Physical properties of representative hard tissues [142, 143]

	Crystallographic
	Lattice parameters (Å)		Crystallite size (nm, avg.)	Crystallinity index, b	Ignition products (800 ºC)
	a-axis	c-axis
Bone	9.418	6.884	2.5 × 0.3	33 − 37	HAp
Dentin	9.419	6.880	2 × 0.4	33 − 37	HAp + β-TCMP
Enamel	9.441	6.880	33 × 3	33 − 37	HAp + β-TCMP

Lattice parameters (± 0.003 Å); in substance, the values vary with age

HAp: a-axis = 9.422 Å, c-axis = 6.882 Å, crystallinity index = 100
