surface roughness, surface microhardness, and surface irregularity of demineralized enamel surface particularly with nano hydroxyapatite.…”

Objective: This study aimed to evaluate the effect of CPP-ACP, CPP-ACPF and nano-hydroxyapatite on enamel remineralization during fixed Orthodontic treatment. The treated specimens with different remineralizing agents were compared with their untreated and demineralized ones regarding surface roughness, surface microhardness, and color measurement. Materials and methods: A total number of 120 specimens from extracted orthodontic patient teeth was collected and divided into 4 equal groups (10 specimens each) according to the enamel surface treatment applied immediately after PH cycling; group A received no surface treatment and served as a control group. In group B, the enamel surface was treated by CPP-ACP, while group C enamel surface was treated by CPP-ACFP, and group D was treated by Desensibilize NanoP. The surface roughness was obtained using surface Profilometer and Vickers microhardness was measured using Digital Display Vickers Microhardness Tester. Evaluation for each specimen was performed before, after pH cycling and after using different remineralizing agents. The color change was analyzed for each specimen in different groups under the Spectrophotometer. The change in color from control specimens compared to the color of the demineralized specimens (ΔE 1 ), the difference in color between control specimens and after remineralization (ΔE 2 ) and the change in color between demineralized and remineralized specimens (ΔE 3 ) were calculated. The results were then statistically analyzed and compared using ANOVA and LSD test at level of significance 0.05. Results: The use of CPP-ACP, CCP-ACFP and NanoP significantly improved surface roughness, surface microhardness especially with NanoP with non-significant difference between the three remineralizing materials. NanoP exhibited the lowest change in color compared with CPP-ACFP and CPP-ACP paste. Conclusion:The use of CPP-ACP, CPP-ACFP and NanoP could be used as preventive materials during orthodontic treatment and be effective in repairing the demineralized enamel restoring its surface smoothness, hardness, and color.

“…Various remineralizing products have been explored to mitigate the adverse effects of bleaching procedures. Fluoride, being the initial and widely used compound in post-bleaching treatment, gained popularity for its capacity to facilitate mineral deposition on enamel surfaces [25]. The current study's findings revealed significant differences in mean surface roughness among the four groups after treatment.…”

“…The findings demonstrated a significant increase in enamel surface remineralization after the application of whey extract over a 15-day period [25]. Another study in 2021 aimed to assess the remineralizing potential of whey extract, comparing it with commercially available minimal intervention (MI) varnish containing fluoride and Xylitol mouthwash.…”

Background: Extrinsic discoloration is treated with bleaching which increases enamel porosity and roughness. Remineralizing materials is applied to avoid the bleaching side effects. The current study aimed to evaluate time dependent safety of bleaching materials on enamel surfaces roughness, and to assess the remineralizing potential of whey extract as a natural product and to compare it with the commercially available fluoride varnish and fluoride mouthwash after maximum bleaching time (30 min.). Methods: Extracted human incisor teeth without cracks or any enamel defects were used in this study. Teeth were cleaned and decoronated at the level of the cementoenamel junction. A nail varnish was used to cover the entire surface of the crowns of each tooth, leaving a window measuring 4 mm × 4mm. Bleaching material was applied to the enamel of all teeth specimens. The Application of bleaching material was repeated 2 more times, each time for 10 minutes, which amounted in total to 30 min. The specimens in group 1 were soaked in artificial saliva, the specimens in group 2 were soaked in whey extract, the specimens in group 3 were treated with fluoride varnish and group 4 specimens were soaked in fluoride mouthwash. Results: The mean value of the surface roughness of all the teeth specimens was increased significantly after bleaching for 10 minutes, 20 minutes and 30 minutes (p=0.000) when compared with baseline mean value. As well, there was significant direct correlation between application time of bleaching material and mean value of surface roughness (r= 0.94). There were no significant differences (p>0.05) between the specimens of the 4 groups when the mean value of surface roughness compared at baseline and after bleaching. But, after treatment, there was significant difference (p≤0.05) between the 4 groups, with the best result obtained from whey extract and fluoride varnish. Conclusions: The enamel surface roughness is significantly and directly correlated with prolonged application time of bleaching material. Remineralizing materials; whey extract, fluoride varnish and fluoride mouth wash had significantly decreased enamel surface roughness caused by bleaching. Whey extract has statistically the same effect as fluoride varnish on decreasing the surface roughness of bleached enamel surface.

“…Four different remineralising agents were applied to the enamel surface after a bleaching agent containing 10% CP was applied, and the results were compared with a control group. The group without a remineralised adhesive produced the highest surface roughness values, and it was concluded that the increase in surface roughness also increased the susceptibility to recolouring [24].…”

Objective: This study aimed to evaluate the effect of experimental bleaching gels containing chitosan and theobromine compared with BioWhiten ProHome and FGM Whiteness Perfect bleaching gels on tooth surface roughness, microhardness, and colour change. Materials and methods: One hundred-forty-four upper central incisors were used for microhardness, surface roughness, and colour analysis (n=12). Before bleaching, surface roughness was measured using a profilometer, microhardness was analysed using a Vickers test, and colour was measured using a spectrophotometer. Group 1, an experimental gel containing chitosan-theobromine (16% CP); Group 2, an experimental gel containing chitosan-theobromine (6% HP); Group 3, BioWhiten ProHome (6% HP), and Group 4, FGM Whiteness Perfect (16% CP). Microhardness and surface roughness tests were performed under the same conditions before and after bleaching and 14 days after the bleaching. Colour analysis was performed before the bleaching, during the application, 24 hours after bleaching, and on days 7 and 14. p <0.05 was considered significant. Results: Although there was no statistically significant increase in microhardness values after bleaching in any group (p>0.05), effective bleaching was detected in all groups, and the highest efficacy was observed in Group 4 (p<0.05). Conclusions: The experimental gels containing theobromine and chitosan produced effective bleaching and did not have any negative effects on surface roughness or microhardness. Clinical Relevance: Bleaching agents lead to the formation of reactive oxygen species, which have genotoxic effects. Theobromine and chitosan can provide clinicians with positive results for bleaching, such as the ability to use lower HP concentrations and avoid side effects.
