Incisors of the rodent family are widely used as a convenient material for the study of odontogenesis, and the rodent otontogenic cells have been electron microscopically and histologically studied in recent years.
With the introduction of a scanning electron microscope, various dental tissues have been investigated by this useful research tool. Even so, the published literature on the odontogenic cells in the light of scanning microscopy is still scanty. BOYDE [1] reported his findings on scanning micrographs of the canine ameloblasts and ISOKAWA et al. [2] on the odontoblasts of man respectively. Since the work of BOYDE was not chiefly directed to the observation of aemloblasts, he did not describe details of the ameloblastic cells themselves.
The present study is concerned with a scanning micrographic inquiry of the ameloblasts of rat incisors together with the enamel rods.
