Enamel forms the outer surface of teeth, which are of complex shape and are loaded in a multitude of ways during function. Enamel has previously been assumed to be formed from discrete rods and to be markedly aniostropic, but marked anisotropy might be expected to lead to frequent fracture. Since frequent fracture is not observed, we measured enamel organization using histology, imaging, and fracture mechanics modalities, and compared enamel with crystalline hydroxyapatite (Hap), its major… 
Influence of structural hierarchy on the fracture behaviour of tooth enamel

TLDR
This review critically evaluates the role of hierarchy on the development of the R-curve and the stress–strain behaviour and attempts to identify and quantify the multiple mechanisms responsible for this behaviour as well as their impact on damage tolerance.
Discrete element models of tooth enamel, a complex three-dimensional biological composite.
Structural Integrity of Enamel: Experimental and Modeling
TLDR
It is reported that enamel can absorb indentation energy through shear deformation within its protein layers between apatite crystallites, which will help guide the design of the nanostructural architecture of dental restorative materials.
Compositional Determinants of Mechanical Properties of Enamel
TLDR
Analysis of the data showed that the structural organization of enamel affects its micromechanical properties, which will help guide the development of bio-inspired nanostructured materials for mineralized tissue repair and regeneration.
The hidden structure of human enamel
TLDR
It is shown that the crystalline c-axes are homogenously oriented in interrod crystals across most of the enamel layer thickness, and molecular dynamics simulations demonstrate that the observed mis-orientations of adjacent crystals induce crack deflection.

Enamelin Directs Crystallite Organization at the Enamel-Dentine Junction
TLDR
The aim of this study was to characterize the structure of ENAM-mutated enamel to develop a deeper understanding of the role of enamelin protein during formation with regard to crystal organization and to aid better clinical diagnosis and tailor-made treatment.
Repair of tooth enamel by a biomimetic mineralization frontier ensuring epitaxial growth
TLDR
It is revealed that a rationally designed material composed of calcium phosphate ion clusters can be used to produce a precursor layer to induce the epitaxial crystal growth of enamel apatite, which mimics the biomineralization crystalline-amorphous frontier of hard tissue development in nature.
Biomineralization of a Self-assembled, Soft-Matrix Precursor: Enamel
TLDR
This approach led to an assessment of amelogenin protein self-assembly that, when altered, disrupts fabrication of the soft enamel protein matrix and results in loss of cell-to-matrix contacts essential to fabrication and mineralization.

TLDR
Failure patterns of enamel in normal and abnormal use can be explained by their varicosities, which reflect daily variations in the rate of production; their cross-sectional shape; the non-parallelism of adjacent groups; and the support of any one microscopic tissue element by other tissue, including dentine, placed to resist an applied load.
The Effects of Enamel Anisotropy on the Distribution of Stress in a Tooth
TLDR
If enamel is indeed anisotropic, its function differs greatly from that suggested in previous hypotheses, as it would provide a hard-wearing protective surface-coating while simultaneously diverting the load away from this brittle, low-tensile-strength phase, thus reducing the potential for tooth fracture.
Growth tracks in dental enamel.

TLDR
The geometry of the enamel growth tracks and their chronological significance are valuable tools in chronological mapping of dental development and for understanding temporal and spatial patterns in tooth morphogenesis, and the taxonomic significance of prism packing patterns, prism decussation and enamel thickness should be clarified through further systematic descriptive research.
Indentation Damage and Mechanical Properties of Human Enamel and Dentin
TLDR
In indentation studies to understand the microfracture and deformation and the microcrackmicrostructure interactions of teeth, it is concluded that the cracks strongly interact with the DEJ and the enamel rods, and that the mechanical properties of teeth are functions of microstructural orientations.

  • A. Boyde

  • 1979
TLDR
It is proposed that each enamel crystallite has a carbonate-rich center, and the correlation between the loss of carbonate (and magnesium) and the losses of the crystal centers is pointed to.
Evidence for amelogenin "nanospheres" as functional components of secretory-stage enamel matrix.
TLDR
It is postulated that the amelogenin monomers self-assemble to form nanospheres which function to space the initial crystallites, control crystal habit, inhibit intercrystalline fusions, and, through the apposition of their surfaces, create anionic channels which facilitate ion transport within the mineralizing matrix.
