Summary
At the submicroscopic level, extracellular globular membrane-delimited structures have been observed in the matrix in early dentin formation in the rat. Within these “dentinal globules”, needle-like crystallites are found before apatite crystals appear in the filamentous-amorphous ground substance. In sections incubated for alkaline phosphatase, reaction products are closely associated with these globules. The possible role of the globules in initial dentin formation is discussed.
