Abstract

Optical coherence tomography (OCT) is a non-invasive, radiation-free optical technique for caries diagnosis. The presented study dealt with the correlation of conventional caries detection methods and using polarisation-sensitive OCT (PS-OCT). Human extracted carious teeth were assessed by dentists with visual and radiographic examination and PS-OCT images were gained. Proximal lesions could be detected early in the intensity-based OCT cross-sectional images. The degree of polarization can clearly delineate proximal caries from surrounding healthy tooth structure. The obtained results pave the way to reduce invasive filling therapy through early possibilities of intervention.
