“…Yet, its discoloration and softening effect to resin composite was reported in the dental literature. Green Tea containing mouthwash represents one of the products containing natural ingredients, which could be a competitor for CHX [ 45 ].Yet, its effect on microhardness and color was not assessed. Another category of mouthwashes which have been launched in the dental market are the bleaching group.…”

Background: Surface microhardness and color stability of dental restorative material should be sustained throughout its functional lifetime to maintain the esthetic quality of the restoration. However, the frequent application of mouthwash may affect their surface microhardness and color stability. The aim of this study was to evaluate the effects of different types of mouthwashes with different contents on surface microhardness and color stability of dental nanohybrid resin-based composite. Methods: Disc specimens of nanohybrid resin composite (Luna Nano-Hybrid Composite) were prepared according to manufacturing instructions; specimens were incubated for 24 h in three types of mouthwash (Chlorohexidine, Listerine Green Tea, and Colgate Optic White Whitening Mouthwash). Artificial saliva was used as a control group. Surface microhardness was evaluated using Vickers microhardness device. Color stability after and before immersion in the different mouthwashes was evaluated using extra-oral spectrophotometer; the values of color change (ΔE00) were subsequently calculated. Data were analyzed using one-way ANOVA and post hoc test (p ≤ 0.05). Results: There was no significant difference between microhardness of resin composite immersed in artificial saliva, CHX, and Green Tea mouthwashes (78.5, 78.4, and 73.5, respectively) (p ≥ 0.1), while the bleaching mouthwash led to the lowest microhardness of resin composite, with significant difference compared to the three previous immersion media (p = 0.002). Moreover, there were significant differences in the color changes (ΔE00) of resin composite exposed to the various immersion media (p = 0.0001). Conclusions: The bleaching mouthwash led to a significant reduction in nanohybrid resin composite’s microhardness compared to the chlorohexidine and Green Tea containing mouthwashes. The resin composite’s color change was accepted in bleaching mouthwash but unaccepted in chlorohexidine and Green Tea containing mouthwashes.

“…Green tea, which is a polyphenol like the PACs, was reported to not negatively influence the color of the dentin‐resin marginal area (109). Indeed, Bansal et al (91) showed that 10% GT was more efficient than 5% PAC and 10% SA to reestablish enamel bond strength.…”

This review compiles the literature on the antioxidants used after tooth bleaching with either low or high‐concentrated carbamide and hydrogen peroxide to recover the bond strength. Antioxidants used in bleached teeth are mainly natural and non‐enzymatic, except for catalase. Commonly, antioxidants are applied to remove any reactive oxygen species (ROS) residues left from bleaching gels, which adversely affect adhesive procedures, such as restorations or orthodontic brackets bonding. Even though sodium ascorbate, the most thoroughly investigated antioxidant, showed the most efficient bond strength recovery at 10% concentration, its performance depends on the type of solution and the application time. Natural extracts, such as proanthocyanidins and green tea, showed satisfactory results in the reversal of bond strength at 5% and 10% concentrations, respectively. Sodium ascorbyl phosphate, α‐tocopherol, and catalase exhibited promising results, but further research is required. The adhesive system type plays an important role in the outcome of enamel bond strength after the antioxidant application. The postponement of either restorations or orthodontic brackets cementation following bleaching procedures seems to be efficiently replaced by antioxidant application prior to bonding procedures. However, the efficacy of using an antioxidant to recover bond strength depends on its type and application time.

Composite is a tooth-colored filling material that can change color by extrinsic staining such as coffee, tea and cuko pempek. Abrasive toothpaste can reduce stains but increase surface roughness. This study aims to determine the effect of the type of toothpaste for brushing on the formation of stains caused by coffee, tea and cuko pempek. This research is a quasi-experimental with pre and post control group design. 39 composite discs with a diameter of 1 cm and a thickness of 5 mm were prepared and divided into several groups, 1 group of negative control without treatment, 3 groups of immersion. Each immersion group was divided into 4 brushing groups, namely without brushing, brushing without toothpaste, brushing with abrasive paste and brushing with non-abrasive paste. Pre and post treatment discs were photographed and color changes were assessed using the CIE L*a*b and E system. Friedman, Kruskall Wallis and Mann Whitney U non-parametric analysis test was used to compare color values and color differences within groups and between groups. Based on this study, it can be concluded that there were significant color changes before and after the soaking treatment with coffee, tea and cuko pempek. The color change in coffee was significantly greater than that of tea and cuko pempek. There was no significant difference in color change between tea and cuko pempek. Conclusion: Brushing with toothpaste Keywords: composite; coffee; tea; cuko pempek; CIE LAB
