The enamel organ isolated from the maturation zone was treated with hydrochloric acid to remove such extracellular materials as collagen fibrils and basal lamina covering the papillary layer. Two types of the ridges were classified on the basis of their morphology and distribution: (1) globular and irregularly arranged ridges at the periphery of the early maturation zone, (2) elliptical and parallel ridges in the central part of this zone and over the whole of the late maturation zone. The fine surface structures of the ridges were characterized by numerous interdigitating cell processes.
从成熟区分离出的成釉器用盐酸处理，以去除覆盖乳头层的细胞外物质，如胶原纤维和基底层。根据其形态和分布将两种类型的嵴进行了分类：(1) 早期成熟区周边的球形且排列不规则的嵴；(2) 该区域中部及整个晚期成熟区的椭圆形且平行的嵴。这些嵴的精细表面结构的特征是有许多相互交错的细胞突起。
