“…In addition, 44% of studies used more than one methodology to evaluate the masking ability 7,10,12–14,26,33,35,38,40,46,47,49,54–56 . From the studies that used ΔE, 95% used the CIELAB color difference equation (ΔE* ab ) 3,4–14,26,30–54,56–62 and 14% used the CIEDE2000 color difference equation (ΔE 00 ) 11,26,50,54,56,59 . When the masking ability was evaluated using the translucency parameter (TP), 95% of the studies used conventional TP 7,8,11,12,14,26,33,35,38,40,46,47,49,56,62 and 11% used the translucency parameter based on the CIEDE2000 color difference equation (TP 00 ) 56–58 …”

“…11,31,32,41,43,47,48,56,58 However, most of the studies evaluated the masking ability of zirconia-based ceramics (3Y-TZP), either as monolithic restorations 4,47,51,52,53,55,56,63 or as infrastructures. 47,52,55,56 The influence of the cement system on the masking ability of darkened substrates has been evaluated by several studies, 6,26,35,36,38,39,42,44,45,49 showing that the type of cement used with indirect restorations influences on the final color of these restorations. Cement systems with opaque characteristics showed higher masking ability for darkened substrates.…”

“…[56][57][58] It is a clinical challenge to select esthetic restorative materials and structures capable of masking an undesirable color substrate. Thus, several clinical and laboratory studies were performed simulating darkened dental substrates using metallic structures, [4][5][6]31,47,51,52,57,61,62 tetracycline stained dentin, 3 acrylic resins, 14,34,51 resin-based composites, 4,6,9,11,35,36,45,47,[50][51][52][53][54][55][56]58,60 and ceramics. 7,30,40,41,43,56,58 The thickness of the evaluated structures is a critical parameter for the analysis of the color and optical properties of materials.…”

“…38 Considering different ceramic systems to mask darkened substrates, the feldspathic porcelains and lithium disilicate glass-ceramics were effective to improve the esthetics of ceramic restorations. 11,31,32,41,43,47,48,56,58 However, most of the studies evaluated the masking ability of zirconia-based ceramics (3Y-TZP), either as monolithic restorations 4,47,51,52,53,55,56,63 or as infrastructures. 47,52,55,56 The influence of the cement system on the masking ability of darkened substrates has been evaluated by several studies, 6,26,35,36,38,39,42,44,45,49 showing that the type of cement used with indirect restorations influences on the final color of these restorations.…”

Objective: To conduct a systematic review on the masking ability of discolored substrates, analyzing the capacity and quality of the response produced by the different methodologies and techniques applied to overcome this clinical challenge. Materials and methods:The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The electronic search was conducted in MEDLINE/PubMed, Scopus and Web of Science databases, without date restriction. In vitro studies, written in English, applying different methodologies to evaluate masking ability were included. The variables of interest were: type, color and thickness of the restorative and/or cement material; use of pigments in the restorative material and/or cement; color of the substrate; and background color used for the evaluations.Results: Database search retrieved 307 eligible papers with a final inclusion of 47 published papers. Approximately 98% of the studies used ΔE, 36% used TP, and only 6% used CR to evaluate the masking ability of restorative materials. Conclusions:The most appropriate methodology to evaluate the masking ability is using color difference equations (ΔE) associated with the perceptibility and acceptability thresholds.Clinical significance: As different methodologies have been used to evaluate the masking ability of esthetic restorative materials on colored substrates, there is an urgent need to reach a consensus and propose a method, which is suggested by the present systematic review.

Polyetheretherketone (PEEK) is a promising implant material because of its excellent mechanical characteristics. Although this polymer is a standard material in spinal applications, PEEK is not in use in the manufacturing of dental implants, where titanium is still the most‐used material. This may be caused by its relative bio‐inertness. By the use of various surface modification techniques, efforts have been made to enhance its osseointegrative characteristics to enable the polymer to be used in dentistry. In this feature paper, the state‐of‐the‐art for dental implants is given and different surface modification techniques of PEEK are discussed. The focus will lie on a covalently attached surface layer mimicking natural bone. The usage of such covalently anchored biomimetic composite materials combines many advantageous properties: A biocompatible organic matrix and a mineral component provide the cells with a surrounding close to natural bone. Bone‐related cells may not recognize the implant as a foreign body and therefore, may heal and integrate faster and more firmly. Because neither metal‐based nor ceramics are ideal material candidates for a dental implant, the combination of PEEK and a covalently anchored mineralized biopolymer layer may be the start of the desired evolution in dental surgery.

Front Cover: The figure schematically depicts a bioinspired composite coating on a Polyether ether ketone (PEEK) dental screw, which consists of a covalently linked modified polysaccharide that was mineralized with Calcium phosphate. The background shows a fluorescence image of a coated PEEK‐screw after an in vivo study, highlighting a successful ingrowth of the implant into the surrounding bone. This is reported by Jennifer Knaus, Dietmar Schaffarczyk, and Helmut Cölfen in article 1900239.
