Abstract
In this study, an ultrahigh resolution OCT(UHR-OCT) system is constructed, with 1.5 um axial resolution and 1.9 um lateral resolution in enamel. Despite the inverse relationship of clinical process, early-stage dental caries and calculus are both imaged as bright zones on the top of enamel yet cannot be distinguished in conventional OCT. The results indicate that early-stage caries and calculus can be detected and distinguished clearly in our developed UHR-OCT. We also compared the UHR-OCT images with the results obtained from commercial OCT to clarify the system performance. This work shows the potential for using UHR-OCT in early-stage dental detection.
