Achieving similar features to those on natural teeth is a common problem with esthetic restorations. Color matching is a fundamental procedure required to perform a predictable composite resin restoration. It is no longer enough to measure these criteria with conventional shade guides, which provide the hue and chroma, but do not take into account other dimensions of the tooth such as value, intensives, opalescence and characterizations. The present article presents a simple and effective technique for color selection using a digital photograph of the tooth and an image-editing program such as Adobe Photoshop or Picture Project. The digital editing of the photograph with two simple steps described in this paper reveals the internal structures of the tooth easily. The modified photographs highlight the opalescence, white spots, shape of the internal mammelons and other features that are not visible at first glance. This procedure provides an accurate color chart with which the clinician can begin an esthetic restoration process.
实现与天然牙齿相似的特征是美学修复中常见的问题。颜色匹配是进行可预测的复合树脂修复所需的基本步骤。仅用传统的比色板来衡量这些标准已不再足够，传统比色板能提供色调和彩度，但没有考虑牙齿的其他维度，如明度、饱和度、乳光和特征。本文介绍了一种简单有效的颜色选择技术，使用牙齿的数码照片和图像编辑程序，如Adobe Photoshop或Picture Project。通过本文所述的两个简单步骤对照片进行数字编辑，可以轻松揭示牙齿的内部结构。修改后的照片突出了乳光、白斑、内部隆突的形状和其他乍一看不明显的特征。这一过程提供了一个准确的色卡，临床医生可以据此开始美学修复过程。
