A study was undertaken to evaluate the influence of light intensity on the ability to discriminate color differences within the color range of natural teeth. The results show that shade selection is not significantly affected within the range of 75 to 300 fc. Neither the specialty of the dentist nor the amount of time in practice appeared to be a factor in making color discriminations. However, 7 of the 50 dentists serving as subjects were found to be color defective, and a difference was found between their color discrimination abilities and those of normal persons. This suggests that color-defective dentists should obtain assistance when matching tooth shades.
开展了一项研究，以评估光强度对辨别天然牙齿颜色范围内颜色差异能力的影响。结果表明，在75至300英尺烛光的范围内，比色选择没有受到显著影响。牙医的专业程度和从业时间长短似乎都不是进行颜色辨别的因素。然而，在作为受试者的50名牙医中，有7名被发现存在色觉缺陷，并且发现他们的颜色辨别能力与正常人的存在差异。这表明，色觉有缺陷的牙医在进行牙齿比色时应寻求帮助。
