摘要：

背景：光固化复合树脂在现代牙科美容修复中占重要位置，广泛用于临床牙体缺损的直接修复，可产生与牙体相似的颜色效果。
目的：综述光固化复合树脂乳光、荧光效应的影响因素及研究现状。
方法：由第一作者检索1989-01/2010-11中国期刊全文数据库和PubMed数据库，中文检索词“光固化复合树脂，颜色，乳光，荧光”，英文检索词“resin composite，illumination，filler，scattering，opalescence，fluorescence，color”，初检到129篇文献，依纳入排除标准，保留34篇归纳总结。
结果与结论：光固化复合树脂材料能模拟天然牙的乳光性、荧光性，其中，光固化复合树脂中直径接近蓝光的无机填料对蓝光的散射、感光的有机基质对紫外光的吸收可以模拟天然牙，分别产生材料的乳光或荧光效应；它们受光源条件、材料状态以及临床相关操作等的影响，也可以影响光固化复合树脂的遮色力。

Abstract:

BACKGROUND: In esthetic restorative dentistry, light-cured resin composites are widely applied in direct repairing dental defects due to their excellent color performance. 
OBJECTIVE: To review research status of influencing factors on the opalescence and fluorescence of light-cured resin composites.
METHODS: Databases of CNKI and PubMed were retrieved by the first author to research the papers with the key words of “resin composite, illumination, filler, scattering, opalescence, fluorescence, color”. Papers underlying light mechanism, characteristics, and research status were included. In total 129 documents were initial searched, and 34 ones were included in the final analysis.
RESULTS AND CONCLUSION: The light-cured resin composites, in particular, scattering of inorganic filler with similar diameter to blue light and absorption of photoreceptive organic matrix to ultraviolet light, have similar properties of opalescence and fluorescence as those of natural teeth. Opalescence and fluorescence of light-cured resin composite were affected by illumination, resin composition and relevant clinical performances, which may further influence the masking effect of resin composites.
