Value, chroma, and hue of gingiva of 100 black and 100 white patients were measured clinically with Munsell color tabs under fluorescent light and under simulated daylight. The color of uniformly pigmented attached gingiva of both blacks and whites was described most often by a value between 5/ and 7/, a chroma of /4, and a range of hues from 2.5R to 7.5R when determined under fluorescent light. The color of gingiva pigmented by melanin in 61 black patients was lower in value (3/ to 4/) and chroma (/1 to /2) but had a similar range of hues compared with uniformly pigmented gingiva. The use of a simulated daylight source instead of a fluorescent light present in the clinic resulted in a modest change in color described by an I of no more than 3.6.
在荧光灯下和模拟日光下,使用孟塞尔色卡对100名黑人患者和100名白人患者的牙龈颜色、色度和色调进行了临床测量。在荧光灯下测定时,黑人和白人均匀色素沉着的附着龈颜色最常描述为明度在5/至7/之间、色度为/4、色调范围为2.5R至7.5R。61名黑人患者中由黑色素沉着的牙龈颜色,其明度(3/至4/)和色度(/1至/2)较低,但与均匀色素沉着的牙龈相比,色调范围相似。使用模拟日光光源而非诊所中现有的荧光灯,导致所描述颜色的变化不大,明度变化不超过3.6。
