Research Abstract

Swept-source optical coherence tomography (SS-OCT) can construct cross-sectional images of biological structures. The purpose of this study was to evaluate the possibility to introduce SS-OCT in restorative dentistry.In operative dentistry, SS-OCT was examined to evaluate the diagnostic accuracy for the detection of caries and tooth crack. Refractive indices of enamel and dentin and attenuation coefficient were measured using SS-OCT. We also establish a method for non-destructive detection of gap and secondary caries beneath composite restorations. In endodontics, SS-OCT was used for the detection of root fracture, imaging the pulp chamber, and detection of second mesiobuccal canal of maxillary molars. In the field of fixed prosthodontics, influence of dentin alteration due to aging on OCT imaging was evaluated. In composite restorations, wear is one critical problem in clinic. Subsurface cracks underneath wear traces were observed.
