Abstract

The structure of dental enamel integrates different levels of functional units, displaying complexity. Rods, synonymous of prisms, and interred, synonymous of interprismatic substance, are the constituting elements of the assembly of calcium/phosphate monocristals elements in dental needle-like HAP [(Ca₁₀(Po₄)₆(OH)₂]. Dental enamel has an internal void volume of 0.2-5%.
