Purpose

Tooth color is one of the most important
factors in dental and facial esthetics. The aim of this study was to determine
the tooth color of the upper frontal teeth in subjects and to provide
comparisons with different skin and eye colors.

Material and methods

Tooth color was determined in 255 patients
in the intercanine sector of the maxilla using an intraoral spectrophotometer
Vita Easyshade® (Vita Zahnfabrik. H Rauter GmbH & Co. KG. Bad Sackingen.
Germany). Skin and eye color was determined by visual perception. The shades of
the Vita Tooth Guide 3D Master (Vita Zahnfabrik, H Rauter GmbH & Co, KG,
Bad Sackingen, Germany) were registered by the spectrophotometer. Pearson’s
chi-squared test was used to examine the differences between tooth color and
skin and eye color.

Results

The most frequent shade registered in the
central incisors was 2M1 (62 subjects, 8.10%); in the lateral incisors, 1.5M1.5
(65 subjects, 8.50%); and in the canines, 2M3 (142 subjects, 18.56%). Pearson’s
chi-squared test results showed a statistically significant difference in the
relations between skin and eye color and central incisor color (p<0.01;
p<0.001), lateral incisor color (p<0.001), and canine color (p<0.001;
p=0.001). On the other hand, no significant difference was observed in the
relation of the lateral incisors and canines with eye color.

Conclusion

Skin and eye color significantly correlate
with tooth color; however, the color of lateral incisors and canines does not
correlate significantly with eye color.

Keywords
