A replica of natural gingival color can be fabricated in a prosthesis. A precise record of gingival color helps to follow-up oral and systemic diseases. A healthy gingival color according to the "Periodontal Workshop Committee I" is 'pink' but no indication is given for color variations by age or position. For more precise definition, therefore, gingival color was examined in the maxillary and mandibular anterior regions by visual color matching using standard color chips after Munsell's system. Gingival color was measured in 60 subjects, in 18 locations around the anterior teeth. 1. The gingival color varies in Hue from 10 RP to 2.5 YR, being mainly between 2.5 R and 5 R; in Value from 4 to 8, maximum between 6 and 7.5; and in Chroma from 1.5 to 7, mainly from 4 to 5. 2. No difference in gingival color is recognized between the male and female, or between left and right sides of the jaw. 3. Gingival color varies with the position of papillary, marginal, and attached gingivae, and the parts corresponding to different teeth have different colors. 4. The gingival color of young persons, differs markedly from that of older people. In all the parts, red Hue is more tinged with purple in the old than in the young; Value is higher in the young; and Chroma is higher in the old.
可以在修复体中制作出与天然牙龈颜色相似的复制品。精确记录牙龈颜色有助于对口腔和全身疾病进行随访。根据“牙周研讨会委员会I”的标准，健康牙龈的颜色为“粉红色”，但未提及年龄或位置导致的颜色变化。因此，为了更精确地定义牙龈颜色，我们使用孟塞尔系统的标准色卡，通过视觉颜色匹配的方法，对上颌和下颌前部区域的牙龈颜色进行了检查。我们对60名受试者前牙周围18个位置的牙龈颜色进行了测量。1. 牙龈颜色的色调从10 RP到2.5 YR不等，主要在2.5 R和5 R之间；明度从4到8，最大值在6到7.5之间；彩度从1.5到7，主要在4到5之间。2. 男性和女性之间，以及颌骨左右两侧之间的牙龈颜色没有差异。3. 牙龈颜色随乳头龈、边缘龈和附着龈的位置而变化，与不同牙齿相对应的部位颜色不同。4. 年轻人的牙龈颜色与老年人的明显不同。在所有部位，老年人的红色调比年轻人更偏紫；年轻人的明度更高；老年人的彩度更高。
