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.
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.
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.
Skin and eye color significantly correlate with tooth color; however, the color of lateral incisors and canines does not correlate significantly with eye color.
牙齿颜色是口腔和面部美学中最重要的因素之一。本研究的目的是确定受试者上颌前牙的牙齿颜色，并与不同的肤色和眼睛颜色进行比较。
使用口腔分光光度计Vita Easyshade（德国巴德萨克根的维他齿科工厂，H Rauter GmbH & Co. KG）对255名患者上颌尖牙间区域的牙齿颜色进行测定。通过视觉感知确定肤色和眼睛颜色。分光光度计记录了Vita牙齿比色板3D Master（德国巴德萨克根的维他齿科工厂，H Rauter GmbH & Co, KG）的色阶。采用Pearson卡方检验来检验牙齿颜色与肤色和眼睛颜色之间的差异。
中切牙记录到的最常见色阶是2M1（62名受试者，8.10%）；侧切牙是1.5M1.5（65名受试者，8.50%）；尖牙是2M3（142名受试者，18.56%）。Pearson卡方检验结果显示，肤色和眼睛颜色与中切牙颜色（p<0.01；p<0.001）、侧切牙颜色（p<0.001）和尖牙颜色（p<0.001；p=0.001）之间的关系存在统计学显著差异。另一方面，侧切牙和尖牙与眼睛颜色的关系未观察到显著差异。
肤色和眼睛颜色与牙齿颜色显著相关；然而，侧切牙和尖牙的颜色与眼睛颜色没有显著相关性。
