“…However, a major challenge to aesthetic restorations is to provide optical behavior similar to natural teeth (2). The optical properties of a ceramic system depend on their translucency, opalescence, fluorescence, surface texture and shape, firing temperature, number of firing cycles, thickness, processing method and the used resin cement (3)(4)(5).…”

The purpose of this study was to evaluate color stability of two dental ceramics cemented with two resin cements, assessing the color difference (ΔE 00 ) by the measurement of L*, a*, b*, c* and h* of transmittance. The combination of two ceramic system (feldspathic and lithium disilicate) and two resin cements -color A3 (RelyX ARC and Variolink II) resulted in 4 groups (n=5). Ten disks-shaped specimens were fabricated for each ceramic system (10x1.5 mm), etched with hydrofluoric acid (10%) and silanized prior to cementation. The color analysis was performed 24 h after cementation of the samples and after 6 months of storage in relative humidity by means of spectrophotometry. The ΔE 00 values were analyzed statistically by two-way ANOVA followed by the Tukey test (p<0.05). One-way ANOVA were calculated for the means of individual color coordinates (L*, a*, b*, c* and h*). Two-way ANOVA showed that only the ceramic factor was significant (p=0.003), but there was no difference for the cement factor (p=0.275) nor for the ceramic/cement interaction (p=0.161). The feldspathic ceramic showed the highest values of ΔE 00 . Variations in L*, a*, b*, c* and h* were more significant for feldspathic ceramic. In conclusion, storage alters similarly the optical properties of the resin cements and feldspathic porcelain was more susceptible to cement color change after aging.

“…However, previous studies done on the discoloring effects of a dark abutment have shown that fabricating ceramic restorations with thicknesses of 2.0mm or greater have the best chance at masking the underlying tooth shade. Yet it is often unreasonable or disadvantageous to reduce a tooth to this "ideal" amount since pulpal health or restorability may be compromised in place of esthetics (Niu, Agustin, & Douglas, 2014). Irreversible pulpitis can become a concern when 63-73% of tooth structure is typically removed during traditional crown preparations (Tariq F. Alghazzawi, Lemons, Liu, Essig, & Janowski, 2012).…”

“…Lithium disilicate was originally marketed by the Ivoclar Vivadent company as IPS Empress II and has since gained popularity due to its observed strength, chemical durability, abrasion pattern, and impressive esthetics (Giordano & McLaren, 2010;Niu et al, 2014). Prior to undergoing heat treatment and becoming fully crystalized, it is comprised of two crystal nuclei, namely lithium disilicate and lithium metasilicate (Della Bona, Nogueira, & Pecho, 2014).…”

“…One reasonable method in mitigating a darker abutment shade in the esthetic zone would be to use a ceramic core of medium or high opacity, further layered by veneering ceramic (Chaiyabutr, Kois, Lebeau, & Nunokawa, 2011). applying the cement to the brim of the 0.3mm thick PVS mold (Niu et al, 2014). An LED light (SmartLite, Dentsply, York, PA, USA) was used to cure the resin cement sample for 20 seconds at wavelength of 460nm to ensure adequate polymerization.…”

: In restoration dentistry clinicians need to control the effect of the ceramic thickness and cement shade to achieve successful colorimetric results when allceramic veneers are bonded. The purpose of this study was to evaluate the in vitro effects of cement color and the thickness of the final shade on porcelain discs. The study sample comprised 120 e.max Press HT A-2 ceramic discs of two thicknesses (60 of 1 mm thick and 60 of 0.5 mm thick). Three different lightnesses of Variolink Veneer cement were used (23, 0, and 13) for the cementation process. An Easyshade spectrophotometer was used to measure color coordinates (L*, C*, h, a*, and b*) on the discs both before and after cementation. To a large extent, color changes (DE Ã ab ) after the cementation process were found to depend on cement thickness, ceramic thickness, and cement lightness. This model predicted 52% of the observed variability. The most marked change in color appeared on discs 0.5 mm thick and a cement lightness of 23 (DE Ã ab 5 12.0 units). By contrast, color was more stable (minor changes) on discs with a cement lightness of 13 (DE Ã ab 5 2.3 units). All color coordinates were significantly modified after bonding, both on thin and thick discs and in all three cement color groups (23, 0, and 13). However the difference in color (DE
