<p>(A)MicroCT image of a 109, longitudinal section. Depending on the tooth height up to nine equal spaced (10 mm) horizontal sections presenting a complete layer of peripheral enamel were selected for measurements. Additionally the most occlusal section (mo) of the crown showing a complete layer of peripheral enamel was selected. (B,D) MicroCT cross section showing the typical arrangement of the dental substances of an upper (B) and lower (D) cheek tooth. (C,E) MicroCt cross section as in B,D with selected enamel (yellow), dentine (light red) and cementum (blue) to define areas for measurement.</p
