Abstract
Influence of Surrounding Conditions on Visual Determination of Tooth Shade
Highlights
In addition to the undeniable need for functional aspects in restorative and reconstructive dentistry, the esthetic appearance of fixed restorations gaining an increasing importance today
All participants were tested with Color Vision Deficiency Test (CVD) using a beamer projection of the Ishihara test charts, before starting the test[26] The Toothguide-Training-Box (TTB, VITA Zahnfabrik, Figure 1) performs color matching under reproducible conditions, designed by Jakstat in 2002 and later improved in 2007[13]
Differences for the cutoff ∆E > 3 in the proportion of ∆E values >3 between the individual colors and the reference color “grey” are significantly recognizable.The ∆E values ∆E >3 are between 42.7 % and 61.1 %.In comparison with reference, the statistical evaluation of the proportion of ∆E >3 is significantly different for yellow background (P =.001), blue and red environment (P
Summary
In addition to the undeniable need for functional aspects in restorative and reconstructive dentistry, the esthetic appearance of fixed restorations gaining an increasing importance today. Three training phases and a final test of the Toothguide-Training Box (Vita Zahnfabrik) used Gulden et al in their research to compared color shade-matching ability of graduate students and dental technician students[9]. Dudea et al performed color matching of 10 color-competent observers under reproducible conditions (optical geometry, viewing distance) under two different illumination (6500K and 5000K) and 5 different colored surroundings (grey, white, and black, red and light blue)[20]. Their results showed that observers with perfect color matching competence achieved better matching results compared to those with the average color discrimination competence.
