早期蛀牙可以再矿化，而不需要“钻补”治疗，这种治疗更具侵入性，也不那么持久。然而，早期的龋齿病变通常表现为白色背景上的白斑，导致许多病变只有在它们发展到再矿化程度之后才被识别为蛀牙。我们提出了一种空间频域成像技术来表征牙组织的光学特性。该技术使不同的牙组织类型（健康的牙釉质，健康的牙本质和受损或脱矿的牙釉质）能够很容易地相互区分，并允许量化牙组织的减少散射系数。使用850 nm的近红外光可以深度穿透组织并抑制吸收效应，确保只观察到牙釉质脱矿直接导致的散射系数降低的变化，并简化了分析方法。这项技术提供了一种工具，既可以指导牙医关注感兴趣的区域和潜在的脱矿，也可以提供纵向量化评估，以监测龋病的长期行为。
Early stage dental caries can be remineralized without the need for “drill-and-fill” treatments that are more invasive and less permanent. However, early stage caries lesions typically present as a white spot on a white background, resulting in many lesions only being identified after they have developed beyond the point of remineralization as cavities. We present a spatial frequency domain imaging technique to characterize the optical properties of dental tissue. This technique enables different dental tissue types (healthy enamel, healthy dentin and damaged or demineralized enamel) to be easily distinguished from one another and allows quantification of the reduced scattering coefficients of dental tissue. The use of near-infrared light at 850 nm allows high depth penetration into the tissue and suppression of absorption effects, ensuring only changes in the reduced scattering coefficient that result directly from demineralization of enamel are observed and simplifying the analysis method. This technique provides a tool to both guide the attention of dentists to areas of interest and potential demineralization, and to provide longitudinal quantified assessments to monitor caries lesion behaviour over time.
