与可见光检查和数字X射线摄影相比，使用近红外光对牙齿进行口内成像可提高龋齿和修复材料的对比度。本研究的目的是调查近红外光学性质的牙髓室的地板，墙壁和根管口。我们成像在1300-nm和1500-1700-nm的反射和透射，并比较了组织的性质与可见光图像和定量光荧光离体提取的人后牙。后牙在1300 nm和1500-1700 nm的透照产生显着更高的对比度之间的髓室底和壁比所有其他方法。
Intraoral imaging of teeth with near-IR light provides increased contrast of dental caries and restorative materials compared to visible inspection and digital radiography. The objective of this study was to investigate the near-IR optical properties of the dental pulp-chamber floor, walls and canal orifices. We imaged in vitro extracted human posterior teeth at 1300-nm and 1500-1700-nm in reflectance and transillumination and compared the tissues properties with visible light images and quantitative light fluorescence. Transillumination of posterior teeth at both 1300-nm and 1500-1700-nm yielded significantly higher contrast between the pulp-chamber floor and walls than all other methods.
