THE RELATIONSHIP BETWEEN TOOTH COLOR, SKIN AND EYE COLOR
Purpose: Tooth shade is one of the most important factors in dental and facial aesthetics. The purpose of this study was the determination of tooth shades of the upper frontal teeth in subjects and their comparison with different skin and eye color.
Materials and methods: Subjects’ tooth color measurements were determined using an intraoral spectrophotometer Vita Easyshade® (Vita Zahnfabrik. H Rauter GmbH & Co. KG. Bad Sackingen. Germany). The measurements were made in 255 patients in the intercanine sector of maxilla. The color of skin and eyes were 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. The Pearson Chi-square test was used to observe the differences between tooth color, and skin and eye color.
Results: In the central incisors the most frequent shade registered was 2M1 in 62 subjects (8.10%), in lateral incisors 1.5M1.5 in 65 (8.50%), and in canines 2M3 in 142 subjects (18.56%). The Pearson Chi-square test results showed that there was a significant statistical difference in relation of central incisors to skin and eye color (p<0.01; p<0.001); in lateral incisors p<0.001, and in canines p<0.001 (p=0.001). On the other hand, in the relation of lateral incisors and canines to eye color (p>0.05) the significant statistical difference was not observed.
Conclusion: The skin and eye color significantly correlate with the tooth color, except in the relation of lateral incisors and canines to eye color.
