“…The appearance of a full‐ceramic restoration is influenced by the color of the underlying tooth structures, the color, and thickness of the luting cement, the color and optical properties of the restorative material, surface texture, and glaze . The thickness of the restorative material is also contributing to the outcome of the restoration and there are studies demonstrating the close relationship between the masking effect and thickness . However, there are certain situations in practice, particularly in the case of discolored teeth, when a large amount of tooth structure cannot be removed without jeopardizing the vitality of teeth.…”

“…The final color of all-ceramic restorations depends on three main factors and their interaction: color of the tooth/substructure; thickness of ceramic and resin cement, and ceramic system and resin cement type (11,12). Resin cements may mask the underlying color and modify the final color of the restoration; therefore, controlling and balancing its opacity and color parameters is key to achieve good final aesthetic outcomes (13).…”

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.

“…Milled ceramic restorations may also be translucent depending on the composition, thickness, and inherent translucency of the CAD blocks . An increase in lithium disilicate glass‐ceramic thickness may minimize the influence of background color due to an increase in opacity of the restoration . However, any increase in restoration thickness would require more aggressive tooth preparation.…”

The suggested decision-making aims to facilitate clinicians' selection of the most appropriate restorative technique for reproducing color and appearance of anterior teeth after ultra-conservative preparation and according to different clinical scenarios CLINICAL SIGNIFICANCE: The selection of the appropriate ceramic material for each case is of major importance, since the entire treatment plan will be determined based on the type of ceramic material that will be used for the final restoration. Each restorative material has a specific tooth preparation requirement, indications, and limitations that shall be respected for maximum esthetical outcomes. (J Esthet Restor Dent 28:267-276, 2016).
