“…Worldwide, VITA classic (VITA Zahnfabrik, Bad Säckingen, Germany) is the most widely used shade guide in dental practice and the laboratory 1,2) . The organization of the different colored tabs was empirically based while the evidence-based VITA 3D-Master shade guides, Bleachguide, and Linearguide, all manufactured by VITA, cover the color range of human teeth more adequately and thus enhance the likelihood of successful shade matching [2][3][4][5][6] . The lack of standardization in production leads to equivocal findings on color consistency among shade guides even by the same manufacturer 7) .…”

The aim of this study was to compare the agreement rate (%) and color difference (ΔE*ab) of three dental color-measuring devices, with the visual shade identification. The tooth color were determined by two operators, which were advised to select a VITA classic shade tab in each other's agreement. The Shadepilot (SP), CrystalEye (CE) and ShadeVision (SV) were used to measure tooth color. Statistically analyses include agreement rate (%), color difference (ΔE*ab), McNemar test (p=0.05), Student's t-test (p=0.05) and Bland Altman scatterplots. The SP had an agreement of 56.3% with the visual shade determination, the CE 49.0% and SV 51.3%. ΔE*ab of the visually and instrumentally selected shade tabs and natural teeth were frequently above the threshold for acceptability. Comparing both methods, for SP ΔE*ab values differ in a range of clinical acceptability.

“…(6)(7)(8)(9) There have also been reported discrepancies related within similar shade tab from the same manufacturer, and also between different shade guide systems. (10)(11) Therefore, absolute care must be followed in performing shade matching including handling and sterilization of the shade guide itself. Manufacturer's recommendation for sterilization of conventional shade guide includes chemical disinfectants with solutions that doesn't include component of phenol or methyl ethyl ketone.…”

Abstract:Objective: To evaluate the effect of long term utilization of chemical disinfectants on the color of porcelain shade guides.Methodology: three chemical disinfectants were used in this study: Minuten spray, Lysol ICQuaternary Disinfectant Cleaner (QDC), and Lysol IC Ready to Use Disinfectant Cleaner (RDC). Simulation of disinfecting cycles for one year, two years, and three years were done on Vita 3D master shade guide. Color differences were determined by visual inspection and analyzing ΔE.Results: ΔE values were significantly below the perceptible (ΔE=1) and the clinically acceptable (ΔE=3.7) thresholds. Conclusions:Simulated utilization of Minuten Spray, Lysol IC (QDC), and Lysol (RDC) disinfectants for up to three years didn't cause a clinically significant difference in the color of VITA Toothguide 3D-Master Shade Guide.
