“…(16) Yenisey et al evaluated the effect of surface treatments on the bond strength between resin cement and zirconium oxide ceramic with different adhesions. (19) The cooking time may have affected the bond strength, and 30 μm of silicon veneer (Cojet) along with the silane coupling technique increase the bond strength between the resin cement and various ceramics cooked together with zirconium oxide.

ARTICLE INFOBackground and Aim: Due to the importance of the bond strength between zirconia core (ZC) and porcelain veneer (PV) as well as the paradox about the functionality of sandblasting on the solidity between those layers, this research aimed to evaluate the effect of sandblasting on the shear bond strength (SBS) between ZC and PV. Materials and Methods: After preparing 20 zirconia discs (7 mm × 3 mm) in this experimental study, they were randomly divided into two groups of case and control. In the case group, sandblasting with 120-μm aluminum oxide particles (Al2O3) was performed under 3.5-bar pressure at 10 mm distance from the zirconia surface for 15 seconds. Next, all the samples were cleaned with ultrasonic and 96% isopropyl alcohol for 3 minutes as well as steam cleaning for 10 seconds. Then, the samples were veneered with porcelain (3 mm × 5 mm). SBS was assessed using a universal testing machine. After data collection, the mean and standard deviation (SD) were calculated and analyzed using T-test. Results: The SBS between ZC and PV was 62.56±8.35 MPa in the case group (after sandblasting) and 94.62±7.69 MPa in the control group. The SBS showed a significant statistical difference between the two groups (P=0.001). Conclusion: The result of this research indicated that sandblasting reduces the SBS between ZC and PV. Considering the limitations and the methodology of the study, the hypothesis regarding the positive impact of sandblasting on SBS was not proven.

“…The methods generally used to achieve this outcome include the following: (i) expanding the surface area of the ceramic to enhance the bond strength with the tooth structure; (ii) hydrofluoric acid etching to create a stronger micro-mechanical interlock; and (iii) the use of silane primer to achieve chemical bond strength [3]. However, hydrofluoric acid etching cannot be performed on zirconia because it does not contain glass, and silane primer cannot provide sufficient bond strength by itself as no reaction occurs because of the lack of silica in zirconia means that no reaction occurs [4].…”

This study examined the effects of 3 mol % yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP) ceramic surface treatments on the tensile bond strength and surface characteristics of enamel. To measure the tensile bond strength, the 3Y-TZP and tooth specimens were manufactured in a mini-dumbbell shape and divided into four groups based on the type of 3Y-TZP surface treatment: polishing (P), 110 µm alumina sandblasting (S), 110 µm alumina sandblasting combined with selective infiltration etching (SS), and 110 µm alumina sandblasting combined with MDP (10-methacryloyloxydecyl dihydrogen phosphate)-containing silane primer (SP). After surface treatment, the surface roughness, wettability, and surface changes were examined, and the tensile bond strength was measured. The mean values (from lowest to highest) for tensile bond strength (MPa) were as follows: P, 8.94 ± 2.30; S, 21.33 ± 2.00; SS, 26.67 ± 4.76; and SP, 31.74 ± 2.66. Compared to the P group, the mean surface roughness was significantly increased, and the mean contact angle was significantly decreased, while wettability was increased in the other groups. Therefore, surface treatment with 110 µm alumina sandblasting and MDP-containing silane primer is suitable for clinical applications, as it considerably improves the bond strength between 3Y-TZP and enamel.

ObjectivesIn this study, we evaluated the influence of different radiant exposures provided by single-peak and polywave light-curing units (LCUs) on the degree of conversion (DC) and the mechanical properties of resin cements.Materials and MethodsSix experimental groups were established for each cement (RelyX ARC, 3M ESPE; LuxaCore Dual, Ivoclar Vivadent; Variolink, DMG), according to the different radiant exposures (5, 10, and 20 J/cm2) and two LCUs (single-peak and polywave). The specimens were made (7 mm in length × 2 mm in width × 1 mm in height) using silicone molds. After 24 hours of preparation, DC measurement was performed using Fourier transform infrared spectrometry. The same specimens were used for the evaluation of mechanical properties (flexural strength, FS; elastic modulus, E) by a three-point bending test. Data were assessed for normality, after which two-way analysis of variance (ANOVA) and post hoc Tukey's test were performed.ResultsNo properties of the Variolink cement were influenced by any of the considered experimental conditions. In the case of the RelyX ARC cement, DC was higher when polywave LCU was used; FS and E were not influenced by the conditions evaluated. The LuxaCore cement showed greater sensitivity to the different protocols.ConclusionsOn the basis of these results, both the spectrum of light emitted and the radiant exposure used could affect the properties of resin cements. However, the influence was material-dependent.
