Abstract
Purpose
To
evaluate the shade matching capabilities in natural dentitions using
Vita Toothguide 3D-Master and an intraoral digital spectrophotometer
(Vita Easyshade Advance 4.0) in various light sources.
Materials and Methods
Participants
between 20 and 40 years old with natural, unrestored right maxillary
central incisors, no history of bleaching, orthodontic treatment, or
malocclusion and no rotations were included. According to their shades,
subjects were randomly selected and grouped into A1, A2, and A3. A total
of 100 participants (50 male and 50 female) in each group were chosen
for this study. Shade selection was made between 10 am and 2 pm for all
light sources. The same examiner selected the shade of natural teeth
with Vita Toothguide 3D-Master under natural light within 2 minutes.
Once the Vita Toothguide 3D-Masterwas matched with the maxillary right
central incisor, the L*, a*, and b* values, chroma, and hue were
recorded with Vita Easyshade Advance 4.0 by placing it on the shade tab
under the same light source. The values were statistically analyzed
using one-way ANOVA and Tukey's HSD post hoc test with SPSS v22.0
software.
Results
The mean ∆E*ab values for shades A1, A2, and A3 for groups 1, 2, and 3 were statistically significantly different from each other (p < 0.001).
Conclusion
The
intraoral digital spectrophotometer showed statistically significant
differences in shade matching compared to Vita Toothguide 3D-Master.
Incandescent light showed more accurate shade matching than the filtered
LED, LED, and daylight.
