“…Material was significantly related to both stress and elastic modulus. Regarding the pooled averages of σ interface for the three composites (Table 3), SDR generated the smallest stress, which was consistent with several studies 7,[28][29][30] . On the other hand, SDR was the stiffest composite, followed by Filtek and then Venus (Table 4).…”

The objective of this study was to investigate changes in polymerization stress and elastic modulus for light-cured bulk-fill resin composites following irradiation. Crack analysis was applied to obtain the stresses for 24 h after irradiation, which were calculated from the lengths of cracks in a glass mold bonded to the composites. The elastic modulus was repeatedly measured by nano-indentation tests performed over 24 h. The lengths of the cracks, the interfacial stress, and the elastic modulus were significantly affected by the material and time after irradiation (p<0.01). The stress and elastic modulus continued to increase for more than 6 and 1 h, respectively (p<0.05). Strong relationships (r>0.85) were revealed between the stress and elastic modulus. The bulk-fill resin composites generated smaller stresses than a flowable resin composite reported to generate relatively low stress. Post-irradiation polymerization during the first 1 h is a major determinant for the magnitude of stress.

“…Bulk‐fill RBC contains different types of filler and have different filler loading (Table ). While physical properties, such as the polymerization shrinkage and the depth of cure of bulk‐fill RBCs, have been extensively studied, the effect of tooth brushing these bulk‐fill RBCs has yet to be studied. Whitening dentifrices have become popular with both manufacturers and patients alike.…”

“…In addition, Bulk-Fill composites also have different photoinitiator systems, affecting the photocure degree. 13 Light-cured resins contain photoinitiators, which decompose after the visible blue light irradiation, releasing free radicals that activate the polymerization. 6 Two types of photoinitiators are used in Dentistry: type I and II.…”

Palavras-chave: Materiais Dentários. Polimerização.Resinas Compostas. Corantes. Descoloração de Dente. ResumoIntrodução: Recentemente, foram lançadas no mercado resinas compostas que apresentam baixa contração e baixa tensão de polimerização, as chamadas resinas compostas Bulk-Fill. Estas oferecem ao cirurgião-dentista a possibilidade de inserir incrementos de até 4 mm, tornando o procedimento restaurador mais rápido. Objetivo: relatar um caso clínico de restauração de um dente posterior com substrato escurecido utilizando uma resina composta Bulk-Fill de média viscosidade associada a um agente opacificador. Relato do caso: após exame clínico e radiográfico, um paciente do sexo masculino com 50 anos de idade foi informado sobre a necessidade de substituição de uma restauração de amálgama de prata insatisfatória na superfície oclusal do dente 16. A restauração foi removida e, em seguida, foi realizada a técnica adesiva para a restauração da cavidade utilizando-se um sistema adesivo autocondicionante de dois passos clínicos (AdheSE, Ivoclar Vivadent, Schann, Liechtenstein). Devido ao substrato dentinário escurecido, foi aplicado no fundo da cavidade um agente opacificador (IPS Empress Direct Opaque, Ivoclar Vivadent, Schann, Liechtenstein) e este, então, fotoativado por 40 s. A restauração foi executada com uma resina composta Bulk-Fill (Tetric N-Ceram Bulk-Fill IVB, Ivoclar Vivadent, Schann, Liechtenstein) em incremento único que foi fotoativado por 40 s. Acabamento e polimento foram realizados com auxílio de borrachas abrasivas. Resultado: ao final, obteve-se, com o auxílio do agente opacificador, uma restauração esteticamente satisfatória. Conclusão: é possível executar restaurações de maneira mais rápida com resina composta Bulk-Fill de média viscosidade. Entretanto, por se tratar de um material essencialmente translúcido, é recomendado o uso de um agente opacificador em dentes com substrato escurecido a fim de se obter um resultado esteticamente satisfatório. Abstract Introdution:Recently, composite resins that have low shrinkage and low polymerization stress have been released, the so-called Bulk-Fill composites. These offer the dental surgeon the possibility of inserting increments of up to 4 mm, making the restorative procedure faster. Objective: to report a clinical case of a posterior tooth restoration with discolored dentin substrate using a medium viscosity Bulk-Fill composite resin associated with an opacifying agent. Case report: upon clinical and radiographic examination, a 50-year-old male patient was informed about the need to replace the defective silver amalgam restoration on the occlusal surface of tooth 16. The unsatisfactory restoration was removed and then the bonding technique was performed to restore the cavity using a two-step self-etching adhesive (AdheSE, Ivoclar Vivadent, Schann, Liechtenstein). Due to the discolored dentin substrate, an opacifying agent (IPS Empress Direct Opaque, Ivoclar Vivadent, Schann, Liechtenstein) was applied to the bottom of the cavity, and then was photoactiv...
