Abstract
Background: Proper evaluation and analysis of color distribution of shade guides is
important to achieve clinically acceptable color matches in everyday dentistry. Therefore,
the aim of our study was to determinate the color of natural teeth in selected population
group and compare it with the color distribution of three different commercially available
shade guides. Methods and materials: The color of maxillary central incisors (n=235) was
measured us middle third of the labial surface in patients from age range 18-69 years. Color values of
natural teeth and shade tabs from the shade guides Vita Classical, Ivoclar chromascop and
Vita3D Master were recorded according to CIE Lab color space. Descriptive statistic and ttest
were used to determine whether the color differences seen in the samples were
statistically different. Results: The range of values for the parameters of the natural tooth
color were for L*60.04-81.21 for a* 0.88- 8.54, b* 10.37-26.26. All attributes of the maxillary
central incisor displayed a broader range than those from the shade guides. The 1-sample t
test revealed a significant difference (P<.001) between means of color ranges for all values.
and in order to select the best match for a restoration we need to make compromise for
finding the lowest color difference. Beside the subjectivity of the visual methods in color
determination in dentistry mismatches also can originate from the selected shade guide.
