摘要：

背景：关于四环素牙的美学修复大多局限于临床上的观察，而基础的实验研究相对较少。
目的：观察Cerinate瓷贴面修复轻度(黄色)、中度(黑灰色)、重度(黄-灰色)、极重度(灰褐色)4种不同染色程度模拟四环素牙的颜色变化。
方法：将模拟四环素牙试件按轻、中、重、极重度4种不同染色程度分为4组，每组10个试件，用Cerinate瓷贴面进行修复，Panavia F遮色树脂黏结剂黏结，用电子测色仪测定修复体黏结前及黏结后的L*、a*、b*值及变化。
结果与结论：瓷贴面黏结前与黏结后的表面的L*、a*、b*值之间差异有显著性意义(P < 0.05)。轻度四环素牙选用未含有遮色剂的树脂黏结剂黏结会较小，中、重度四环素牙在用含有遮色剂的遮色树脂黏结剂黏结后对修复体的颜色遮色效果较好，而对极重度四环素牙遮色效果不好，最好选用其他修复体修复。

Abstract:

BACKGROUND: Aesthetic repair on tetracycline stained teeth is mostly confined to the clinical observation, while the experimental study is relatively few.
OBJECTIVE: To study the color changes of Cerinate porcelain veneer repaired tetracycline stained teeth: mild (yellow), moderate (dark gray), severe (yellow-gray), very severe (taupe).
METHODS: Simulated tetracycline stained teeth were divided according to staining degree into four groups: mild, moderate, severe, and very severe groups; each group had ten specimens which were repaired with Cerinate porcelain veneer, bonded with Panavia F opaque resin adhesive. The L*, a*, b* values of specimens before and after bonding was measured by electronic color measurement instrument.
RESULTS AND CONCLUSION: Before and after bonding, the values of L*, a*, b* were significantly different (P < 0.05). Mild tetracycline stained teeth bonded using resin adhesive without opaque bonding have a better effect than moderate and severe tetracycline stained teeth bonded with opaque resin adhesive; while, it is best to use other restorations to repair very severe tetracycline stained teeth.
