Figure 7
3D renderings of five samples (on the left), showing longitudinally sliced volumes portraying tooth and restoration materials virtually cropped (grey), on which the interfacial gaps between dentin and adhesive layer are depicted in 3D (red). Thickness maps (middle) of the interfacial gaps show a spatially varying distribution around the imaged region. The calibration bar represents the thickness of the gaps. Quantitative evaluation of the percentage of gaps measured in 18 segments around the axis of the post reveals strong orientation variation with certain regions of debonding exceeding 80% of the surface area.
