The most frequently seen intra-oral soft tissue is the gingiva. Most often, it is seen as coral-pink tissue that surrounds the neck of the teeth. Gingiva that encircles the tooth necks and covers the alveolar processes of the jaws is an intra-oral tissue that exhibits biomimetic features. The wide range of colors of the gingiva depends on the configuration of gingival vascularity, the degree of epithelial cornification, level of melanogenesis, and the depth of epithelialization. However, the color of the gingiva varies depending on the degree of melanin pigmentation. The current study aimed to identify the different distribution patterns of gingival color and determine the correlation between skin color, gender, and geographical area of origin.
A total of 839 subjects were involved in the study where the gingival color and skin tone were measured using the Dummett-Gupta Oral pigmentation Index (DOPI) combined with VITA VMK MASTER and skin shade method developed by Revlon (USA) and L'Oreal (France) for makeup foundation shades. One investigator was calibrated for the examination of the colors after being tested for normal color vision and color aptitude using the line test.
A significant association was found between skin color and gingival pigmentation (χ2 value (6) = 114.48; P = 0.001). It was also found that females (67.1%) significantly had darker gingiva than males (58.3%). The study statistics display that location of the individual was also statistically associated with melanin pigmentation of the gingiva (χ2 value (57) = 559.33; P = 0.001).
The study concluded that gender, skin color, and individual location are significantly associated with gingival melanin pigmentation.
最常见的口腔软组织是牙龈。它通常呈现珊瑚粉色，环绕着牙齿颈部。围绕牙颈部并覆盖颌骨牙槽突的牙龈是一种具有仿生特征的口腔组织。牙龈的广泛颜色取决于牙龈血管的形态、上皮角化程度、黑色素生成程度和上皮化深度。然而，牙龈的颜色因黑色素色素沉着程度而异。本研究旨在确定不同的牙龈颜色分布模式，并确定肤色、性别和原籍地理区域之间的相关性。
共有 839 名受试者参与了这项研究，使用 Dummett-Gupta 口腔色素指数（DOPI）结合 VITA VMK MASTER 和 Revlon（美国）和 L'Oreal（法国）开发的用于化妆粉底色调的皮肤色调方法测量牙龈颜色和肤色。一位调查员在接受线测试正常色觉和色觉能力测试后，经过校准，用于检查颜色。
发现肤色与牙龈色素沉着之间存在显著相关性（χ2 值（6）= 114.48；P = 0.001）。还发现女性（67.1%）的牙龈明显比男性（58.3%）更暗。研究统计数据显示，个体的位置也与牙龈黑色素沉着的统计学相关（χ2 值（57）= 559.33；P = 0.001）。
该研究得出结论，性别、肤色和个体位置与牙龈黑色素沉着显著相关。
