“…Potential alternatives to the use of antioxidants for the reversal of the bond strength of bleached enamel include laser irradiation, since two recent in vitro studies have shown that the application of Er,Cr:YSGG laser after bleaching led to a similar recovery of bond strength produced by sodium ascorbate (110,111). Laboratory studies have also investigated the effect of using non‐thermal atmospheric plasma (112,113) as a pre‐treatment or an activation source during tooth bleaching gel exposure.…”

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.

“…Nesta revisão sistemática, 5 autores decidiram recriar o ambiente da cavidade oral imergindo as amostras em saliva artificial, submetendo-as a estresse termomecânico ou inserindo-as em uma incubadora [12,[14][15][16]18].…”

“…Geralmente, os dentes de origem animal estão imediatamente disponíveis, em vez disso, os dentes recém-extraídos de humanos têm disponibilidade limitada, por isso são normalmente armazenados em soluções diferentes durante o período de coleta para evitar a desidratação e o crescimento de microrganismos [23,24]. O timol é comumente usado como solução de armazenamento em estudos de adesão e apenas 4 autores o utilizaram [12,15,18,19]. A literatura demonstrou que compostos fenólicos como o timol inibem o processo de polimerização.…”

“…O uso de certos agentes (caseína fosfopeptídeo de cálcio amorfo, ascorbato de sódio, extrato de casca de mangostão, quercetina, vitamina C, chá verde e camomila) Em relação aos agentes adesivos e ao protocolo que os autores utilizaram foi avaliada uma heterogeneidade, pois apenas 6 autores utilizaram o mesmo sistema, portanto não é possível excluir se esse fator pode afetar o valor de resistência ao cisalhamento (RCS) [11,[14][15][16][17]19].…”

Nos tratamentos ortodônticos, o fator mais comum da descolagem dos braquetes ortodônticos é a força mastigatória contínua, mas outros fatores também podem estar relacionados, como os tratamentos clareadores. Esta revisão sistemática objetiva analisar a influência dos agentes clareadores nos valores de resistência ao cisalhamento (RCS) dos braquetes ortodônticos. Foi realizada busca nos bancos de dados PubMed, Scopus, Web of Science, Embase e Google Scholar com base na ferramenta PRISMA, na aplicação da estratégia PICO e dos critérios de inclusão e exclusão, sendo selecionados 11 artigos para análise e discussão. Tanto o peróxido de carbamida como o peróxido de hidrogênio afetam o valor de resistência ao cisalhamento (RCS), tendo, a maioria dos estudos, concordado com a necessidade de ampliar o tempo entre o clareamento dental e a colocação dos braquetes ortodônticos, para evitar a fratura da adesão dos braquetes. Embora existam diferentes variações de períodos de espera, os resultados desta revisão destacaram que um período de duas semanas foi o mais comum. Além disso, autores sugerem a utilização de produtos em pacientes onde não é possível atrasar a fase ortodôntica. Infere-se que o tipo de clareamento e sua concentração afetam negativamente o valor do RCS, mas existem outros fatores que podem desempenhar um papel adicional, como o tipo de braquete e o tipo de adesivo.

“…Recently, laser application using photodynamic therapy (PDT) has been extensively and effectively used in dentistry ( Al-Qahtani et al, 2018 , Alkhudhairy et al, 2018b , Alkhudhairy et al, 2018a ; , Alkhudhairy et al, 2019 ) Among lasers, Erbium yttrium scandium gallium garnet (Er:Y 3 Al 5 O 12 ) (Er,Cr:YSGG) laser (ECL) has gained admiration among orthodontists in enamel conditioning ( Almoammar, 2019 ) and bleached enamel reversal ( Khan et al, 2019 ) and the displayed results are convincing. Similarly, ECL has been used to repair zirconia and LDC and have unveiled encouraging outcomes ( Miranda et al, 2014 , Cho et al, 2012 ).…”

Aim To assess bond integrity and modes of failure of metallic brackets to lithium disilicate ceramics (LDC) conditioned with Er,Cr:YSGG laser (ECL). Material and methods Sixty LDC were arbitrarily allocated into six groups (n = 15) according to the type of ceramic surface conditioning treatment. Group 1 surface treated with silane (S) only, group 2 surface etched with hydrofluoric acid (HF)+ S, group 3 surface conditioned with HF+ ultrasonic bath (UB)+ S, group 4 sand blasting (SB) of glass ceramic surface with 50 µm Al 2 O 3 , group 5 surface conditioned with self-etch ceramic primer (SECP) and in group 6 surface treated with ECL + S. After conditioning, the specimens were positioned in a universal testing device for shear bond strength (SBS) testing. Adhesive Remnant Index (ARI) was used to determine sites of bond failure. Among experimental groups analysis of variance (ANOVA) and Tukey multiple comparison test was used at a significance level of (p < 0.05). Results The highest SBS values were observed in group 3 HF+ UB + S (18.21 ± 1.241) and the lowest SBS values were displayed group 1 surface treated with S only (5.21 ± 0.23). Specimens surface conditioned in group 2 with HF+ S (17.85 ± 1.25), group 3 HF+ UB + S (18.21 ± 1.241) and group 6 ECL + S (17.09 ± 1.114) unveiled comparable SBS values (p > 0.05). Conclusion LDC conditioned with ECL at (4.5 W and 30 Hz) has a potential to be used in clinical settings alternate to HF acid.
