“…There was a statistically significant difference between subgroup IIA (176.37 ± 42.38) and IIIA (249.42 ± 26.12). This result was similar to the study conducted by Shashibhushan et al 25 and Lokhande et al, 26 where they showed better shear bond strength using proanthocyanidin containing antioxidants. The possible reason could be due to the OPC groups having multiple donor sites on their outermost shell that trap hydroxyl free radicals, and those are removed by esterification of epicatechin by gallic acid, which enhances the free radicals’ scavenging ability.…”

A bstract Aim To evaluate the effect of antioxidants on the shear bond strength of composite resin to bleached enamel. Materials and methods A total of 120 extracted permanent anterior teeth were split into four major groups, one among them being a control group. Group I (bleaching + without antioxidant), group II (bleaching + 10% sodium ascorbate), group III (bleaching + 5% grape seed extract), and group IV (bleaching + 5% pine bark extract). All of the groups were bleached using a gel containing 35% carbamide peroxide, and then they were divided into two subgroups depending on when the bonding operation was to be completed—subgroup A was done in 24 hours, while subgroup B took 3 weeks. The universal testing machine was used to measure the shear bond strength. Results Subgroup IA showed poor shear bond strength than other groups, there was no statistically significant difference between subgroup IB, IIA, and IVA. Subgroup IIIA showed the highest shear bond strength than the remaining groups. Between subgroups IIA and IIB, IIIA and IIIB, and IVA and IVB there was no statistically significant difference. This shows that delaying the bonding procedure for 3 weeks shows similar shear bond strength when compared to groups that were immediately bonded after antioxidant applying groups. Conclusion All the antioxidants’ immediate application could reverse compromised bond strength. Among them, 5% grape seed extract shows the highest increase in shear bond strength.

O escurecimento dental pode ser interpretado como um ponto de tensão visual e a busca pelo clareamento dos elementos dentários são baseados na percepção individual e imersa sobre interferências culturais que o indivíduo sofre. Dentes claros e bem alinhados representam aspectos importantes para um sorriso considerado perfeito pelos padrões de estética facial e dental atualmente aceitos pela sociedade, sendo sinônimo de saúde e beleza. Foi desenvolvida uma pesquisa de revisão integrativa, desenvolvida mediante estratégia de busca nas bases de dados por meio dos DECs “clareamento total” e “carvão ativado”, em bases de dados como BVS e PubMed. Estabeleceu-se o critério de inclusão artigos publicados em inglês, português e espanhol, condizentes com discussões diretamente relevantes. Os critérios de exclusão foram artigos que não estavam dentro do período selecionado deste estudo, não foram selecionadas palavras-chave para filtrar as buscas e artigos de revisão. Uma das principais propagandas dos dentifrícios à base de carvão ativado é o seu potencial em clarear os dentes, sendo uma informação presente na maioria dos produtos comercializados e após a utilização desses dentifrícios, pode haver uma mudança de coloração dos dentes, dando uma aparência mais clara. Provavelmente, isto possa ser explicado pelo aumento do brilho e refletância do esmalte. Conclui-se, portanto, que há o carvão ativado possui efeitos maléficos ao paciente.

Objective This study aimed to evaluate and compare the impacts of the postbleaching application of sodium ascorbate, alpha‐tocopherol, and quercetin on the shear bond strength (SBS) of composite resin. Material and Methods 60 extracted intact maxillary first premolars were collected and were randomly divided into five experimental groups as follows (n=12): Group A (negative control): no bleaching, Group B (positive control): bleaching with 40% hydrogen peroxide (HP), Group C: HP±10% sodium ascorbate for 10min, Group D: HP±10% alpha‐tocopherol for 10min, and Group E: HP±1% quercetin for 10min. Composite bonding was done immediately after bleaching for Groups B‐E and without any treatment for Group A. After being stored in distilled water at room temperature for 24h, all specimens were tested for SBS in the universal testing machine. One‐way analysis of variance and Tukey's post‐hoc test were used to analyze the SBS values of all groups. Results The results showed that the bonding of composite to the unbleached group exhibited the highest mean value of SBS (22.68±2.91MPa). Among the antioxidant‐treated groups, the highest SBS value was detected in quercetin‐treated specimens (15.45±1.58MPa), which was significantly different from the positive control group (p<.05). Conclusion It could be concluded that 10% quercetin applied for 10min increased the bond strength to bleached enamel, but it was not able to reverse it completely.
