SS-OCT images of dentin caries at approximal surface obtained noninvasively (A1, B1) and corresponding histological view after cross-sectioning (A2, B2).
In SS-OCT, dentin caries is imaged as a bright zone. Lesion expanding along the DEJ is imaged as distinct bright line (arrow 1). A strong reflection penetrating into the structure indicates the lesion is “cavitated” (arrow 2).
A1, A2: Superficial dentin caries
B1, B2: Deep dentin caries
