Figure 1(left): Fracture of glass 'dome' structure simulating failure of dental crown under simulated occlusal load; Figure 2(center): Fracture of extracted human molar tooth under analogous loading conditions; Figure 3(right): Transverse section of human tooth, showing internal closed cracks ('tufts') in enamel; the tufts are sources of weakness, but the complex microstructure constrains crack growth
