Color difference thresholds for computer ‐simulated human Gingiva

ConclusionsThe difference between the perceptibility and acceptability threshold for gingiva was statistically significant in both CIEDE2000 and CIELAB. The same was true for differences between the corresponding thresholds using two color difference formulas, and between dentists and laypersons. Visual thresholds of human gingiva were not dependent upon lightness of adjacent teeth. Overall, CIEDE2000 color difference formula provided better fit than CIELAB formula in the evaluation of color difference thresholds of human gingiva. Clinical SignificanceThe data on visual thresholds for healthy human gingiva can be used as quality control tool/guide for selection and evaluation of dental materials, interpretation of color‐related findings in clinical dentistry and research, and for standardization in dentistry. It is of particular value that this study was designed based on in‐vivo color evaluation of healthy keratinized gingiva of subjects of different ethnicities, age groups, and gender.
