“…Several preventive methods have been suggested to overcome the clinical problems related to compromised bond strength after bleaching. Some of the proposed methods included removal of the superficial layer of enamel 14) , pretreatment of bleached enamel with alcohol 15) , or use of adhesives containing organic solvents 16) . However, a widely made suggestion is to delay the bonding procedure after bleaching since the reduction in composite resin bond strength to freshly bleached enamel has been shown to be temporary 17) .…”

The aim of this study was to compare the effects of antioxidant treatment and delayed bonding, following intra-coronal bleaching, on the shear bond strength (SBS) and bond failure site of brackets bonded to enamel. Eighty mandibular incisors were divided into four equal groups. After root canal filling, specimens in Group 1 were used as control and not bleached. For experimental groups 2 to 4, bleaching agent was placed into the rest of the cavity for a four-day period and this bleaching treatment was performed two times. In Group 2, specimens were bonded immediately after bleaching; in Group 3, specimens were bleached and then immersed in artificial saliva for 30 days before bonding; in Group 4, specimens were bleached, treated with an antioxidant agent, and then bonded. The SBS values of bonded brackets were measured in megapascal (MPa), while adhesive remnant index (ARI) scores were determined after the brackets failed. The SBS values of Group 1 (mean: 20.3±7.1 MPa) and Group 4 (mean: 18.2±6.1 MPa) were significantly higher (p>0.001) than those of Group 2 (mean: 4.9±3.2 MPa) and Group 3 (mean: 8.7±4.9 MPa). No significant differences in SBS were found between Groups 1 and 4, and between Groups 2 and 3.

“…This interferes in the bond strength of adhesive resin to dentin and, consequently, in the biological compatibility of the adhesive system and clinical longevity of the restoration. [11][12][13] Enamel bleaching immediately before bonding with adhesive systems damages the bond strength between the materials.…”

According it has been demonstrated that dental substrates can recover from mineral loss after 14 days from the last bleaching agent application, there is no scientific information about this effect on the dental substrate-adhesive restoration interface. SUMMARYPurpose: This study evaluated the effect of bleaching gel containing 10%, 15% and 20% carbamide peroxide (CP) on the bond strength of dental enamel or dentin and resin composite restorations.Methods: The buccal surfaces of 12 bovine tooth crowns were conditioned with 37% phosphoric acid, and the adhesive resin Single Bond 2 and the resin composite Filtek Z350 were used to perform the restorations. The blocks were sectioned to obtain bar specimens. Each specimen group (enamel-E, dentin-D) was divided into four subgroups (n=15): S-artificial saliva; 10-10% CP bleaching; 15-15% CP bleaching; 20-20% CP bleaching. CP was applied for six hours daily for two weeks. The specimens were submitted to the σ test in a universal testing machine. The data were analyzed by one-way ANOVA and the Tukey post-hoc test and a correlation analysis (r) was performed.Results: For Group E, the mean value (± standard-deviation) was 21.86 (± 6.03)a, 18.91 (± Conclusion: In the current study, the bond strength of the restoration to enamel and the restoration to dentin were influenced by the application of CP and was dependent on the CP concentration in the bleaching gel.

“…Similarly, removal of the superficial layer, pretreatment of bleached enamel with alcohol, and use of adhesives containing organic solvents have been also suggested to result in complete reversal of the reduced enamel bonds [16][17][18] . Recently used bonding agents can be divided in two groups by their surface conditioning method.…”
