Tooth color and shade can have an important influence on a person's appearance. Brown and white enamel dysmineralization defects, white hypocalcification lesions, and natural variations in tooth shading can detract from an otherwise attractive smile. Bonded facial composite resins, porcelain veneers, or full-coverage restorations can be used for color correction. A more conservative and less expensive approach is to eliminate or reduce the discoloration. In select cases this can be done without removing significant tooth structure and without placing restorative material to mask the tooth. This article describes a combination of "microreduction," microabrasion, and dental bleaching for tooth color correction that has worked well for certain patients. The method is easily performed, conservative, inexpensive, and requires minimal subsequent maintenance.
牙齿的颜色和色度会对人的外貌产生重要影响。棕色和白色的牙釉质脱矿缺陷、白色的钙化不全病变以及牙齿色度的自然差异，都会有损原本迷人的笑容。粘结式面部复合树脂、烤瓷贴面或全冠修复体可用于牙齿颜色矫正。一种更为保守且成本较低的方法是消除或减少牙齿变色。在某些情况下，无需去除大量牙体组织且无需放置修复材料来遮盖牙齿即可做到这一点。本文介绍了一种“微磨除”、微酸蚀和牙齿漂白相结合的牙齿颜色矫正方法，该方法对某些患者效果良好。该方法操作简便、保守、成本低且后续维护需求极少。
