“…The minimum bond strength of Multilink Speed is in agreement with the study conducted by Farrokh et al [ 33 ] and can be elucidated with the following reasons: (a) lower degree of cure and higher water solubility as compare to Multilink N; (b) inability to remove the smear layer completely; (c) absence of hybrid layer; (d) insufficient penetration of this cement into the dentinal tubules and collagen fibers because of high viscosity,[ 33 ] and (e) existence of low-molecular-weight oligomers that allows water to penetrate the junction of resin cement and tooth structure.

Aim: This study aims to evaluate and compare the shear bond strength (SBS) of three different resin cements - total etch and rinse, self-etch and self-adhesive resin cements, used to bond the lithium disilicate restorations to human dentin. Settings and Design: Comparative - Invitro study design. Materials and Methods: Forty-five lithium disilicate (IPS E.max) discs (4 mm in diameter and 3 mm thick) were fabricated and randomly divided into three groups ( n = 15). The occlusal surfaces of 45 extracted human maxillary premolars were ground flat. Fifteen specimens were luted, under a constant load, with each of the following resin cement: Variolink N (Group VN), Multilink N (Group MN), and Multilink Speed (Group MS). All cemented specimens were stored in distilled water for 1-week following which, they were tested under shear loading at a constant crosshead speed of 1 mm/min until fracture on a universal testing machine; the load at fracture was reported in megapascals (MPa) as the bond strength. Fractured specimens were also inspected by the scanning electron microscopy. Statistical analysis of the collected data was performed using one-way ANOVA test, post hoc Bonferroni test, and Chi-square test (α =0.05). Statistical Analysis Used: Oneway ANOVA test and post hoc Bonferroni test. Results: Mean SBS data of the groups in MPa were: Variolink N (Group VN): 14.19 ± 0.76; Multilink N (Group MN): 10.702 ± 0.75; and Multilink Speed (Group MS): 5.462 ± 0.66. Significant differences in SBS ( P < 0.001) of the three resin cement were found. Intergroup comparison revealed statistically significant differences in SBS between Groups VN and MN ( P < 0.001), Groups B and C ( P < 0.001), and Groups VN and MS ( P < 0.001). Chi-square test used to compare the distribution of mode of bond failure among the three groups delineated that the cohesive failure was significantly more among Group VN, whereas adhesive failure was significantly more among Group MN and MS. Conclusion: Total etch and rinse resin cement, i.e., Variolink N (Group VN) produced significantly higher bond strength of all-ceramics to dentin surfaces than did the self-etch and self-adhesive resin cements, i.e., Multilink N and Multilink Speed, respectively.

“…Com o objetivo de criar um selamento coronário imediatamente após a obturação do canal radicular, é recomendável a restauração estética com a maior brevidade possível, utilizando um sistema adesivo na câmara pulpar (WOLANEK, 2001;KORASLI, 2007). Uma vez que os resíduos do cimento endodôntico podem interferir negativamente sobre a resistência de união do sistema adesivo autocondicionante, o condicionamento ácido da dentina poderá exercer efeitos benéficos sobre a interface de adesão, uma vez que a resistência de união da estratégia condiciona-e-lava na dentina é superior ao proporciona pela estratégia autocondicionante (REIS, 2013;FARROKH, 2012).…”

Objetivo: Avaliar o a influência da remoção de resíduos de dois cimentos à base de resina epóxi (SPL, Sealer Plus ou S26, Sealer 26), com etanol a 95% (ETA) ou xilol (XIL), na interface de adesão entre o sistema adesivo universal (SBU, Scotchbond Universal), utilizado na estratégia condiciona-e-lava, e o substrato dentinário da coroa dental, por meio da avaliação da resistência de união (RU), avaliada pelo teste de microcisalhamento, e análise do padrão de falha adesiva. Materiais e métodos: A face vestibular de quarenta coroas de dentes bovinos ex vivo foram preparadas e dividas e quatro grupos (n=10), de acordo com a composição química do cimento endodôntico (SPL ou S26) e protocolo de remoção dos resíduos (ETA ou XIL): SPL+ETA, SPL+XIL, S26+ETA e S26+XIL. Imediatamente após a impregnação da dentina e remoção dos resíduos do cimento, de acordo com o protocolos selecionado, a superfície dentinária foi condicionada com ácido fosfórico a 27% e aplicado o adesivo universal (SBU). Em seguida, 4 corpos de prova de resina composta foram fixados no local e, 24h após, submetidos ao teste de microcisalhamento e análise do padrão de fratura. Os dados de resistência de união foram analisados pelo teste de ANOVA a 2 critérios. Resultados:S26+ETA e S26+XIL demonstraram menores valores de RU em relação a SPL+XIL e S26+XIL (P < 0,05). Não houve diferença entre SPL+ETA e S26+S26 ou SPL+XIL e S26+S26 (P > 0,05). Conclusão: O xilol é o protocolo mais favorável para a remoção de resíduos do cimento à base de resina epóxi, independentemente da composição química do material, sobre a interface de adesão com o adesivo universal (SBU), utilizado na estratégia condiciona-e-lava.

“…Studies have reported that self-etching adhesive systems exhibit lower bond strength values than etch-and-rinse strategies. [ 8 9 ] Furthermore, universal adhesive systems combine the advantages of these two etching strategies, which simplify and accelerate the adhesive application. [ 10 ] However, the behavior of universal adhesives to dentin impregnated with endodontic sealers is still uncertain.…”

Aims: This study evaluated the hybrid layer formation and bond strength of two adhesive systems, Scotchbond Universal (U) or Adper Scotchbond Multi Purpose (M), after cleaning protocols using ethanol (E) or xylol (X), to dentin impregnated with an epoxy-resin based endodontic sealer. Settings and Design: The study design was an Experimental in vitro study. Methodology: One hundred bovine dentin specimens were randomly allocated into five groups ( n = 10): Computed tomography (CT) (control): Only acid etching + M; E+U; X+U; E+M. After the specimen preparation, images were obtained using confocal laser scanning microscopy to evaluate the hybrid layer formation. For microshear bond strength test, the dentin specimens were included in polyvinyl chloride tubes and four resin composite cylinders were placed on the surface. The analysis was performed 24 h after storage. Statistical Analysis Used: For parametric and nonparametric data, analysis of variance followed by Tukey test and Kruskal–Wallis, followed by Dunn test were, respectively, used at a significance level of 5%. Results: Regarding hybrid layer formation, all experimental groups were similar to each other ( P > 0.05). However, CT showed higher hybrid layer formation than other groups ( P < 0.05), except in relation to X+M ( P > 0.05). Bond strength was statistically similar among all groups ( P > 0.05). Conclusions: Hybrid layer formation in dentin impregnated with epoxy resin-based sealer and submitted to different cleaning protocols was similar to the control group only for X+M. No differences were found among the experimental groups. Regarding the bond strength, no effect was observed for any group.
