Abstract
Near infrared imaging methods, including optical coherence tomography (OCT), have shown promise in assessing activity of enamel caries lesions. We present initial results in ex-vivo dental samples with a polarization diversity-detection OCT system complete with an integrated dental handpiece. Built around an Axsun Technologies swept source engine, images B-scans 12(x) by 7(z) mm at over 100 fps with 66um transverse and 7um depth resolution. Internal normal dental structure and lesions were imaged and compared with micro-CT. We demonstrate that the Axsun OCT prototype can detect the penetration of occlusal lesions to dentin and measure the penetration of approximal lesions when imaging from the occlusal surface.
