Abstract：
The study aimed to analyze whether age determines the lightness and darkness of tooth shades. The demand for esthetics has soared to a next level progressively in many developing countries including India; the importance provided to match the tooth shade creates a great difference in the satisfactory outcome of the patient in the field of dentistry. Therefore, this particular study analyzed the differences in tooth shade values based on age factor among the Indian population. 238 individual\'s case sheets with the age between 18 and 65 years. 18-30 years of age were considered as group 1 (young adults), 31-45 years in group 2 (middle age), and above 45 years in group 3 (older age). The clinical intraoral pictures of the patients which were taken prior to the treatment were obtained and the shade of any one of the upper permanent central incisors was assessed using the Vitapan 3D-Master shade guide, especially the middle portion of the facial surface of the incisors. The collected data were imported to Statistical Package for the Social Sciences, version 17 (IBM Corporation). Chi-square test was used to assess the significance. From the data, 17.2% showed A1 shade, 35.2% A2 shade, 7.5% A3 shade, 5% A4 shade, 7.1% B1 shade, 15.9% B2 shade, 7.1% B3 shade, 3.3% B4 shade, and 1.1% C1 shade. The individuals under the category of above 45 years showed darker tooth shade compared to young adults and middle age population (Chi-square test, P < 0.001). Significant association was established with darker tooth shades by increasing age and vice versa. The older age population showed a higher correlation for dark shade between teeth. The aging process significantly affects the teeth color. Hence, as a dentist, it is important to know about the distribution of tooth shade and its association with age to get an outcome with adequate patient satisfaction.
摘要：
该研究旨在分析年龄是否决定牙齿阴影的明暗程度。在包括印度在内的许多发展中国家，对美学的需求已逐步上升到一个新的水平；匹配牙齿阴影的重要性在牙科领域的患者满意的结果中产生了巨大的差异。因此,这项特殊的研究分析了印度人群中基于年龄因素的牙齿阴影值的差异。238张年龄在18至65岁之间的个人案例单。18-30岁被视为第1组（年轻人），第2组（中年）31-45岁，第3组45岁以上（年龄较大）。获得患者在治疗前拍摄的临床口腔内照片，并使用Vitapan3D-Master阴影指南评估任何一个上永久性中央切牙的阴影，尤其是门牙表面的中间部分。收集的数据被导入到社会科学统计软件包中，版本17（IBM公司）。使用卡方检验来评估显著性。从数据来看,17.2%显示A1阴影，35.2%A2灯罩,7.5%A3灯罩,5%A4灯罩,7.1%B1灯罩,15.9%B2阴影，7.1%B3灯罩,3.3%B4灯罩,和1.1%C1阴影。与年轻人和中年人群相比，45岁以上类别的个体显示出较深的牙齿阴影（卡方检验，P<0.001)。随着年龄的增长，与较深的牙齿阴影建立了显着的关联，反之亦然。老年人群对牙齿之间的深色阴影显示出更高的相关性。老化过程显着影响牙齿颜色。因此，作为一名牙医,重要的是要了解牙齿阴影的分布及其与年龄的关系，以获得患者满意的结果。
