“…The data processing method is very important for the final outcome of research on visual thresholds. As for the fitting procedure used, it was reported that TSK fuzzy approximation provided more robust results than S‐shaped curves in 50:50% threshold estimation . It presents a more flexible and adaptable behavior to approximate the data.…”

“…Color is one of the most important esthetic parameters in dentistry, and visual judgment is the most frequently used method of evaluating color in dentistry. There are two major thresholds for assessing color differences: perceptibility threshold (PT) and acceptability threshold (AT) . These thresholds can serve as a quality control tool to guide the selection of dental materials, evaluate their clinical performance, and interpret visual and instrumental findings in clinical dentistry, dental research, and subsequent standardization.…”

Visual color difference thresholds can serve as a quality control tool to guide the selection of esthetic dental materials, evaluate clinical performance, and interpret visual and instrumental findings in clinical dentistry, dental research, and subsequent standardization. The importance of quality control in dentistry is reinforced by increased esthetic demands of patients and dental professionals.

“…The values obtained in this study for the CIEDE2000 acceptability/perceptibility thresholds corresponded approximately to 70% of the values obtained using the CIELAB formula. In 2011, an additional study suggested the acceptability thresholds for lightness, chroma and hue differences for dental ceramics . The authors found acceptability values of 2.92 ΔL′, 2,52ΔC′ and 1.90ΔH′.…”

“…Color measurements performed with accurate color measuring systems can overcome the shortcomings of inconsistent visual methods in shade-matching, bleaching, and quality control [2,5]. To provide an objective standard for instrumental assessments of color stability of acrylic denture base resins, color difference indicators, including perceptibility and acceptability thresholds, have been exhaustively studied in dental materials that mimic tooth or skin colors [5][6][7][8][9][10][11][12][13] and have been recommended by ISO technical report 28642 [14], need to be investigated.…”

Abstract. This study aimed to set evaluation indicators, i.e., perceptibility and acceptability color difference thresholds, of color stability for acrylic denture base resins for a spectrophotometric assessing method, which offered an alternative to the visual method described in ISO 20795-1:2013. A total of 291 disk specimens 50±1 mm in diameter and 0.5±0.1 mm thick were prepared (ISO 20795-1:2013) and processed through radiation tests in an accelerated aging chamber (ISO 7491:2000) for increasing times of 0 to 42 hours. Color alterations were measured with a spectrophotometer and evaluated using the CIE L*a*b* colorimetric system. Color differences were calculated through the CIEDE2000 color difference formula. Thirty-two dental professionals without color vision deficiencies completed perceptibility and acceptability assessments under controlled conditions in vitro. An S-curve fitting procedure was used to analyze the 50:50% perceptibility and acceptability thresholds. Furthermore, perceptibility and acceptability against the differences of the three color attributes, lightness, chroma, and hue, were also investigated. According to the S-curve fitting procedure, the 50:50% SHUFHSWLELOLW\ WKUHVKROG ZDV ¨(00 (r 2 =0.88) and the 50:50% DFFHSWDELOLW\ WKUHVKROG ZDV ¨(00 (r 2 =0.89). Within the limitations of this study, 1.71/4.00 ¨E00 could be used as perceptibility/acceptability thresholds for acrylic denture base resins.
