Basement membrane reconstitution and cytodifferentiation of odontoblasts in isochronal and heterochronal reassociations of enamel organs and pulps.

The restoration of the basement membrane and the terminal differentiation of odontoblasts were studied in iso- and heterochronal reassociations between dental mesenchyme and enamel organs. It was suggested that the cytodifferentiation of odontoblasts was triggered by the basement membrane secreted by the enamel organ of a specific stage.
