Odontogenesis of the Rat Molar

Abstract
The embryology of the rat molar was studied in a 24 hr. age series. By means of a modification of the Long and Evans method, embryos of relatively known age were secured. Heads of 156 embryo were sectioned and stained with hematoxylin and eosin (Wilder, Masson and Mallory). The daily development, from 13 days in utero to birth, was descr. in detail. The dynamics of odontogenesis as well as the cytomorphosis of each element and its function were descr. and discussed.
