Figure 4

Two cross-sectional slices of Tooth 2 (marked as S3a and S3b in Figure 3) are presented. The presence of an accessory canal (yellow arrows) is observed in the slice S3a within the SWIFT image and non-decalcified histology section, but not observed in the CBCT section. In slice S3b, the extent of the composite resin restorations are identifiable within the SWIFT section as well as in the CBCT and histological sections. The slice thickness is equal to 156 μm for SWIFT and 200 μm for CBCT images.
