“…Thus, there is need to study alternative antioxidants that are able to completely reverse the reduction in bond strength of bleached enamel. For this reason, the present study evaluated GT as an alternative to SA and the results showed to be satisfactory, as reported when EGCG, the most active and abundant catechin in GT, was tested (14). EGCG applied for 10 min was able to overcome the compromised bonding strength.…”

This study evaluated the effect of green tea application time on the bond strength of enamel after enamel bleaching. Enamel samples were obtained from 80 third molars and randomly divided into 7 experimental groups (G1-G7) and 1 group without treatment (G8): G1, bleached with 10% carbamide peroxide (CP); G2, CP + 10% sodium ascorbate gel (SA) for 15 min; G3, CP + SA for 30 min; G4, CP + SA for 60 min; G5, CP + 10% green tea gel (GT) for 15 min; G6, CP + GT for 30 min; G7, CP + GT for 60 min. The CP was applied onto the enamel surface for 8 h for 14 days. The SA was applied in groups 2, 3 and 4, and the GT was applied in groups 5-8 according to the above described application times. Immediately after treatment, the specimens were bonded with Adper Single Bond 2 and Filtek Z350XT. The specimens were prepared to microtensile bond strength analysis. Fracture mode analysis was performed using a stereoscopic loupe. The data were statistically analyzed by two-way analysis of variance, the Tukey's and Dunnett's tests (=5%). The means (standard deviation) were: G1, 23.3 (3.2); G2, 25.2 (3.9); G3, 26.4 (5.4); G4, 30.2 (4.5); G5, 26.6 (3.4); G6, 22.0 (5.4); G7, 31.4 (3.3); G8, 31.4 (3.2). All groups had a high percentage of adhesive failures. In conclusion, the bond strength values were higher than the value in the bleached group only when the antioxidants were applied for 60 min.

“…Khamaverdi et al [26] tested the application for 10 min of EGCG, the most active and abundant catechin present in green tea, and found that this time was sufficient to increase the shear bond strength values of the enamel to the composite resin. In the present study, we used the green tea with 60 % catechins without standardization of the EGCG content.…”

“…Recent research concerns raise the attention on the effects of natural herbal extracts. Numerous studies have indicated the anticancer, antibacterial and antioxidant effects of different plant extracts [27][28][29]. In addition, herbal products are non-cytotoxic, easily accessible, with a long shelf life [30].…”

The effect of the color change of stained and then bleached composite resins blocks have been evaluated. 28 blocks, made from Admira fusion composite resin and divided in 3 groups, were included in the present study. They were stained in coffee for 3 days and then bleached with Opalescence gel (GO) and experimental bleaching gel based on green tea extract (GE). All color indices were measured in all situations (initially, after staining and after bleaching) with Vita Easy Shade spectrophotometer. It was used the CIE*L*a*b system for the color change parameters. The group bleached with Opalescence presented the most significant color changes. The bleaching effect of the experimental gel is lower that Opalescence bleaching gel.
