Mandibular first molar with occlusal pain. a Buccal view. Full coverage metal crown complicated the visual inspection and clinical diagnosis. SS-OCT observation was performed along the red line in order to image the cross-sectional view of cervical zone horizontally. b SS-OCT image at red line in (a). A strong reflection penetrating into dentin indicates presence of vertical crack in root dentin (red arrow)

Mentions: Strong reflection from the material surfaces appears to be effective in conventional OCT setups for detecting the reflective signal from the fault, e.g., the border of cavitated caries, tooth fractures, and interfacial gaps of tooth restorations [13••, 17••, 18–20, Figs. 1, 2, and 3]. In addition, several lines of evidence report that the reflectivity of smooth surface caries lesions can be distinguished against sound enamel with OCT without polarization sensitivity, and the lesion contrast can be evaluated by post acquisition image processing [22, 29, 30, 32, 33•, 51–54].Fig. 1
