需要新的成像技术来早期检测牙齿之间近端接触部位的龋齿(龋齿)。以往的测量表明，牙釉质在1300 nm的近红外波段是高度透明的。在这项研究中，工作在1300 nm的近红外成像系统被用来通过不同厚度和整个牙齿的牙齿切片获取图像，以展示近红外牙齿透照系统在早期龋齿(龋齿)成像中的应用。模拟天然龋齿的光散射的病变被放置在平行牙釉质切片上。通过对采集的投影图像进行分析，计算模拟病变与周围声学牙釉质的对比度。结果显示病变和牙釉质之间有明显的对比(>；0.35)，在厚度为6.75 mm的样本中，空间线轮廓清楚地显示了病变。这项研究清楚地表明，近红外透照系统在早期龋齿成像方面具有相当大的潜力。(C)2003年美国光学学会。
New imaging technologies are needed for the early detection of dental caries ( decay) in the interproximal contact sites between teeth. Previous measurements have demonstrated that dental enamel is highly transparent in the near-IR at 1300-nm. In this study, a near-IR imaging system operating at 1300-nm was used to acquire images through tooth sections of varying thickness and whole teeth in order to demonstrate the utility of a near-IR dental transillumination system for the imaging of early dental caries ( decay). Simulated lesions, which model the optical scattering of natural dental caries, were placed in plano-parallel dental enamel sections. The contrast ratio between the simulated lesions and surrounding sound enamel was calculated from analysis of acquired projection images. The results show significant contrast between the lesion and the enamel (> 0.35) and a spatial line profile that clearly resolves the lesion in samples as thick as 6.75-mm. This study clearly demonstrates that a near-IR transillumination system has considerable potential for the imaging of early dental decay. (C) 2003 Optical Society of America.
