    Demineralization Affects Refractive Indices of Human Enamel and Dentin

    Objectives: Dental hard tissues and biomaterials can be non-destructively assessed using optical coherence tomography (OCT), an emerging diagnostic tool. Swept Source (SS)-OCT has an improved imaging resolution and speed. Depth resolved data obtained in B-scans can be used to assess the quality and depth-resolved information on the tissues. The measurements are affected by the optical properties of the tissue, such as refractive index (RI). The aim of this study was to examine the effects of demineralization on the refractive index of enamel and dentin using SS-OCT. Methods: In the first experiment, slices cut from human sound molars approximately 300 ...
