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.
首先，二次矿化增加从表面向深层出现；然后，三次矿化增加从深层向表面发生；最后，狭窄的表层下矿化严重，达到所有层中最高的矿化程度。
