Enamel is the outer-most layer of mammalian teeth and serves as a multi-functional coating that provides protection to the vital underlying tissues. In the permanent dentition of humans, tooth enamel must resist fatigue and wear over a lifetime, which extends over tens of millions of cycles. The damage tolerance of enamel is unparalleled by any other naturally occurring mineralized tissue. Previous studies have attributed this behavior to composition gradients, mineralogical variations, and microstructure across the enamel thickness. More recently, however, a distinct aspect of the meso-scale structure regarded as decussation has been credited for its resilience. Decussation refers to a complex weaving pattern of the enamel rods that is exhibited by the inner enamel. Details of this pattern have been elusive. This study aimed to develop a more comprehensive view of decussation in human enamel and presents a preliminary “unit-cell” concept for 3D printing materials with enamel-like microstructure.
