Replicas of unerupted and erupted human enamel submitted to protein‐disrupting solutions showed: (1) an inequal distribution of porosities in the subsurface; (2) such porosities were restricted gradually in each enamel subunit (enamel segments limited by two perikymata). First the whole surface was covered by a network, reduced at a later stage to half of the surface and ultimately the porosities were present only in the perikymata. This paper confirms the occurrence of a late maturation at stage where cells are no longer active and details the time‐dependent involution of these porosities.
