目的：??探讨光学相干断层成像技术（OCT）对釉质早期龋的成像和量化评估效能，为其在早期龋临床诊断中的应用提供实验依据。方法??采用OCT扫描牛牙光滑面早期人工龋模型和脱矿模型，获取釉质图像和光学信息，并与偏振光显微镜图像和原子吸收光谱测得的矿质损失量进行对比，采用SPSS软件包配对t检验和Pearson相关性分析进行数据分析。结果??早期龋及脱矿釉质OCT图像与偏光显微镜图像基本相符；OCT测得的早期龋组釉质的总反射率改变量低于脱矿组（P<0.05），脱矿深度在两组间无统计学差异（P>0.05）。釉质总反射率改变量与矿质损失量呈正相关（P<0.05）。结论??OCT能够无创地、较准确地显示釉质早期龋的矿质改变，量化其病变范围和程度，在早期龋的临床诊断方面具有广阔的应用前景。
