“…Other stress factors during the post-treatment phase of cementation may alter the strength of bonding in vivo; these include wetness, temperature, and mechanical stress. Many in vitro factors may also alter the strength of bonding; these include wetness during storage of specimens in water 17) or artificial saliva 18) . Additionally, factors such as temperature during thermocycling 4) , mechanical stress from four bond tests (shear, tensile, microshear and microtensile) 1) , loading variables 1,19) may alter the bonding strength.…”

The purpose of this in vitro study was to compare the shear bond strength (SBS) of five different resin cements to human enamel and dentin under different storage conditions. Five resin cements and their dedicated systems were tested. Teeth were embedded, ground flat to expose enamel or dentin and polished with sandpaper. Adhesive systems were applied according to the manufacturers' instructions. V2A steel cylinders with were silicated, coated, and cemented onto the teeth. Specimens were stored at three different conditions and subsequently thermocycled. SBS was measured. Significant differences were observed between the tested resin cements depending on the tooth surface. Different storage conditions influenced the bond strength, independent of the tooth surface, in all test cements. The bond strength of all experimental materials to enamel is higher than that to dentin surfaces. Furthermore, the adhesiveness decreases after wetness (hydro-) and hydrothermal stress, regardless of the tooth surface.

“…Self-adhesive resin cements can be used to eliminate pretreatment of the tooth structure in order to simplify the adhesive technique and reduce technique sensitivity [16,18]. However, due to its high viscosity and low etching capacity, the bond strength of self-adhesive resin cements is lower than that of conventional resin cements and adhesive systems for direct resins [10,11,16,18].…”

Introduction: Despite advances in adhesive dentistry, lasting bonds between indirect restorations and dentin remain a challenge. Objective: Therefore, the aim of this study was to evaluate the effect of chlorhexidine on the bond strength of self-adhesive cements to dentin after storage for 24 h and 90 days. Material and methods: Forty-eight human third molars crowns were included in polyvinyl chloride matrices using acrylic resin and worn to expose a flat dentin area. The specimens were randomly distributed into 8 groups (n = 12) in accordance with the self-adhesive cement (Rely X U200 and Smart Cem 2), the dentin treatment (application or not of 2 % chlorhexidine digluconate solution for 1 min) and the storage period (24 h or 90 d). Two cylinders' cements (1.4 x 1 mm) were constructed on the dentin surfaces of each sample, stored in distilled water for 24 h or 90 days and submitted to a micro-shear test. Subsequently, a failure analysis was performed to classify the failure into adhesive, cohesive, and mixed. Data were subjected to ANOVA and Tukey (0.05) tests. Results: There was a statistically significant difference between the materials (Rely X U200 > Smart Cem 2 -p < 0.05) regardless of the surface treatment and the storage period. Conclusion: The chlorhexidine application did not affect the immediate or delayed bond strength values, regardless of the self-adhesive cement.

“…However, the composition of the luting cements can influence its degradation in an acidic environment 6,7 . The luting cements available can be classified as water-based and resin-based cements [8][9][10] . The most commonly used water-based luting agents are zinc phosphate and glass-ionomer cements 11 .…”

“…The most commonly used water-based luting agents are zinc phosphate and glass-ionomer cements 11 . The resin-based luting cements are the most commonly used materials for the cementation of indirect restorations 9,10 , and they offer advantages over water-based cements, such as the ability to adhere to multiple substrates, high strength and less disintegration in the oral environment 3,[10][11][12] .…”

ResumoIntrodução: Poucos estudos investigaram as propriedades de superfície de cimentos após desafio erosivo. Objetivo: Avaliar a rugosidade da superfície (Ra), dureza Vickers (VHN) e morfologia de superfície de 4 cimentos após desafio erosivo. Material e método: Vinte amostras de cada cimento foram preparadas (4×2mm) e divididas em grupo experimental (desafio erosivo) e controle (saliva artificial) (n=10): Rely X U200 (U200); Rely X ARC (ARC); Ketac Cem Easy Mix (Ketac) e Fosfato de Zinco (ZnP). O desafio erosivo foi realizado com quatro ciclos erosivos diárias (90s) em bebida à base de cola e 2h em saliva artificial durante 7 dias. As leituras de Ra e VHN foram realizadas antes e após erosão. A porcentagem de perda de dureza (%VHN) foi obtida depois da erosão. A morfologia de superfície foi analisada por microscopia eletrônica de varredura (MEV). Foram utilizados testes de ANOVA, Tukey e T-Student (α=0,05). Resultado: Após a erosão, foi observado aumento dos valores de Ra em todos os cimentos testados, e os grupos U200 e ZNP tiveram a maior %VHN. Após imersão em saliva, apenas os grupos U200 e ZnP tiveram aumento significativo nos valores de Ra e não houve diferenças significativas entre os grupos quanto à %VHN. A análise em MEV mostrou que os grupos Ketac e ZNP apresentaram superfícies rugosas e porosas, e o grupo U200 apresentou maior degradação da matriz comparado ao grupo ARC. Conclusão: O desafio erosivo com bebida a base de cola afetou as propriedades de superfície de todos os cimentos.Descritores: Erosão dentária; cimentos de resina; cimentos de ionômero de vidro; testes de dureza. AbstractIntroduction: Few studies investigated the surface properties of luting cements after erosive challenge. Objective: To evaluate the surface roughness (Ra), Vickers hardness (VHN) and morphology of 4 luting cements after erosive challenge. Material and method: Twenty specimens of each cement were prepared (4×2mm) and divided into experimental (erosive challenge) and control (artificial saliva) groups (n=10): Rely X U200 (U200); Rely X ARC (ARC); Ketac Cem Easy Mix (Ketac) and Zinc phosphate (ZnP). The erosive challenge was performed by four daily erosive cycles (90s) in a cola drink and 2 h in artificial saliva over 7 days. Ra and VHN readings were performed before and after erosion. The percentage of hardness loss (%VHN) was obtained after erosion. The surface morphology was analyzed by scanning electron microscopy (SEM). ANOVA, Tukey and Student-T tests were used (α=0.05). Result: After erosion, all luting cements had increase in Ra values and U200 and ZnP groups had the highest %VHN. After saliva immersion, only U200 and ZnP groups had significant increases in Ra values and there were no significant differences among the groups in %VHN. SEM analysis showed that Ketac and ZnP groups had rough and porous surfaces, and U200 group had higher resin matrix degradation than ARC group. Conclusion: Erosive challenge with a cola drink affected the surface properties of all luting cements.
