[65] The structure of enamel is also composite in nature between the interrod and rods which also leads to anisotropy. [65] The rod and interrod structure causes anisotropy in enamel as both components have different mechanical properties. Some researchers hypothesize that the lines are a result of the diurnal (circadian), or 24-hour, metabolic rhythm of the ameloblasts producing the enamel matrix, which consists of an active secretory work period followed by an inactive rest period during tooth development. [10] As in all human processes, the creation of enamel is complex, but can generally be divided into two stages. Microabrasion techniques employ both methods.

Enamel is built from closely packed and long, ribbonlike carbonatoapatite crystals (Figure 7-3; see also Figure 7-2) measuring 60 to 70 nm in width and 25 to 30 nm in thickness.The crystals are extremely long; some investigators believe that the length of the crystals actually span s the entire thickness of the enamel layer.

Things in your environment (friction, wear and tear, stress, and corrosion). Enamel is the hardest material in the body and is one of the most durable load-bearing biological materials. [66] The hardness and stiffness parallel to the rod axis results in high hardness and modulus, shown to have modulus values of 85-90 GPa and hardness values of 3.4-3.9 GPa. If you're in need of a paint that forms a hard shell and provides reliable protection, enamel paint just might be the finish that you need.
