“…Two layers of silane coupling agent (RelyX Ceramic Primer; 3M ESPE) were applied to ceramic discs using a microbrush (Cavibrush regular, FGM), and after 60 s, they were dried with compressed air for 30 s and a thin layer of adhesive Single Bond 2 (3M ESPE) was applied. 10,19 For each group, a standard volume of the RBLA, sufficient to cover the surface of the ceramic discs, was applied to the center, and two matrix strips were lightly pressed to extrude the luting agent and create a film thickness between 100 to 250 μm. 33,34,35 The ceramic discs were luted to resin composite discs with the different RBLAs tested.…”

“…the adhesive procedures that are controlled in part by ceramic surface treatment and the materials used for adhesive cementation, 5 including the resin-based luting agent (RBLA). 5,6 The influence of the shade 2,7,8 and color stability of light or dual-cured 9,10,11,12,13,14 RBLA on the final color of thin ceramic restorations has been widely studied. 15,16 Studies also have suggested that the inorganic filler content of RBLAs can influence their adequate penetration into the grooves produced by ceramic surface treatment, acting on quality and durability of the adhesive interface.…”

“…Since the color of thin CLV can be affected by several factors and achieving natural tooth-like restoration is still one of the greatest challenges for restorative dentistry, 8,10,27,28,29,30 this study evaluated the influence of low, intermediate, and high barium borosilicate inorganic filler content (55%, 65%, and 75% of mass fraction, respectively) of experimental resin luting agent on the translucency parameter (TP), color change (∆E 00 ), and CIEL*a*b* individual color coordinates of simulated CLVs. The hypotheses tested were that the higher inorganic filler content had a larger effect on the optical properties (∆E 00 and TP) of simulated CLV.…”

The influence of inorganic filler content of resin-based luting agents (RBLAs) on color change (ΔE00), CIEL*a*b* (individual color coordinates), and translucency parameters (TP) of simulated ceramic laminate veneer (CLV) was investigated. RBLAs with low, intermediate, and high inorganic filler content (55%, 65%, and 75% mass fractions, respectively) were prepared. Feldspar ceramic (Vitablocs Mark II) specimens (1.2 mm × 0.8 mm, A1C shade) were bonded to simulated composite resin substrates (1.6 mm × 1.2 mm, A2D shade) using three experimental and a commercial (RelyX Veneer) RBLA (translucent shade). The ΔE00 was calculated by CIEDE2000 color difference metric under three conditions (before, immediately after, and 24 h after luting). The TP was calculated using CIEL*a*b* color coordinates measured over white and black backgrounds. Surface morphology of the RBLAs was analyzed. One-way and two-way analyses of variance with a post-hoc Tukey's test were used respectively to calculate TP, CIEL*a*b* coordinates, and ΔE00 (α= 0.05). Overall, the tested RBLAs presented clinically visible ∆E00 values under the three conditions evaluated. For all RBLAs, higher ∆E00 values were observed between measurements obtained before and immediately after luting. Different inorganic filler content did not significantly increase the opacity of the ceramic-luting agents-resin composite set. The variation in inorganic filler content did not influence significantly the TP of simulated CLV; although all of the experimental RBLAs tested yielded ∆E00 above the perceptibility threshold. The L*, a*, and b* individual color coordinates were cementation-dependent.

“…13 Nonetheless, the optical properties and the influence of its shade on the final color of veneers have been scarcely investigated. 5,14 The answer for whether or not distinct shades of flowable resin composites used as luting agent would yield clinically visible color differences on porcelain veneers of different opacities is still unclear. In line with that, shade matching between adjacent teeth is also a challenge for clinicians.…”

“…Upon falling of light on the surface of filler particle larger than the wavelength of light, light diffuse occur as a result of its refraction and reflection infinitely on the surfaces of those particles. A similar phenomenon occurs as a result of the porosity of CAD/CAM materials (26,27) . The greater the refractive index difference between particle size and matrix of either materials, the greater the refraction and reflection of light, which leads to an opaque effect in CAD/CAM materials (28) , and that is why the more translucent material (Vita Enamic) didn't affect the intensity of the curing light as did the less translucent (29) (Lava Ultimate).…”

The purpose of this in vitro study was to evaluate the effect of two types of modified CAD/ CAM restorative material and its thickness, together with the type of resin luting cement, and its method of curing on color difference (∆E) and VHN as an indicator of the degree of polymerization of resin luting cement. Materials and methods:A total of 36 groups were used in this study (n=5) where, 32 Groups representing the each of the two different resin luting cement materials, under each of the two different modified CAD/CAM materials interface with four different materials thicknesses (0.5 mm, 0.7 mm, 0.9 mm and 1.2 mm) and polymerized with either conventional halogen or LED light curing system. Another four groups were prepared representing the control groups for each resin luting cement and light curing unit used. ∆E Measurement: Specimens in all groups was measured just after polymerization at the top of the specimens after removal of the ceramic face and Mylar strip to be compared with stored in dry boxes in darkened incubator at 37˚C for one week to be subjected to the color measurement again at the surface of the specimens. Micro Hardness Measurement : The resin luting cement specimens were subjected to micro-hardness tester (Wilson Ò Hardness Tester, Model Tukon 1102, Buehler, Lake Bluff, IL, USA). The data obtained from the means of ∆E and VHN test were subjected to analysis of variance (ANOVA) followed by Tukey's test at a 5% level of significance.Results: Four-Way ANOVA was used to test the four main effects namely, type of indirect esthetic restorative material and its thickness, together with the type of resin luting cement, and its method of curing the types of resin luting cement, the mode of curing. The first main effect (type of modified CAD/CAM material) had two levels namely, Lava Ultimate, and Vita Enamic. The second main effect (modified CAD/CAM material thickness) had four levels namely, 0.5 mm, 0.7 mm, 0.9 mm and 1.2 mm. The third main effect (type of resin luting cement) had two levels namely Vario Link Dual and Nexus 3 LC. The fourth main effect (type of light curing unit) had two levels namely QTH and LED. Conclusion:Within the limitation of this study, it could be concluded that, the thickness of the CAD/CAM material and the type of the resin luting cement had a higher effect on the ∆E and micro-hardness, hence the degree of maturation, of resin luting cement than did either the type of tested CAD/CAM materials or the curing units.
