“…The thickness of the specimens was kept constant and they were measured over two different backgrounds (white and black), as color perception is dependent on sample thickness [25][26][27], opacity [28] and background [29]. According to Ardu et al [17], white background represents the clinical situation of a class III or class V restorations, where composite overlaps a residual part of natural enamel and, eventually, dentin.…”

The aim of this in vitro study was to determine the influence of the order of composite layers' stratification on resin composites color and appearance when restoring an anterior composite tooth on the 3D color coordinates L*a*b* by use of a spectrophotometer. A total of 192 discs samples made of two different commercial available composite materials (Miris 2 and HRI) of enamel (E) and dentin (D) shade, each with a 1 mm thickness, were divided into 6 configurations. The superposition of 4 samples for a total of 16 specimens per group determined the investigated configurations. All groups showed significant (p \ 0.05) differences between them except groups E1DDE and EDDE1 which represent the same order of stratification, measured from the buccal side and from the palatal side. Perceptible differences were detected between all groups except for E1DDE, EDDE1 and EDDD, independent of the background (white or black). The realization of the palatal layer with dentin composite shade did not change the final outcome within the limit of a total 4 mm thickness in comparison to the palatal layer with enamel composite shade.

“…Composite resin restoration may be employed for anterior teeth esthetic rehabilitation; but, in order to restore translucency, chroma, and value, composite stratification techniques should be used. Unfortunately, layered composite restorations are time consuming and the clinicians, as well as patients, should be aware of the limitations encountering with composite stratification techniques as well as their longevity . Conversely, the costs for direct composite restorations are usually lower than that of indirect restorative procedures and easier to color match.…”

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).

“…Thereby, this kind of product should not be adopted to restore anterior teeth in case of high esthetic requests, in fact, as reported by Friebel et al . [16] the clinical recommendation for front teeth would be to use a dentin composite to mask the dark background of the oral cavity and have a translucent edge of about 1-2 mm at the crown of the tooth, making the reconstruction appear more natural by using the layering technique with translucent enamel shades.…”

Background:The properties of the composite materials and the clinical expertise while layering them carry many esthetic implications in restorative dentistry.Aims:The aim of the present study is to assess the influence of scattering properties of G-aenial A2 shade on color perception when used in esthetic restorations.Materials and Methods:Two composite resins were evaluated in this study: Gradia Direct (shade A3) and G-aenial (shade A2). A colorimetric evaluation according to the CIE L*a*b* system, relative to standard illuminant A against a white background, was performed to assess the referred chameleonic properties of G-aenial when used in simulated clinical situations.Statistical Analysis Used:The differences in color change between the test group G-aenial and the test Group Gradia Direct were considered clinically not perceptible (ΔE* <3.3). Differently, the differences in color change were considered clinically perceptible (ΔE* >3.3) between the control group G-aenial and the control group Gradia Direct and between the test group G-aenial and the control specimens obtained with G-aenial. The CIE Lab parameters which brought to ΔE were investigated using t-test (P < 0.05).Results and Conclusions:Color harmonization in simulated clinical conditions depends on different factors related to dentine and to composite resins. In this study dentine variables were dropped in order to analyze the influence of thickness and of the composition of the composite resin.
