Abstract：
BACKGROUND: Gingival shade matching, often overlooked, plays an integral role in designing prostheses for patients with high smile lines, gingival defects, and cases where the acrylic flange of removable dentures extends into the aesthetic zone. The purpose of this study was to find the most prevalent gingival shade in a sample of the South Indian population.
METHODS: A total of 110 participants were included in the study based on the inclusion and exclusion criteria. The standard daylight method of shade matching was used for this study. The participants were seated in a dental chair in the vertical position with their heads supported, their mouths open, and cheek retractors in place. The study area, gingiva, and vestibular region in relation to maxillary and mandibular right central incisors were dried with a three-way syringe, 15cm away, for 3 seconds before shade matching for 5 seconds at each reference point with an Ivoclar Vivadent IPS Dsign shade guide.
CONCLUSIONS: The most prevalent shade in the marginal and vestibular regions of the gingiva of the South Indian population was found to be GM2 shade, while the most prevalent shade of the attached gingiva was found to be G2 shade. A good percentage of the attached gingival shade was not matched with the tabs available in this shade guide.

摘要：
背景：牙龈阴影匹配，经常被忽视,在为微笑线条高的患者设计假体中起着不可或缺的作用，牙龈缺损，以及可移动假牙的丙烯酸法兰延伸到美学区域的情况。这项研究的目的是在南印度人口样本中找到最普遍的牙龈阴影。
方法：根据纳入和排除标准，共有110名参与者被纳入研究。本研究采用标准日光匹配法。参与者坐在垂直位置的牙科椅上，头部支撑着，他们的嘴巴张开，和脸颊牵开器就位。研究区域,牙龈,与上颌和下颌右中切牙相关的前庭区域用三通注射器干燥，15厘米远，持续3秒，然后在每个参考点与IvoclarVivadentIPSDsign遮阳指南匹配5秒。
结论：发现南印度人群牙龈边缘和前庭区域最普遍的阴影是GM2阴影，而发现附着的牙龈最普遍的阴影是G2阴影。附着的牙龈阴影的很大比例与此阴影指南中可用的标签不匹配。
