Globular Structures Associated with the Completion of the Enamel Matrix in the Rat

¹ Dental School, University of St. Andrews, Dundee, Great Britain

The globules and nodular structures found in the ameloblast layer and stratum intermedium in the enamel organ of the rat at the end of the formation of the enamel matrix were interpreted as arising from cellular degeneration in these layers. It was suggested that the cellular degeneration is part of the profound alteration in the enamel organ associated with the change from the phase of matrix formation to that of maturation.
