Materials and methods The shades of 40 human incisors were determined using a spectrophotometer, with the teeth divided into four groups of the same shade (n = 10). The following single-shade resin composites were tested: Omnichroma, Charisma Diamond One, Vittra Unique, and Essentia Universal. The specimens were prepared as dual and single. Standardized cavity preparations (diameter, 7 mm; depth, 2 mm) were prepared in human incisor teeth and then restored for dual specimens. Composite duplicates of human incisors were prepared with resin composites for single specimens (n = 10). The color match of these specimens to that of unrestored human incisors was compared, and the color difference (Delta E*) was calculated. Independent observers conducted a visual evaluation of the specimens and scored them. CAP-I and CAP-V values were determined. A one-way analysis of variance test was used for statistical analysis (p < 0.05). Results There was no statistically significant difference between the CAP-V and CAP-I values of the tested single-shade resin composites (p > 0.05). All the materials tested had acceptable color-matching potential. Conclusions In terms of color matching, there were no significant differences between the different tooth shades of all the tested resin composites.en10.1007/s00784-022-04737-xinfo:eu-repo/semantics/closedAccessColor Adjustment PotentialBlendingChameleon EffectSingle ShadeResin CompositeTranslucencyStorageBorderGlossArticle272889896Q2WOS:0008663752000012-s2.0-8513966921136222960Q1
