“…Nevertheless, there was no statistically significant difference for both groups. This result is in line with the research conducted by Yusri et al (2016), who showed that sodium ascorbate 10% combined with Tween 80 0.2% has the lowest coronal microleakage after intra-coronal bleaching using 35% hydrogen peroxide and requires a minimum application time of 48 h before composite restorations [50]. Regardless of the peroxide residue, several studies have shown that short application times (2-10 min) for antioxidants can increase bond strength in restored teeth after bleaching, indicating that the short application of antioxidants can reduce free radicals that affect bleaching on dentin bonding [37,51,52].…”

The present study aimed to determine the effectiveness of Trigona spp. propolis as an antioxidant to reduce residual peroxide after intra-coronal bleaching treatments. Thirty-five maxillary central incisors were divided into seven groups: five samples without antioxidants; sodium ascorbate 10% combined with Tween 80 0.2%; and Trigona spp. propolis 10%. The lengths of the application time were 1 h, 24 h, and 48 h. Each application time consisted of five samples. Root resection followed by artificial discoloration was performed in the samples. Then, intra-coronal bleaching using 35% hydrogen peroxide was applied. After the tooth color changed, the bleaching material was cleared, and this was followed by the applications of sodium ascorbate 10% combined with Tween 80 0.2% and Trigona spp. propolis 10%. The peroxide residue was measured by assessing dissolved oxygen using a titration analysis with either the Winkler or iodometric method. Data were analyzed using the ANOVA test and Tukey’s HSD test. The lowest peroxide residue amount was found with the application of antioxidants for 48 h after the intra-coronal bleaching treatment using 35% hydrogen peroxide. However, there was no significant difference between sodium ascorbate 10% combined with Tween 80 0.2% and Trigona spp. propolis 10% to reduce peroxide residues after the intra-coronal bleaching treatment (p > 0.05). Therefore, these findings indicate that Trigona spp. propolis 10% effectively reduces peroxide residues after intra-coronal bleaching treatments, which can interfere with the bond of the composite to the tooth surface and shorten the wait time for composite restorations after bleaching treatments.

Micro-morphological and organic-inorganic changes of dental structure as well as the effect of hydrogen peroxide on polymerisation of composite materials cause lower adhesion, i.e. poor bond quality between composite material and bleached tooth. The aim of this study was to determine the effect of different concentrations of carbamide (16%, 20% and 30%) and 35% hydrogen peroxide on bond strength of the composite materials and bleached endodontically treated teeth. Methods: The current study included 40 extracted human endodontically treated teeth. Internal bleaching was done using the “Walking bleach technique” method. The teeth were bleached with 16%, 20%, 30% carbamide or 35% hidrogen peroxide. After internal teeth bleaching, a class V cavity was prepared and restored with Tetric EvoCeram nanocomposite material. Microleakage was determined using dye method (silver nitrate) and measured on the incisal and gingival walls using stereoloupes. Results: The smallest dye penetration on the occlusal wall was found of teeth bleached with 20% carbamide peroxide (5,45 μm), and the largest dye penetration was on teeth bleached with 30% carbamide peroxide (7,25 μm). The smallest dye penetration on the gingival wall was found on teeth bleached with 16% carbamide peroxide (12,25 μm) and the largest dye penetration was on teeth bleached with 30% carbamide peroxide (20,00 μm). The difference was statistically significant (p 0.05). Conclusion: Microleakage was detected in all teeth restored with composite and bleached with the internal bleaching technique with 16%, 20%, 30% carbamide or 35% hydrogen peroxide.

“…1 Commonly used dental bleaching materials include hydrogen peroxide and carbamide peroxide. 2,3 Carbamide peroxide is more commonly used in home bleaching procedures than is hydrogen peroxide because carbamide peroxides are safer to use and cause fewer side effects. Carbamide peroxide is a combination of hydrogen peroxide and urea.…”

Objective: Carbamide peroxide 10% is commonly used in home bleaching procedure. Effectiveness of carbamide peroxide bleaching process as a home bleaching has no successor yet, but its use is still being debated due to the effects on oral cavity. Strawberries are one of natural ingredients that currently used to whiten decolorized teeth because it contains ellagic acid and malic acid. On contrary, malic acid is said to be involved in the process of erosion. The aim of this study was to compare tooth enamel hardness after application of dental bleaching agent carbamide peroxide 10% and strawberry gel.Material and Methods: Sample consists of 30 maxillary incisors were divided into 3 groups. The first group as control soaked in aquades. The second treatment group were applied with carbamide peroxide 10% and a third group applied with strawberry gel. Before and after the sample application, tests were performed to determine the hardness of tooth enamel as measured using Universal Hardness Tester.Results: Based on Friedman test, p-value = 0,000 (p <0,05; significant). This means that there was a significant difference in tooth enamel surface hardness of each group and treatment group using bleaching carbamide peroxide 10% and strawberry gel.Conclusion: There was a decrease on tooth enamel hardness after application of carbamide peroxide 10% compared strawberry gel.
