Comparison of the GAR IVE LRM1 (a) with three modern human teeth affected by different forms of amelogenesis imperfecta (b–d; see Supplementary Text S4for details). Photographs (top), 3D enamel thickness maps (middle) and 2D virtual sections (bottom) show that despite the loss of contrast, GAR IVE has a normal enamel thickness and morphology. Anatomical orientation is shows using ‘M’ for mesial, ‘D’ for distal, ‘B’ for buccal, ‘L’ for lingual and ‘O’ for occlusal. The side of the tooth in front view is circled.
