摘要：

背景：平滑面早期牙釉质龋虽然已发生脱矿改变但无肉眼可见的龋洞形成，目前临床采用的常规检测方法难以对其准确诊断。
目的：应用光学相干断层成像技术对平滑面早期牙釉质龋的量化研究进展进行综述。
方法：由第一作者检索CNKI和EBSCO HOST数据库中1979/2011发表的关于光学相干断层成像技术定量研究平滑面早期龋的相关文献，以“光学相干断层成像，早期龋，平滑面，量化评估”和“optical coherence tomography, early caries, smooth surface，quantitative assessment”为检索词进行检索。纳入31篇进行综述。
结果与结论：新兴的光学相干断层成像技术能够检测龋变牙釉质的背向散射信号使脱矿牙釉质成像，并应用深度、反射率、衰减系数等定量指标对平滑面早期牙釉质龋进行量化评估，为牙釉质早期龋的诊断提供了新的方法。

Abstract:

BACKGROUND: Early enamel caries on the smooth surface is the subsurface demineralization limited in the enamel with an intact surface. It is difficult for routine clinical methods to make a definite diagnosis of early caries.
OBJECTIVE: To summarize the histological characteristics and detecting methods of early enamel caries on the smooth surface, and the progress of quantitative assessment by optical coherence tomography.
METHODS: Literatures about quantitative assessment of early caries on the smooth surface based on optical coherence tomography from CNKI and EBSCO HOST databases published from 1979 to 2011 were searched by the first author. The key words were “optical coherence tomography, early caries, smooth surface, quantitative assessment” both in English and Chinese. Papers published recently or in authoritative journals were selected. Totally 78 documents were initially searched and 31 included in this review.
RESULTS AND CONCLUSION: The new technology, optical coherence tomography, which can image the demineralized enamel through detecting the back scatter signals and quantify early enamel caries with the parameters such as depth, reflectivity and attenuation coefficient, provides a new evidence to the diagnosis of early enamel caries.
