Abstract

Objectives

The reproducibility of electronic color-measuring devices used in dentistry refers to the consistency of measurements of a single device and also that between identical devices. This in vitro study evaluated the short-term interdevice agreement of eight equivalent dental measurement devices.

Methods

The short-term repeatability of eight identical VITA Easyshade Advance color measurement devices was evaluated. Each device was used to quantify the Commission Internationale de l’Eclairage (CIE) L*a*b* color coordinates of ceramic disks, designed in accordance with guidelines set by the VITA Toothguide 3D-Master shade tab organization. Statistical analysis involved calculating the intraclass correlation coefficients (ICCs) and color differences (ΔE*) for corresponding measurements taken by the devices. In addition, the mean color difference from the mean (MCDM) was calculated for each color.

Results

All devices showed high ICCs for the color coordinates (L = 0.996, a = 0.993, b = 0.999). The ΔE* by shade ranged from 0.62 to 1.67. The MCDM by color-measuring device ranged from 0.11 to 0.23.

Conclusion

This in vitro study showed that the color-measuring devices used were suitable for determining shade with high repeatability.

Clinical relevance

The high interdevice agreement of the VITA Easyshade Advance means that dental professionals can use this device independently, without compromising the consistency and quality of color measurements.
