Progressive mineralization pattern of developing enamel during the maturation stage.
The maturation stage of developing enamel may be divided into three substages: First, a secondary mineralization increase appears from the surface toward the deeper layer; then, a tertiary mineralization increase takes place from the deeper layer toward the surface; and finally, the narrow subsurface layer mineralizes heavily and attains the highest degree of mineralization of all layers.
