“…Whereas studies show that aging can have a negative impact on the shear bond strength of conventional resin cements [20], the bond strength of the newly introduced self-adhesive resin cements after long-term aging has not been investigated yet. [21]. Good long-term bonding capacity, however, is desired for clinical long-term success.…”

OBJECTIVES: The aim of the study was to test whether or not the shear bond strengths of six self-adhesive resin cements to dentin and to glass-ceramic, 24h and long-term-aged, are similar to the one of a conventional resin cement. METHODS: Human molars (N=168, n=12 per group) and silicabased glass-ceramic specimens (N=168, n=12 per group) were embedded in acrylic resin and randomly divided into 28 groups. The following resin cements were luted according to the manufacturers' instructions: Clearfil SA (CSA), G-Cem (GCM), SmartCem2 (SMC), SpeedCEM (SPC), RelyX Unicem (RXU), RelyX Unicem2 (RXU2) and Panavia21 (control group, PAN). Shear bond strength was measured initially (24h of water storage 37°C) and after aging (24,000 thermal cycles, 5/55°C). The failure types (adhesive, and cohesive) were evaluated after debonding. The shear bond strength values were analyzed using three-way and one-way ANOVA, followed by a post hoc Scheffé and two-sample Student's t-tests. RESULTS: RXU, RXU2 and GCM showed similar after 24h and aged shear bond strength to dentin as the control group. CSA, SMC and SPC exhibited significantly lower values. Before aging, none of the bond strength values to glass-ceramic differed significantly from the other. After thermocycling, GCM showed higher results to glass-ceramic than CSA, SMC, RXU2 and the control group. Analyzing failure types after spontaneous debonding and shear bond test at dentin, solely adhesive failures were found, while at glass-ceramic only cohesive failures occurred. CONCLUSION: Not all self-adhesive resin cements can be a valid alternative to conventional resin cements in order to bond silica-based glass-ceramics to human dentin.

“…Shear stress is considered the ideal representative of typical clinical stress. 9 Clinically, all-ceramic restorations are subjected to masticatory force under dry and wet conditions, and therefore, these conditions were considered in this in vitro study. Viotti et al 10 evaluated the bond strength of different self-adhesive cements and compared them with conventional luting cements and found that the bond strength of multistep luting cements was significantly higher than those observed with most of the self-adhesive cements.…”

“…11 The success in the bonding of conventional resin cement to teeth and ceramic depends on the type of adhesive used (total etch or self-etch) and the quality of the dentin surface pretreatment. Liu et al, 9 in their studies, justified that selfadhesive cements are not able to completely demineralize/dissolve the smear layer of dentin and that they have significantly lower bond strength than conventional resin cements that require the dentin to be treated with total-etch or self-etch systems. 7 The low bond strength recorded for self--adhesive resin cement is probably related to the cement's limited ability to demineralize and infiltrate dentin substrate.…”

“…Various measures used to enhance bond strength of resin cement and silica-based ceramics are etching with hydrofluoric acid/or grit blasting, which provides micromechanical attachment and chemical bonding by a silane coupling agent. 9 Studies by Holderegger et al 11 have confirmed that the mode of application of the priming mixture is a key factor for receiving high bond strength with Multilink N which is why the mode of application of a priming agent is strongly influenced by the operator, and hence, these systems are judged as technique sensitive. However, in contrast to Multilink N, RelyX was least influenced by the operator, probably because it uses no priming system, thereby rendering it less technique sensitive.…”

Aim:The aim of this study is to compare the shear bond strengths of conventional resin cement and self-adhesive resin cement bonded to lithium disilicate. Materials and methods:A total of 40 extracted human molar teeth were mounted in self-cure acrylic resin. Teeth were prepared to obtain flat occlusal surface. About 40 lithium disilicate specimens of dimension-10 mm in diameter and thickness of 2 mm-were fabricated using lost wax technique. The samples were divided into four groups: Groups I, II, III, and IV (n = 10). The specimens were surface treated with Monobond S silane coupling agent. Self-etching primer and bonding agent were applied on the bonding surface of the teeth in groups I and III. The specimens were bonded to the primed teeth with the Multilink N resin cement and subjected to the universal testing machine. The specimens were light-cured. Specimens in groups II and IV were luted to teeth using self-adhesive cement RelyX U100. The same force was applied over the specimen as mentioned above. Excess cement was removed, and light curing was done. The specimens in groups III and IV were subjected to thermocycling for 10,000 cycles at temperatures altering between 5°C and 55°C. Results:The shear bond strengths of conventional resin cement and self-adhesive resin cement with lithium disilicate were tested before and after thermocycling. Department of Pediatric and Preventive Dentistry, Sri Sankara Dental College, Thiruvananthapuram, Kerala, India Corresponding Author: Anip K Roy, Department of Prosthodontics, Purvanchal Institute of Dental Sciences Gorakhpur, Uttar Pradesh, India, e-mail: royanip86@gmail.com thermocycling has no significant effect on the bond strengths of conventional or self-adhesive resin cement. However, from the study, it is seen that conventional resin cement had a higher shear bond strength value than the self-adhesive resin cement. Conclusion:There was a significant difference between the average shear bond strength values of conventional resin cement (Multilink N) and self-adhesive resin cement (RelyX U100) when bonded to lithium disilicate disks, and thermocycling had no significant effect on the bond strength of conventional or self-adhesive resin cements.Clinical significance: Among all-ceramic systems available, lithium disilicate materials have emerged as an excellent esthetic material for fabrication of anterior and posterior crowns and three-unit anterior fixed partial dentures because of their high translucency and improved optical properties. For successful clinical outcomes, the luting agent should have high bond strength not only to the ceramic surface, but also to the tooth surface.

Objective: The aim of this study was to compare the shear bond strength (SBS) of two resin cements bonded to four leucite-reinforced ceramics after one week and one year of aging. Material and methods: Forty ceramic blocks (4 mm wide, 14 mm length, and 2 mm thick) were used (1 week) and reused at the back side (1 year). The blocks were abraded with aluminum oxide (90 µm) and randomly divided into eight groups for each time. Two dual resin cements (RelyX ARC and RelyX U200 self-adhesive, 3M ESPE) were bonded to ceramics Creapress (CRE -Creation / Klema), Finesse All-Ceramic (FIN -Dentsply / Ceramco), IPS Empress Esthetic (IEE -Ivoclar Vivadent) and Vita PM9 (PM9-Vita). For each resin, time, and ceramic block, after applications of the 10% hydrofluoric acid (for 1 min) and silane, 3 Tygon cut tubes were positioned over each block and filled in with the resin cements (light-cured for 40 s). The tubing molds were removed to expose the bond specimens as cylinders (area=0.38 mm 2 ) stored in relative humidity at 24±2°C for one week and at 37±2°C for one year. All bonds were tested in an Instron in shear (applied of the base cylinder with a thin wire -0.25 mm) at speed of 0.5 mm/min, until failure. Results: The Garcia et al. -Bond strength of resin cements to leucite-reinforced ceramics: part 2 -after one-year aging in water results were analyzed by ANOVA (resin cements, ceramic systems, and time) and Tukey test (p<0.05) for rank ordering of SBS. The FIN and IEE ceramics did not show significant SBS decreasing on aging with U200. The mean SBS decreasing for all the ceramics was 36% with ARC and 14% with U200 cement. Conclusion: The SBS of ARC cement were significantly lower for all ceramics with aging than that of U200 cement. The SBS of ARC cement was also weakened by aging. FIN ceramic + U200 cement proved to be the most stable and strongest bond strength, and PM9+ARC cement proved to be the weakest bond strength with low stability.
