摘　　要：目的：从色度学定量分析角度探讨３种进口光敏树脂与中国人天然牙冠色范围之吻合情况。方法：选取３种临床上常用之进口光敏树脂为实验材料，在标准背景下以分光光度计测定其色度值后，与天然牙冠色度范围进行比较，分析其色度分布差异。结果：３种中任何一种进口光敏树脂之色度分布范围均小于但位于天然牙冠色范围之中，即不能达到与天然牙色度范围的完全重合，并且在分布上各有特点。结论：进口树脂的色度学指标稍异于中国人天然牙冠色度学指标范围。bjective: To compare the color of 3 kinds of imported composite resin with tooth crown of Chinese. Methods: The color of 3 kinds of imported composite resin and that of Chinese tooth crown of normal individuals was measured based on standard background with spectrum colorimeter.Results: The color distribution space of the 3 kinds of resin were smaller than that of Chinese tooth crown, but the centers were almost same. There were significant color distribution difference between imported resins and Chinese tooth crown.Conclusion: The color distribution spaces of imported composite resins were different from that of Chinese tooth crown, and any one kind of composite resin can not meet the color demand from dental clinic.
